Ah, a new year. Hopefully, 2023 will see you all happy, healthy, and safely on the roads. On my side, we got a new episode of the podcast up, focusing on the numbering on state highways — both the signed numbers and post miles. It’s a really interesting episode. We’re working on the next one — on the history of US highways and their numbering — right now.
As always, I’m looking for interviews:
- For 1.08: We return to the US highway system, so I’m looking for someone from AASHTO on the process for getting highway numbers approved. I’ve got a lead on this…
- For 1.09: We return to the Interstates. We’ll be talking to Andy Field, who did some of the first Interstate highway pages for California and is one of the “A”s behind AARoads.
- For 1.10: We’re looking at the county sign routes. I’m working with the Caltrans Local Assistance Programs office, as well as the LA Department of Public Works.
- For 1.11: I’d like an Assemblycritter to talk about naming resolutions. I’ve sent out a few queries, but no bites as of yet.
If you or someone you know would be interested in helping this project, please contact me.
The headlines for January were lighter. Work slows down in the winter, plus we had all the rains. I’ll note that work for the next round of highway page updates will commence once these headlines are posted. I know I’ve got the January CTC meeting, plus Joel Windmiller has been sending me loads of newspaper articles to go through. I figure I’ll be doing a bunch of work over President’s Day weekend.
Enough of this shameless self-promotion. Here are the headlines that I found about California’s highways for January:

California Highways: Route by Route Podcast
- CARxR 1.07: Highway Numbering: State Highways and Post Miles.In this episode, we explore numbering systems in state highways. It is the start of a four part miniseries on highway numbers in California. Specifically, this episode explores the rhymes and reason for the assigning of signed route numbers to highways with the state shield. This includes looking at the patterns in those numbers, and how the numbering system stands today after the Great Nenumbering. The subsequent episodes in the miniseries will explore the numbering system of US Highways, the numbering of and the history of California’s Interstates, and the signed county route system.The episode also explores another numbering system on state highways: Post Miles. As opposed to sequential mileage numbers as is found in other states, California uses a system called post miles that identifies points along a highway using a combination of a county and a mile point from the southern/western county line, possibly with clarifying prefixes or suffixes. We discuss this system is good detail.Our interview is with Andy Richardson, who retired from Caltrans as a Subject Matter Expert in Geographical Information Systems, Linear Referencing Systems, and Postmiles. Andy worked as a GIS specialist for the State of California since 1988, including Caltrans between 2001 and his retirement in 2021. In his last years at Caltrans, he implemented the Department’s current Linear Referencing System.

- ＄Band of bighorn sheep could stop Caltrans from reopening part of Highway 39 (San Gabriel Valley Tribune). What would prevent Caltrans’ from pursuing its latest attempt to rebuild part of State Route 39 high up in the San Gabriel Mountains, washed away by Mother Nature 44 years ago? The list of possibilities includes more rock slides, giant falling boulders, snowy weather and the cost, which could climb to $57 million or more. But the biggest obstacle standing in the way of Caltrans’ project to repair an official state highway built in 1957 by order of President Dwight D. Eisenhower is a skittish population of protected sheep known for their crowns of curled horns.
- AGC: Billion-Dollar Funds Will Fix Golden State Spans (Construction Eqpt. Guide). As part of the Federal Bipartisan Infrastructure Law, California is receiving approximately $4.2 billion over five years to address the repair and replacement of highway bridges. This translates into $849.4 million in initial funding for the five-year bridge repair program. The bridge formula program represents the largest federal investment ever made to repair and upgrade bridges — dedicating $26.5 billion to states, the District of Columbia and Puerto Rico and $825 million for Tribal transportation facilities. The $849.4 million that California is receiving represents more than double the amount of any other state. The California Department of Transportation (Caltrans) and local transportation agencies in the state will target the funds to improve the nearly 1,500 bridges rated to be in “poor” condition in the state.
- ＄How Disney’s Sierra Nevada ski resort changed environmentalism forever (Los Angeles Times). Let’s start 2023 by looking six decades into the past. That’s how long it’s been since Walt Disney proposed building a massive ski resort at Mineral King, a gorgeous mountain valley in California’s Sierra Nevada bordered on three sides by Sequoia National Park. The ensuing controversy — and Sierra Club lawsuit against the U.S. Forest Service — played a significant role in shaping the modern environmental movement. It’s a story that Daniel Selmi, an emeritus law professor at Loyola Law School in Los Angeles, deftly brings to life in a book released last year, “Dawn at Mineral King Valley: The Sierra Club, the Disney Company, and the Rise of Environmental Law.”
- ＄Widening Highways Doesn’t Fix Traffic. So Why Do We Keep Doing It? (The New York Times). Interstate 710 in Los Angeles is, like the city itself, famous for its traffic. Freight trucks traveling between the city and the port of Long Beach, along with commuters, clog the highway. The trucks idle in the congestion, contributing to poor air quality in surrounding neighborhoods that are home to over one million people. The proposed solution was the same one transportation officials across the country have used since the 1960s: Widen the highway. But while adding lanes can ease congestion initially, it can also encourage people to drive more. A few years after a highway is widened, research shows, traffic — and the greenhouse gas emissions that come along with it — often returns.
- More than $405 million in transit related projects included in FY23 congressionally directed spending (Mass Transit). President Joe Biden signed the Consolidated Appropriations Act, 2023, into law on Dec. 29, 2022, to fund government activities through Fiscal Year (FY) 2023. The act includes $21.2 billion for public transit and $16.6 billion for passenger and freight rail. The bill also includes specific funding for projects designated as “community project funding/congressionally directed spending,” a designation that returned under the FY22 appropriations process. The omnibus package included more than $406 million for more than 140 transit, passenger rail, transit access and transit-oriented development projects. The three accounts under the U.S. Department of Transportation (USDOT) projects received designated funding includes Highway Infrastructure Programs, which included transit access projects, Consolidated Rail Infrastructure and Safety Improvements (CRISI) and Transit Infrastructure Grants, which accounts for $360.5 million of the total transit related project spending. More than $13 million in funding for projects related to transit was included in the designations under the U.S. Department of Housing and Urban Development’s Community Development Fund.
- Biden administration allots $400M for Golden Gate Bridge earthquake upgrades (Marin I-J). A decades-old project to fortify the Golden Gate Bridge to withstand major earthquakes is closer to the finish line after receiving $400 million from the Biden administration. The Federal Highway Administration announced at the end of December that it was allocating $400 million of the $1 trillion federal infrastructure package approved in 2021 to complete the third and final phase of the seismic upgrades on the bridge. Launched in the late 1990s, the project aims to allow the 2-mile span to withstand a magnitude 8.3 earthquake, an event comparable to the destructive 1906 San Francisco earthquake. “This project is as important as any transportation infrastructure project you can find in America,” said Rep. Jared Huffman of San Rafael, who was among a delegation of Bay Area Democrats who wrote to the Biden administration in support of the funds.
- Golden Gate structural project among 1st to get federal Large Bridge grant (Solano Daily Republic). One of the first Large Bridge grants from the federal infrastructure package is a $400 million award to “replace, retrofit and install critical structural elements on the Golden Gate Bridge.” The White House, through the U.S. Department of Transportation’s Federal Highway Administration, announced the grant on Wednesday. Three other grants were awarded: $1.385 billion to rehabilitate and reconfigure the Brent Spence Bridge in Kentucky; $158 million to rehabilitate the northbound structure of the Gold Star Memorial Bridge in Connecticut; and $144 million to rehabilitate four bridges over the Calumet River on the southside of Chicago.
- Solano’s county roads among best in Bay Area; Vallejo among worst (Solano Daily Republic). Solano County’s unincorporated roads rated as “very good” in the Pavement Condition Index for Bay Area Jurisdictions in 2021. It was the third year in a row for the distinction as being among the best roads in the Bay Area, scoring an 80 in 2021, an 80 in 2020 and an 81 in 2019, the report states. There were only six jurisdictions with a “very good” score between 80 and 89 in 2021, and Solano was the lone county. The best ranking, with a score of 84, was Cupertino.
- Where do Sacramento’s main highways take you? (KXTL FOX 40). The Highways and freeways that converge in the Sacramento Metropolitan area can take travelers to different states and even the farthest parts of the contiguous United States. According to the California Highway Patrol Valley Division Office, Sacramento has four major highways including Interstate 5, I-80, U.S. Highway 50, and State Route 99. For your next road trip, here is where Sacramento’s main highways and freeways take you.
- Six Reasons the Metro Board Should Not Approve 57/60 Freeway Widening (Streetsblog Los Angeles). The Metro board has a big decision this month: will they accelerate construction of the agency’s SR-57/SR-60 Interchange Improvements Project? Specifically, the Metro board faces a vote on approving the 57/60 Life of Project budget (LOP) which would mean greenlighting the main phase of project construction. The $400+million 57/60 expansion project is located in the eastern San Gabriel Valley city of Diamond Bar. For about two miles, the 57 and 60 Freeways converge resulting in a congested trunk stretch. Caltrans, Metro, and many elected officials have pushed freeway expansion there as a fix for the traffic congestion. Voters approved $205 million in Metro Measure M sales tax funds scheduled for a 2025 57/60 widening groundbreaking.
- ＄Without 10 deep pockets, Bay Bridge lights will flicker out, nonprofit says (Los Angeles Times). For nearly 10 years, the cascade of lights along the Bay Bridge has illuminated the San Francisco Bay. The public art installation, expected to be removed after just a few years, has become a fixture. Now the bridge may go dark for good. That is, unless Ben Davis can persuade enough millionaires to donate $10 million to keep, expand and upgrade the display. “We have to try,” said Davis, founder of Illuminate. “It’s important to the city, and it’s beautiful.”
- A High Plains Traveler Highway History Essay: The Changing West End of U.S. 70 (highplainstraveler). U.S. 70 is a “x0 route”, one of the original 1926 routes ending in 0, numbers that were generally reserved for routes that crossed most if not all of the country and served major population centers. The west end of U.S. 70 was originally located at Holbrook, in northeastern Arizona. Under the original 1926 plan, that terminus would have been at U.S. 60, but before the routes were marked, original 60 became 66. During the early 1930s, there were several significant revisions to the western terminus of U.S. 70. Ultimately, the route made it all the way to downtown Los Angeles, and filled that cross-country role for around 30 years. With the development of the Interstate system, there was no need for this designation on top of a major cross-country Interstate highway, and the western terminus of the route was moved east to Globe, Arizona. This essay will summarize the shifting west end of this route, the reasons for moving this point, and some of the conflicting issues that made maintenance of the U.S. 70 designation in the far west questionable.
- The speed limit is America’s most broken law. Why can’t we fix it? (Slate, 🎩 Tip: C Patrick Zilliacus). One Tuesday morning this fall, I strapped on a Kevlar vest and slid into the passenger seat of a gray Ford Interceptor sedan, the souped-up Taurus that replaced the Crown Vic as America’s default police car a decade ago.* (And has since been replaced itself: Ford no longer produces police cars, only SUVs and pickups.) This model has several features that are not available for civilian use, including a siren on the roof and a V6 Mustang engine under the hood. That came in handy when Kevin Roberts, a talkative, thoughtful third-year cop, steered us onto Connecticut’s Interstate 84 for the day shift. We were heading toward Waterbury, whose interlocking expressways are his to patrol. Roberts was in the left lane going 80, and I had the uncanny experience of surveying the highway from his point of view. How many times have I been on the other side—overtaking some slowpoke, 12 over the limit, only to see a rack of siren lights in the rearview mirror and ask myself: How slowly can I complete this pass?
- Slip sliding away: The name of the game on scenic Highway 1 (SiliconValley.com). The engineers and laborers who constructed California State Route 1 from Carmel to San Luis Obispo County beginning in the 1920s knew the road was fraught with peril. But they did it anyway. Coastal communities in the area needed better access to health care and other resources. Engineers and prisoners alike risked life and limb as they built the two-lane highway into the majestic coastal cliffs of the Santa Lucia mountains. The 18-year project eventually connected San Luis Obispo to Carmel via the seaside, where the geology makes the road inherently susceptible to landslides. The 1937 grand opening even included a symbolic blasting of a boulder, which the governor cleared from the road with a bulldozer. It was the first of many to come. Now, incessant storms are causing landslide trouble on Highway 1. Again.
- Highway 92 Closed in San Mateo County (NBC Bay Area). Highway 92 in San Mateo County continues to be shut down in both directions and authorities early Friday had no estimated time lanes would reopen. The county sent an alert at about 3:30 a.m. Thursday indicating the closure from upper Skyline Boulevard to Pilarcitos Creek Road. It did not initially specify a reason for the complete closure but later said the hazard was classified as a sinkhole. Motorists were urged to take alternate routes. Caltrans recommended drivers take Highway 1 via Pacifica to get to and from Half Moon Bay. There is another sinkhole on Highway 1 at Pescadero that has traffic down to one lane in that area.
- Caltrans moving toward action on Highway 58 truck-climbing lanes (Tehachapi News). Motorists frustrated by extended delays on Highway 202 between Tehachapi and Cummings Valley have some good news — Caltrans expects paving to begin soon. But there’s even better news from the transportation agency about long-planned truck-climbing lanes on the eastbound side Highway 58 west of Tehachapi. On Jan. 13, Caltrans spokesperson Christopher Andriessen said the District 9 environmental team is nearing completion of the draft environmental document for the State Route 58 Truck Climbing Lane Project.
- Santa Barbara County Begins Long Recovery from Impacts of Recent Storms (Noozhawk). While the rain appears to have moved out Santa Barbara County, with little chance of expected through at least the next week, damages and impacts throughout the South Coast and the rest of the county have been left in the wake of the back-to-back storms. With road closures due to damaged roads, filled debris basins, damage to homes, and more, recovery from the severe storms will likely take some time.
- DOT provides $29.4M to repair California roads damaged by floods (Transport Dive). The Federal Highway Administration is providing $29.4 million in emergency funding to repair California highways, roads, bridges and other infrastructure damaged in flooding in December and January, the agency announced Tuesday. The money is immediately available for use by the California Department of Transportation and four federal land management agencies following severe storm damage that affected as many as 40 of the state’s 58 counties. At least 22 people died as a result of the storms, The Los Angeles Times reported.
- Caltrans will move forward with $165 million Keene Pavement Project (Bakersfield.Com). Caltrans is moving forward on a $165 million project that will remove four curves, replace disintegrating pavement and make other improvements on a 10- to 12-mile stretch of Highway 58 just west of Tehachapi. That section of the highway has been the scene of numerous accidents in recent years, including big rig crashes that resulted in closures lasting many hours. The initial study for what is called the Keene Pavement Project was released last March and the transportation agency accepted public comments through the end of April. Options for the project, the document noted, was that Caltrans could give environmental approval to the proposed project, do additional environmental studies or abandon the project.
- Hwy 70 through Feather River Canyon remains closed indefinitely; new slides occurring (Plumas News). Caltrans District 2 released the latest information on Highway 70 through the Feather River Canyon, this morning, Jan. 26. There continues to be new slide activity, including an event that came down on equipment operating in the area. Luckily, the operator was not injured in the incident. Following is the update: Highway 70 remains closed to through traffic between Jarbo Gap (west of Pulga) and the Greenville Wye (junction with State Route 89) due to continuing slide activity.
- ＄Caltrans discusses South Avenue roundabout (Red Bluff Daily News). Caltrans came to the Tehama County Board of Supervisors Tuesday to talk about the roundabout on South Avenue and State Route 99, or as they are calling it, the South Avenue safety project. Caltrans anticipates starting hard construction activities in the spring of 2024. Project Manager Phil Baker said Caltrans could start some construction activity towards the latter part of the 2023 construction season. Still, it is more likely once a contractor is on board, all the paperwork is complete and all the approval is given, it will be near the end of the construction season. As weather allows, Baker expects to see a project of this nature during the 2024 construction season and completed by the end of 2024.
- History of Route 57 (FB/Edward Weiss). Here you can see the original proposal for the 57 was to end it at its conjunction with the 60.I believe it was in 1967 that the design was amended for the 57 to continue to the 10.Designers just added a extra 3 lanes from 4 to 7 to deal with the added traffic flow
- Federal appropriations bill earmarks $1M for highway project in Salinas Valley (King City Rustler). Transportation Agency for Monterey County (TAMC) announced that the Federal Highway Administration has earmarked $1 million for the “US 101 Auxiliary Lane – South of Salinas” project. The earmark, sponsored by Congressman Jimmy Panetta and Sen. Alex Padilla, is included in the Consolidated Appropriations Act for Fiscal Year 2023, which President Biden signed last week. “We are grateful to Congressman Panetta and Sen. Padilla for their support to secure this funding to extend the US 101 northbound acceleration lane at Spence Road,” said Todd Muck, executive director of TAMC. “… We now have the full funding needed to start construction in 2023. The project is expected to be completed in 2024 and will improve safety along one of the primary routes that connects Northern and Southern California.”
- Bicyclists Weigh in on Highway 39 Reopening in San Gabriel Mountains (Streetsblog Los Angeles). Public comment will close soon for the reopening plans for the northmost tip of Highway 39 in the San Gabriel Mountains, at its junction with Angeles Crest Highway 2. Until Monday January 16, the public can try to influence which of six options Caltrans will move forward with. These include: no build, emergency vehicles only, active transportation use, full reopening, building a separate viaduct, and a single travel lane. SBLA spoke to several bike club members about their hopes for it (as well as a Caltrans representative and the Mayor of Azusa). They gave a variety of takes.
- 71/91 Interchange Project (Riverside County Transportation Commission). The Riverside County Transportation Commission, in partnership with Caltrans, is reconstructing the 71/91 Interchange Project in Corona. Construction will take place from early 2023 to 2025. The 71/91 Interchange serves as a gateway between Riverside, Orange and San Bernardino Counties and is a vital link for commuters and freight vehicles that travel along the 91 and the 71. The new non-tolled interchange is designed to improve safety, expand access to other modes of travel, reduce greenhouse gas emissions, and enhance traffic flow. The project will support continued movement through this area by native wildlife such as mountain lions, bobcats, and coyotes.
- Caltrans looking to elevate Highway 37 between Vallejo and Marin County (Vallejo Sun). The California Department of Transportation is seeking to elevate state Highway 37 between Vallejo and Marin County to protect the flood-prone highway from sea level rise from climate change. Caltrans conducted a study of options starting in the fall of 2020 as the agency predicted worsening flooding over the coming decades, with the entire corridor between Novato and Vallejo expected to be permanently submerged by 2100.
- Erosion appears to be worsening on PCH (Malibu Times). A series of storms battering California appears to be worsening erosion on a vulnerable Malibu beach. Yellow caution tape extends along a 50-yard stretch of embankment on Pacific Coast Highway just north of Coastline Drive. This precarious ridge of sand abutting Malibu’s thoroughfare into Santa Monica and Los Angeles looks dangerously close to crumbling into the Pacific below. An LA County Beaches and Harbors crew placed the caution tape to keep beachgoers off the unstable shoulder “in the interest of public safety,” according to its spokesperson. But the agency also claims “protecting the highway itself is Caltrans’ responsibility.”
- PART 1: Beyond the 710 – It Was Bleak (ColoradoBoulevard.net). In 2014, I was Mayor of South Pasadena, a city known for a long-standing 710 Freeway fight which began in 1947. The support for the Tunnel’s approval was gaining momentum, and on its way through the Metro administered Environmental Impact Report (EIR) process as the locally preferred alternative. After a long, meandering legal path through several route variations, the SR-710 freeway was still on the State’s Highway Code and on the Southern California Association of Governments (SCAG) Regional Transportation Plan’s project list with $780 million in available Measure R funds being leveraged for additional private investor funds. Legal battles waged on with the City of Alhambra and Caltrans to complete the planned freeway intended to continue northward of Valley Boulevard to Pasadena. The City of South Pasadena was politically isolated and the sole vote opposing the Tunnel (out of 35) at the San Gabriel Valley Council of Governments (SGVCOG). The prevailing sentiment on the South Pasadena City Council was that the City of South Pasadena was going to have to rely on activists’ protest tactics and lawsuits to fight the freeway yet again, after decades of costly litigation and political isolation.
- SF’s Central Freeway, Embarcadero eyed for changes (Bay Area Reporter). Voters’ decisions last November to ratify two closures of major San Francisco thoroughfares to cars may prefigure further, more substantial changes to where drivers can rev their engines. Gay state Senator Scott Wiener (D-San Francisco) made the dramatic announcement late last year via Twitter that “it’s time to take down the remaining portion of the Central Freeway, south of Market” and, in a letter to Caltrans, asked the agency to study the potential cost of removing the freeway. Separately, a group of San Franciscans is advocating for a car-free Embarcadero.
- Courts uphold Bay Area bridge toll increases that voters passed in 2018 regional measure (Local News Matters). A pot of $545 million destined for new projects in the Bay Area may soon be released from escrow after litigation over a 2018 ballot measure on bridge toll increases finally comes to an end. The California Supreme Court has let stand a decision from the state Court of Appeal in a case brought by the Howard Jarvis Taxpayers Association challenging toll increases on seven state-operated Bay Area bridges. Howard Jarvis was an anti-tax gadfly best known for his role in the 1978 passage of Proposition 13, which amended the California Constitution to limit tax on California real estate. HJTA advocates and frequently litigates against taxes.
- Ridge Route Preservation Organization – January / February 2023 Newsletter (RRPO). The storms of December 2022 and January 2023 have hit the roadway hard. Damage is fairly widespread with mudslides and rockslides being the order of the day. Reports given to us by members and the public have shown sections to be impassible by a standard automobile in many locations. From the Tumble Inn to Sandberg, there are numerous areas with flooding, mud, and rockslides. A few larger slides have been noted near Swede’s Cut and Serpentine Drive as well. At this time, it is not known if further damage has occurred between the Tumble Inn site and Swede’s Cut. It does not appear that the roadway has suffered similar damage to that of 2005, which saw the loss of three major sections of roadway. Weather permitting, we will be conducting a survey of the roadway over the weekend of February 4. As this winter is not yet over, further damage may still occur, likely in the form of landslides. We are hoping none are catastrophic, but years of minimal maintenance are taking their toll. CUTRR events will be scheduled later this year after this winter and spring calm down. Right now, we have a few targets for work regarding clearing drainages to prevent or mitigate flooding and sedimentation on the roadway. Stay tuned to our CUTRR pages for updates on those events.

- The Pinecate Rocks of US Route 101. The Pinecate Rocks are a geographical feature found along US Route 101 in western San Benito County in the Gabilan Range. The Pinecate Rocks are an often-cited location of numerous bandit holdups during the California Gold Rush. The Pinecate Rocks became part of US Route 101 when the highway was realigned past them during July 1932. Pictured above as the blog cover is a then two-lane US Route 101 passing by the Pinecate Rocks during 1932.
- Interstate 605. Interstate 605 is a 27.4-mile freeway located in the Los Angeles Metropolitain Area. Interstate 605 begins at Interstate 210 near Duarte and terminates at the Interstate 405/California State Route 22 junction to the south near the boundary to the city of Long Beach. Interstate 605 is known as the San Gabriel River Freeway and has three unconstructed miles which would extend it south to California State Route 1 near Seal Beach. Much of the corridor of Interstate 605 was built up from what was the original California State Route 35. The blog cover photo is taken from the July/August 1964 California Highways & Public Works which featured the initial segment of Interstate 605 to open between Whittier Boulevard and Peck Road
- Golden State Highways (version 3.0). Over the years Gribblenation has compiled hundreds of articles relating to highways in California along with copious amount of scenery the State has to offer. One thing that I’ve frequently received feedback on over the years is that it can be difficult to track down specific articles. The Golden State Highways and California Travel Directory aims to change this by making a go-to page for anything we feature related to California.
- California State Route 142. California State Route 142 as presently constructed is a twelve-mile State Highway located in Orange County and San Bernardino County. The constructed part of California State Route 142 begins in Yorba Linda at California State Route 90. From Yorba Linda the alignment of California State Route 142 follows Valenica Avenue and Carbon Canyon Road through the Chino Hills into San Bernardino County. Upon entering San Bernardino County, the constructed segment of California State Route 142 terminates at California State Route 71 via Chino Hills Parkway. California State Route 142 has a nine-mile unconstructed segment which would carry it from California State Route 71 to California State Route 210 in Upland. Depicted above is Carbon Canyon Road as seen in the January 1939 California Highways & Public Works when it was part of Legislative Route Number 177 prior to being renumbered California State Route 142.
- California State Route 159 (former California State Route 11 and US Route 66). California State Route 159 was a post 1964-Renumbering State Route which was designated over former segments of California State Route 11 and US Route 66. As originally defined California State Route 159 began at Interstate 5/US Route 99 at the Golden State Freeway in Los Angeles. California State Route 159 followed Figueroa Street, Colorado Boulevard and Linda Vista Avenue to the planned Foothill Freeway. California State Route 159 was truncated during 1965 to existing solely on Linda Vista Avenue where it remained until being relinquished during 1989. California State Route 159 was formally deleted from the State Highway System during 1992.
- Pre-1964 Legislative Route Number 141 in Bakersfield. Legislative Route Number 141 was a State Highway and western bypass of the city of Bakersfield which existed before the 1964 California State Highway Renumbering. Legislative Route Number 141 was brought into the State Highway System during 1933 and never was assigned a Sign State Route. At it’s fullest extent Legislative Route Number 141 began from US Route 99 at Golden State Avenue and followed Pierce Road, Rosedale Highway, Oak Street and Brundage Lane to US Route 99-399 at Union Avenue. Elements of Legislative Route Number 141 were incorporated into the US Route 99 and California State Route 58 bypasses of downtown Bakersfield. Above as the blog cover Legislative Route Number 141 via the then new Oak Street Overhead can be seen as it was during November 1939.
