Rattlesnake Bar Suspension Bridge


Rattlesnake Bar was a small mining community located at the Placer County and El Dorado County line along the North Fork American River. During 1863 a wooden bridge was constructed at Rattlesnake Bar to facilitate access to quarry at Coral Caverns (now Alabaster Caverns). The original wooden span was replaced in 1865 with a suspension bridge. The 1865 suspension bridge would be open to traffic until 1954 when it was destroyed by an overloaded truck. The site of the Rattlesnake Bar Suspension Bridge became part of the Folsom Lake reservoir in 1955 and can still be viewed when the water is low.



The history of the Rattlesnake Bar Bridge

The history of the Rattlesnake Bar Bridge was featured in the September 1950 California Highways & Public Works Centennial edition.  The structure was notable during the 1850-1875 Pioneer Era due to it being one of the earliest suspension bridges constructed in the state.  Rattlesnake Bar was a small mining community located on the North Fork American River at what is now the El Dorado County and Placer County line.  During 1849-1850 a ferry across the North American River was placed at Rattlesnake Bar.  

This ferry at Rattlesnake Bar was replaced by a wooden bridge which was installed in 1863 following the devastating floods of 1862.  The wooden bridge was constructed to facilitate access to quarry at Coral Caverns (now Alabaster Caverns). The original wooden span was replaced in 1865 with the Rattlesnake Bar Suspension Bridge.  The article notes the Rattlesnake Bar Suspension Bridge was likely endangered due to the looming Folsom Lake reservoir project.  






The wooden Rattlesnake Bar Bridge was announced as being opened in the July 7, 1863, Sacramento Union (courtesy pitsenberger.com's page on the Rattlesnake Bar Bridge site).


The site of the Rattlesnake Bar Suspension Bridge can be seen south of Auburn at the North Fork American River on the 1882 Bancroft's Map of California.

Construction of the concrete gravity Folsom Dam began during 1951.  The Folsom Lake reservoir was planned as flood control measure in the Sacramento area.  The maximum extent of the reservoir was slated to consume the site of the Rattlesnake Bar Suspension Bridge.  The Rattlesnake Bar Suspension Bridge would be collapsed by an overloaded truck during 1954.  Given the structure was already in a state of condemnation Placer County and El Dorado County elected not to rebuild it.  

The collapsed Rattlesnake Bar Suspension Bridge can be seen in a photo posted by Mike Monahan on the Placer County History Facebook Page.

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. USends.com on US 60 endpoints 1934 State Highway Map Conversely US 70 was extended into California by 1934, it first appears on the 1936 State Highway Map. USends.com on US 70 endpoints 1936 State Highway Map When US 60 and US 70 were extended into California they both utilized what was Legislative Route Number 64 from the Arizona State Line west to Coachella Valley.  LRN 64 was part of the 1919 Third State Highway Bond Act routes.  The original definition of LRN 64 routed between Mecca in Blythe and wasn't extended to the Arizona State Line until 1931 acc...
