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:

Madera County Road 607 and the Stockton-Los Angeles Road

Madera County Road 607 is an approximately seven-mile rural unsurfaced highway which spans from Road 600 near Raymond west to Road 29.   Road 607 west from Raymond Road Cemetery (established in 1905) is part of the Stockton-Los Angeles Road corridor surveyed in 1853. The corridor lies in the gap between Fresno Crossing at the Fresno River west to Newton's Crossing at the Chowchilla River. The Buchanan Copper Mine would be along what is now Road 607 in the namesake Buchanan Hollow during July 1863. The Buchanan Mine is thought to have once had a population of between 1,000-1,500 residents by the early 1870s. Copper prices would decline in the decade after the Civil War and much of the activity at Buchanan shifted towards cattle ranching. The last businesses in the community would shutter during World War II and it is now a true ghost town.

Old US Route 60/70 through Hell (Chuckwall Valley Road and Ragsdale Road)

Back in 2016 I explored some of the derelict roadways of the Sonoran Desert of Riverside County which were part of US Route 60/70; Chuckwalla Valley Road and Ragsdale Road. US 60 and US 70 were not part of the original run of US Routes in California.  According to USends.com US 60 was extended into California by 1932.  US 60 doesn't appear on the California State Highway Map until the 1934 edition.
