    This segment was LRN 55. It was originally signed as Route 5. It was defined in 1919.

    Pre-1963 Route 35

    1934 Rte 35Pre-1964 State Shield In 1934, Route 35 was signed along the route from Jct. Route 22 near Seal Beach to Jct. US 99 near West Covina via Santa Fe Springs. It ran from US60/US70/US99 (LRN 26; now I-10) along Puente Ave, Workman Mill Blvd, Norwalk Blvd, Pioneer Blvd, Norwalk Rd, and Los Alamitos Road to Route 22 (LRN 179) near Westminster. It was LRN 170, present-day I-605, defined in 1933, extended in 1957 and 1959.

    Route 35 General Notes

    According to Scott Rux in 2004, between Route 17 to Route 9, there are regular reassurance markers and postmiles. There are several Caltrans callboxes, all of which list the name of the highway in their identification. At the intersection of Bear Creek Rd and Skyline Blvd, there are directional signs indicating the continuation of Route 35, with the usual green miner's spade designations. At Summit Rd south and Mountain Charlie Rd (about 0.1 mile north of Route 17), the highway is only signed as "To Route 17". There are no Route 35 shields at the interchange with Route 17.

    Supposedly, some sections are one-lane wide, and appear to have been paved some time ago. A portion of Route 35 south of Route 9 is called the Goat Trail by CalTrans workers. Some portions of this route are maintained by the owners of the property near the road, and some portions are maintained by the County of Santa Clara or Santa Cruz County.

    In fact, Route 35 (Skyline Blvd.) follows the north boundary of Santa Cruz county (with both San Mateo and Santa Clara counties) for 20-30 miles, except that the boundary (defined by a mountain ridge) is so irregular that the road can't exactly follow it. The road wanders in and out of each county so frequently that most of the crossings are unmarked, and even Caltrans' county based "postmiles" aren't very accurate. At one point you're told that you're entering Santa Cruz county, and then about 0.4 mile later, you're told you're entering the city limits of Palo Alto. (Palo Alto is in Santa Clara county, and cities can't extend across county lines in California.) The southern portion of Route 35 between Route 9 and Route 17 is also almost totally unmarked, apparently because local residents tear down the signs.
    (Based on a posting by John David Galt)

    Repairs and Projects

    In February and March 2017, it was reported that major rains have caused significant damage to the highway. Specifically, Route 35 has been closed indefinitely after a portion of the roadway washed away W of Las Cumbres Road, near PM 035-SCl-10.47, according to the California Highway Patrol. A 200-foot section of the roadway in that section slid downhill more than 50 feet and is completely gone. It almost looks like someone scooped out a huge chunk of not only the road, but tons of earth that support the road bed. A permanent rebuild of the highway and stabilization of the hillside is estimated to cost more than $29.5 million. It has been reported that the road was eventually repaired.

    Part (2) was added in 1984 by Chapter 409.

    Pre 1964 Signage History Pre 1964 Signage History

    Before 1964, Route 35 was originally signed as Route 5. Before Route 280 was constructed, Route 5 began at the intersection of Route 9 (LRN 42) and Skyline, proceeded up to the junction of Route 92 (LRN 105), and then went over Crystal Springs Reservoir, and then turned north following the existing portion of Route 280 from the Route 92/I-280 interchange north to until where Skyline Blvd exits to the left. It was LRN 55. Route 5 was signed as part of the 1934 initial signage of routes. This was superseded in 1959 by LRN 237.

    According to Chris Sampang, after I-280 was built through the area in the 1970s, the Skyline Boulevard state highway (Route 35) was rerouted to I-280 between Route 92 and the current Route 35 semi-directional Y in San Bruno. However, a few portions of the old Skyline Boulevard still remain:

    1. In Millbrae, Skyline Boulevard between Larkspur Drive and Millbrae Avenue; the ramps leading into Skyline Boulevard from I-280/Route 35 may also be part of this.
    2. In Burlingame and Hillsborough, Skyline Boulevard from Trousdale Drive to Golf Course Drive
    3. In Hillsborough and San Mateo, including part of Golf Course Drive (which was named Skyline Boulevard as late as 1998, according to a CSAA Daly City/South San Francisco map) and Skyline Boulevard from Golf Course Drive south to Bunker Hill Drive. The portion of Skyline Boulevard from Bunker Hill Drive south to Route 92 was added back to the route in 1984 as the current Segment Two of the route—but is only signed as Route 35 going southbound; Route 35 northbound follows Route 92 east of the Skyline/Route 92 split and then I-280 north from Route 92 to past the Bunker Hill Drive interchange. North of Bunker Hill Drive, Route 35 is part of I-280 both northbound and southbound until the current Route 35/I-280 split.

    Also, according to Chris, around when I-280 was built, a couple of portions of Skyline Boulevard were bypassed in the San Bruno area. One starts at the junction of Glenview Drive and Ridgeway Avenue and goes south for about 600 feet and is essentially a cul-de-sac. Some old dirt right-of-way is visible south of the cul-de-sac itself between the end of the segment and Cambridge Lane. At Cambridge Lane, another segment of Skyline Boulevard begins. This lasts for about 900 feet southbound and then feeds into a short residential street; some more dirt right-of-way is visible through what are some residential backyards and into the current Route 35/I-280 merge. In Daly City, there is a "Skyline Drive" which begins at Westline Drive (possible former Route 1) in Pacifica and continues north to near Thornton State Beach. Although the part that parallels the Route 1 freeway routing to Westline Drive is most likely a newer construction, the rest of Skyline Drive parallels the current Skyline Boulevard completely. The north dead end seems to be pointing in a straight line to the old Route 1 stub in Thornton State Beach; thus Skyline and Route 1 may have merged here previous to the construction of the current 4 lane expressway and John Daly/Skyline junction. For more information, see Route 1. As of October 2006, the old intersection with Route 1 is no longer fenced off. In 2005, Daly City reopened this portion as Thornton Beach Vista. It's a small parking lot with a short trail leading to the bluff, with a few informational signs along the trail. One sign shows the alignment of old Route 1 pre-1957, and the old pavement can clearly be seen across a small gully that was formed by the storms of 1982 (that part is fenced off). There is no access to the actual State Park; for that you still need to take the freeway portion of Route 1 to the Manor Drive exit and go north on the frontage road.

    In 1963, this segment was defined as "Route 280 via Skyline Boulevard to Route 280 in San Francisco." In 1968, as part of the freeway reworking in San Francisco, the terminus was changed to "Route 1 in San Francisco", although this had no effect on the actual route, other than dropping a cosigning.

    Pre 1964 Signage History Pre 1964 Signage History

    This segment was signed as Route 5 between the initial signage of routes in 1934 and 1964. It was LRN 55, and was defined in 1919. See below for the original routing of signed Route 35.

    The portion between the Route 1 Freeway and John Daly Drive was cosigned with Route 1 between 1957 and 1967.

    Status Status

    Freeway currently exists from 1 mile south of jct with Route 1, to 1 mile north of jct of Route 1.

    In December 2017, the Caltrans Mile Marker noted that on Sloat Boulevard (Route 35 in San Francisco) they funded more of the Complete Streets Project: Caltrans in 2017 added more beacons and curb extensions, and extended bike lanes at this multi-phased project. Caltrans put a portion of Sloat Boulevard on a “road diet,” starting in 2012, shrinking the number of lanes from three to two, and adding bike lanes and improving crosswalks. In 2013, the city installed new crosswalk beacons at Forest View Drive.

    Naming Naming

    Portions of this route were named "Skyline Blvd" by Resolution Chapter 46 in 1919.

    Hanren ChangIn 2014, the legislature authorized via ACR 117 (Resolution Chapter 93, 7/15/14) the placement of an appropriate memorial plaque, funded by nonstate sources, within the right-of-way of Route 35 within the vicinity of the pedestrian beacon between Vale Avenue and Forest View Drive (~ SF 2.661) in San Francisco in memory of Hanren Chang. Hanren Chang was born in 1996 in Daly City, and grew up in the City and County of San Francisco. Hanren Chang attended Lowell High School in San Francisco and was an avid runner on the track and cross-country teams. Hanren Chang was loved and respected by her family and friends and was known as a selfless and loving person. On the evening of her birthday in 2013, Hanren Chang was the victim of a car accident that occurred under tragic circumstances involving a drunk driver on Route 35, also known as Sloat Boulevard, near Forest View Drive in San Francisco. Hanren Chang’s death has affected and touched the lives of many people, increased the call for pedestrian safety improvements along Route 35 in San Francisco, and heightened public awareness of the number of pedestrian fatalities in San Francisco. In fact, the intersection where Chang was killed has been made safer than before by the addition of a High-intensity Activity Activated Crosswalk Beacon. The beacon and other improved safety features were added to the busy crossing post the incident to reduce the chances of similar happenings in the future. The plaque honoring Chang was placed in the middle of the intersection.

Pre-1964 Legislative Route Pre-1964 Legislative Route

The route that would become LRN 35 was initially defined in 1907 by Chapter 117, by an act that authorized "...locating, surveying, and constructing a state highway connecting the present county road systems of any one or all of the counties of Trinity, Tehama, and Shasta with the road system of Humboldt County..." This provided the segment of the route between Peanut and Kuntz. In 1933, it was extended on both ends: "[LRN 1] near Alton to [LRN 35] near Kuntz" and "[LRN 35] near Peanut to [LRN 20] near Douglas City". Thus, by 1935, it was codified into the highway code as:

"[LRN 1] near Alton to [LRN 20] near Douglas City, passing near Kuntz and Peanut"

In 1957, a paragraph was added that gave priority to the funding of improving this route for any funding received. This language was adjusted further in 1959.

This routing was signed as Route 36 between Alton (US 101; LRN 1) and 4 mi SW of Peanut, where it met signed Route 3. At that point, it continued along the present-day Route 3 to Douglas City, where it terminated at US 299 (LRN 20).
