Cave Rock Tunnel; US Route 50 Lake Tahoe

Back in 2016 I visited the Cave Rock Tunnel on US Route 50 on the eastern shore of Lake Tahoe in Douglas County, Nevada.

The Cave Rock Tunnel is a dual-bore tunnel through a rock formation of the same name. The Cave Rock Tunnel was intended as a replacement of the original alignment of US 50 which was routed on the South Branch of the Lincoln Highway. Prior to the Cave Rock Tunnel being built traffic had to use a one-lane swing bridge located on the edge of Cave Rock which dated back to 1863. Ruins of the bridge abutment are still present on the western section of Cave Rock overlooking Lake Tahoe.

The 1931 Cave Rock Tunnel bore is 157 feet in length and presently serves US 50 West traffic. The eastbound Cave Rock Tunnel much longer at 410 feet in length and was completed in 1957. When I arrived at Cave Rock in 2016 the 1931 bore was under going a seismic retrofit which included a concrete liner and a rock shed on the end of the tunnel. In the photo below US 50 traffic is shown two-way via the 1957 Cave Rock bore.

The link below shows a photo of the original Cave Rock alignment of US 50 next to the 1931 bore.

I was provided with a link by NE2 on AAroads for the book; Cave Rock: Climbers, Courts, and a Washoe Indian Scared Place. On page 40 a picture of the Cave Rock Bridge can be seen:

I-40 rockslide uncovers old debates on highway

The Asheville Citizen-Times continues to do a great job covering all the angles of the Interstate 40 Haywood County rock slide. An article in Sunday's edition provides a strong historical perspective on how the Pigeon River routing of Interstate 40 came about. And perhaps most strikingly, in an article that ran just prior to the highway's opening in the fall of 1968, how engineers from both Tennessee and North Carolina warned "...that slides would probably be a major problem along the route for many years." On February 12, 1969, not long after the Interstate opened, the first rock slide that would close I-40 occurred. Like many other Interstates within North Carolina, Interstate 40 through the mountains has a history prior to formation of the Interstate Highway System and was also a heated political battle between local communities. The discussion for a road that would eventually become Interstate 40 dates back to the 1940's as the idea for interregional high

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

Former California State Route 41 past Bates Station

When California State Route 41 was commissioned during August 1934 it was aligned along the then existing Fresno-Yosemite Road north of the San Joaquin River. Within the Sierra Nevada foothills of Madera County, the original highway alignment ran past Bates Station via what is now Madera County Road 209, part of eastern Road 406 and Road 207. Bates Station was a stage station plotted during the early 1880s at what was the intersection of the Coarsegold Road and Stockton-Los Angeles Road. The modern alignment bypassing Bates Station to the east would be reopened to traffic during late 1939. Part 1; the history of California State Route 41 past Bates Station Bates Station was featured as one of the many 1875-1899 Madera County era towns in the May 21, 1968, Madera Tribune . Post Office Service at Bates Station is noted to have been established on November 23, 1883 and ran continuously until October 31, 1903. The postal name was sourced from Bates Station owner/operator George Ba
