Big Sur Slide Spectactular Part 5; New Pfeiffer Canyon Bridge Opens

On the 19th I had an opportunity to drive down from Monterey to Big Sur to the recently completed new Pfeiffer Canyon Bridge on California State Route 1.  Given Pfeiffer Canyon just reopened on October the 13th, the CA 1 BGS sign at the Carmel River was changed to reflect that fact that Lucia as far south as Gorda can now be reached by car.


Rather than re-post all the photos of Big Sur along CA 1 like I have many times this year I'll just refer anyone interested in viewing them to my Flickr page:

I think most people who view this blog really just want to see the new Pfeiffer Canyon Bridge.  My approach was southbound past some still active Caltrans crews.






There was a handy pull-off of the south side of the new bridge which allowed me to get a good look at the structure.



The lanes on the new Pfeiffer Canyon Bridge are 12 feet wide with 5 feet shoulders.  The new bridge time stamp is easily reached with the extra wide shoulders.





The previous Pfeiffer Canyon Bridge was constructed by 1968 and was a concrete box girder design.  The 1968 bridge replaced a wooden road bridge which likely was in place when CA 1 was being built in the Big Sur region in the 1930s.

Back in February of this year the 1968 Pfeiffer Canyon Bridge was damaged in mudslides.  Specifically the slides damaged the support pillars which necessitated Caltrans declaring the bridge condemned on February the 20th.  The new bridge design is a single steel span which should in theory be a much better design to clear the slide zone in Pfeiffer Canyon.  The San Francisco Gate has a partial time lapse of the new Pfeiffer Canyon Bridge construction.

CA 1 through Big Sur won't be completely open until the Mud Creek Slide zone is rebuilt.  Current projections have the entire highway being reopened by summer of 2018.  At present moment CA 1 can be used south from Monterey along the Nacimiento-Fergusson Road to reach County Route G14.

California State Route 232

This past month I drove the entirety of California State Route 232 in Ventura County. CA 232 is an approximately 4 miles State Highway aligned on Vineland Avenye which begins near Saticoy at CA 118 and traverses southwest to US Route 101 in Oxnard.  The alignment of CA 232 was first adopted into the State Highway System in 1933 as Legislative Route Number 154 according to CAhighways.org. CAhighways.org on LRN 154 As originally defined LRN 154 was aligned from LRN 9 (future CA 118) southwest to LRN 2/US 101 in El Rio.  This configuration of LRN 154 between CA 118/LRN 9 and US 101/LRN 2 can be seen on the 1935 California Division of Highways Map of Ventura County. 1935 Ventura County Highway Map According to CAhighways.org the route of LRN 154 was extended west from US 101/LRN 2 to US 101A/LRN 60 in 1951.  Unfortunately State Highway Maps do not show this extension due to it being extremely small. During the 1964 State Highway Renumbering LRN 154 was assigned CA 232.  Of n

Former US Route 101 and California State Route 1 in San Luis Obispo

Originally US Route 101 upon descending Cuesta Pass southbound entered the City of San Luis Obispo via Monterey Street.  From Monterey Street US Route 101 utilized Santa Rosa Street and Higuera Street southbound through downtown San Luis Obispo.  Upon departing downtown San Luis Obispo US Route 101 would have stayed on Higuera Street southward towards Pismo Beach and Arroyo Grande.  Notably; beginning in 1934 US Route 101 picked up California State Route 1 at the intersection of Monterey Street/Santa Rosa Street where the two would multiplex to Pismo Beach.  Pictured below is the 1 935 Division of Highways Map of San Luis Obispo County depicting the original alignments of US Route 101 and California State Route 1 in the City of San Luis Obispo.   Part 1; the history of US Route 1 and California State Route 1 in San Luis Obispo San Luis Obispo lies at the bottom of the Cuesta Pass (also known as the Cuesta Grade) which has made it favored corridor of travel for centuries.  Cuesta Pass

Former California State Route 1 over Old Pedro Mountain Road

California State Route 1 in western San Mateo County traverses the Montara Mountain spur of the Santa Cruz Mountains.  In modern times California State Route 1 passes through Montara Mountain via the Tom Lantos Tunnels and the highway is traditionally associated with Devils Slide.  Although Devils Slide carries an infamous legacy due it being prone landslides it pales in comparison to the alignment California State Route 1 carried prior to November 1937 over Old Pedro Mountain Road.   Old Pedro Mountain Road opened to traffic in 1915 and is considered one of the first major asphalted highways in California.  Old Pedro Mountain Road clambers over a grade from Montara towards Pacifica via the 922 foot high Saddle Pass.  Pictured above an overlook of Old Pedro Mountain Road facing southward towards Montara as it appears today.  Pictured below it the same view during June 1937 when it was part of the original alignment of California State Route 1.  Today Old Pedro Mountain sits abandoned a
