2016 Fall Mountain Trip Part 2; the Panamint Gap in California State Route 178

Picking up from where I left off in Part 1 I made my way up Trona Road to California State Route 178 east of Ridgecrest in northwest San Bernardino County.  Approaching Searles Valley there is a gap in CA 178 as the route was never built east through the Panamint Range.

CA 178 as it was originally envisioned ran east from US 101 through to CA 7 in Mojave Desert.  The original iteration of CA 178 can be seen on this 1938 California State Highway Map, by 1938 CA 7 at the eastern terminus of CA 178 had become part of US Route 6.

By 1947 Legislative Route Number 212 was adopted which was a planned route from the eastern terminus of CA 178 across the Panamint Range to CA 127.  More information can be found on CAhighways.org regarding LRN 212.

On the 1948 State Highway Map LRN 212 can be seen running east from US 6 to Trona where a planned route is shown crossing the Panamint Range.  LRN 212 resumes in Death Valley and is shown continuing east of CA 127 to the Nevada State Line.

By 1954 a new proposed alignment across the Panamint Range appears on the State Highway Map.

By the 1964 State Highway Renumbering LRN 212 became part of CA 178.

It is unlikely the gap in CA 178 over the Panamint Range will ever be complete.  Building a highway across the southern part of the Panamint Range would be costly and serve little in terms of moving traffic.  The defacto connection between the Panamint Gap in CA 178 is largely served by roads through Panamint Valley, CA 190 and Badwater Road in Death Valley National Park.

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l

Mines Road

Mines Road is an approximately twenty-eight-mile highway located in the rural parts of the Diablo Range east of the San Francisco Bay Area.  Mines Road begins in San Antonio Valley in Santa Clara County and terminates at Tesla Road near Livermore of Alameda County.  The highway essentially is a modern overlay of the 1840s Mexican haul trail up Arroyo Mocho known as La Vereda del Monte.  The modern corridor of Mines Road took shape in the early twentieth century following development of San Antonio Valley amid a magnesite mining boom.  Part 1; the history of Mines Road Modern Mines Road partially overlays the historic corridor used by La Vereda del Monte (Mountain Trail).  La Vereda del Monte was part of a remote overland route through the Diablo Range primarily used to drive cattle from Alta California to Sonora.  The trail was most heavily used during the latter days of Alta California during the 1840s. La Vereda del Monte originated at Point of Timber between modern day Byron and Bre

Interstate 210 the Foothill Freeway

The combined Interstate 210/California State Route 210 corridor of the Foothill Freeway is approximately 85.31-miles.  The Interstate 210/California State Route 210 corridor begins at Interstate 5 at the northern outskirts of Los Angeles and travels east to Interstate 10 in Redlands of San Bernardino County.  Interstate 210 is presently signed on the 44.9-mile segment of the Foothill Freeway between Interstate 5 and California State Route 57.  California State Route 210 makes up the remaining 40.41 miles of the Foothill Freeway east to Interstate 10.  Interstate 210 is still classified by the Federal Highway Administration as existing on what is now signed as California State Route 57 from San Dimas south to Interstate 10.  The focus of this blog will mostly be on the history of Interstate 210 segment of the Foothill Freeway.   Part 1; the history of Interstate 210 and California State Route 210 Interstate 210 (I-210) was approved as a chargeable Interstate during September of
