Routing Routing

Rte 127From Route 15 near Baker to the Nevada state line via the vicinity of Death Valley Junction.

Post 1964 Signage History Post 1964 Signage History

This routing is unchanged from its 1963 definition.

As of 2018, Route 127 was a two-lane undivided highway on generally level terrain set in a rural, desert landscape. The lanes are 12 feet wide in each direction with 1-foot wide shoulders. The opposing traffic along the majority of this segment is separated by double-yellow lines. The elevation ranges from approximately 587-feet to 594-feet above mean sea level from south to north. There are no utilities, airports, housing, or railroads in the vicinity of the project. The route is functionally classified as a Rural Minor Arterial, connecting southeastern California to Nevada and other rural highways. The route is part of the Interregional Road System (IRRS) and is included as a Terminal Access Route within the Surface Transportation Assistance Act (STAA) Network. Route 127 serves local, interregional, recreational, and goods movement traffic while providing access to Death Valley National Park and other recreational lands.

Pre 1964 Signage History Pre 1964 Signage History

In 1934, Route 127 was signed from Jct. US 91 at Baker to the California-Nevada State Line near Death Valley Junction. It was LRN 127 between Baker and Death Valley Junction (junction Route 190), and LRN 128 from Death Valley Junction to the Nevada state line. Both routes were defined in 1933. This is one of those rare routes (Route 58 is another) where the pre-1963 legislative number and the signed number are the same.

Caltrans characterized the history of the route as follows in a recent EIR:
(Source: Route 127 Rumble Strips Initial Study and [Proposed] MND, April 2018)

Route 127 is a north-south highway that begins at I-15 near the community of Baker, continues north past the San Bernardino County line into Inyo County, and ends at the California-Nevada State border at Nevada 373. Route 127 is eligible for the State Scenic Highway System; however, it has not been designated by Caltrans as a scenic highway. In 1933, Route 127 was added to the State Highway System and went from I-15 in Baker to Death Valley Junction; Route 128 during this time continued from there to the Nevada state line. In the state highway renumbering of 1964, Route 127 was re-defined from I-15 to the Nevada state line and has remained unchanged since.

Widening and Rumble Strips Project | 08-SBd-127 28.0/R28.5

Rte 127 RumblestripsIn January 2018, it was reported that Caltrans was planning to widen the shoulders of Route 127 in Fall 2018 and to install rumble strips between PM SBD 28.0 and SBD 28.5. Caltrans plans to construct 8-foot-wide shoulders and install 12-inch-wide rumble strips along each direction and the centerline of the highway in an unincorporated area of San Bernardino County. Light grading will also be performed to accommodate shoulder widening. The safety project is scheduled to be completed in early 2019.

In April 2018, Caltrans posted the Initial Study / with [Proposed] Mitigated Negative Declaration for the Route 127 Shoulder Widening and Rumble Strips Project, 08-SBD-127 (PM 28.0/28.5). Caltrans proposes to construct, in both directions, eight-foot shoulders and install in-ground rumble strips (12 inches wide), along the centerline and shoulders on Route 127 from Post Mile (PM) 28.0 to PM 28.5, located 28 miles north of the nearest community of Baker in San Bernardino County. These improvements would occur from the beginning of curve to the end of curve, and transitions. The granting of a 40-foot easement from the centerline (in both directions) of undeveloped U.S. Bureau of Land Management (BLM) land is anticipated.

In August 2018, the CTC approved $1,339,000 in SHOPP funding for San Bernardino 08-SBd-127 28.0/R28.5 Route 127 Near Baker, 28.0 miles north of Route 15 to 1.2 miles south of Saratoga Springs Road. Outcome/Output: Construct shoulders and install ground-in rumble strips. This will reduce the number and severity of collisions.

In August 2018, the CTC approved for future consideration of funding the following project for which a Mitigated Negative Declaration (MND) has been completed: Route 127 in San Bernardino County (08-SBd-127, PM 28.0/28.5). Construct roadway improvements on a portion of Route 127 near the town of Baker. (PPNO 0216F) This project is located near Baker, south of Saratoga Springs Road in San Bernardino County The project proposes to widen and construct paved shoulders and ground-in rumble strips on Route 127. The project proposes to reduce the number and severity of cross centerline and runoff road type collisions. The proposed project is currently estimated to cost approximately $2.5 million in capital and right of way. The project is fully funded and is currently programmed in the 2016 SHOPP for approximately $2.5 million which includes Construction (capital and support) and Right-of-Way (capital and support). The project is estimated to begin construction in 2019. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2016 SHOPP.

Statistics Statistics

Overall statistics for Route 127:

Pre-1964 Legislative Route Pre-1964 Legislative Route

In 1933, Chapter 767 added the following routes to the state highway system: "

In 1935, LRN 127 was added to the highway code with the following definition, which covered most of these routes:

  1. [LRN 4] near Tipton, via Porterville and Camp Nelson to [LRN 23] near Lone Pine
  2. [LRN 23] near Lone Pine to Death Valley
  3. [LRN 31] to Death Valley

The "connection to the California-Nevada State Line" was added as part of LRN 128.

In 1959, Chapter 1355 rerouted segment (a) combining it with (c), and clarified (b), giving:

  1. [LRN 4] near Tipton to [LRN 31] near Baker via the vicinity of Porterville, Camp Nelson, Olancha, Death Valley, and Death Valley Junction.
  2. From [LRN 23] near Lone Pine to a junction with the route described in part (a).

This was signed as follows:

  1. From Route 99 (LRN 4) near Tipton to I-15 (US 91, US 466, LRN 31) near Baker via the vicinity of Porterville, Camp Nelson, Olancha, Death Valley, and Death Valley Junction.

    This segment was signed, along the constructed portions, as Route 190 to Death Valley Junction, and as Route 127 from Death Valley Junction to I-15. (and dates back to the initial 1934 signage of state routes).

  2. From US 395 (LRN 23) near Lone Pine to a junction with the route described in part (1).

    This segment appears to have been unsigned; it is present-day Route 136.

Note: The Gribblenation Blog on Route 136 (Tom Fearer) has a bit more information on the routings of LRN 127 and the timing of acquisitions. The following is a quote from the blog, in case the page disappears (module some terminology adjustments):

The routing of Route 136 was part of Legislative Route Number (LRN) 127. LRN 127 was adopted in 1933 and generally was signed as Route 190 through all segments of the highway. The original routing of LRN 127 can be seen on the California Division Highways Map of Inyo County. Interestingly LRN 127 is shown running on Horseshow Meadow Road to Lonepine and has a gap from the yet obtained Eichbaum Toll Road in Panamint Valley.

By 1938 the state had obtained the right-of-way for the Eichbaum Toll Road. Route 190 is shown running from US 99 east to Quaking Aspen in the Sierras. A proposed route through the Sierras via Kern Canyon to Horseshoe Meadow is shown. Route 190 is shown on the current routing of Route 136.

By 1960 a new proposed alignment of Route 190 from Quaking Aspen to Olancha was adopted. This new alignment included the modern segment of Route 190 east of US 395 to Route 136.

By 1964 the California Highway Renumbering had occurred and a new number of 136 was assigned to the highway between Lone Pine to the modern Route 190 junction at Owens Lake.
