Highway 1 is still sliding into the ocean
Caltrans has closed the bridge in the heart of Big Sur Village to vehicle traffic after it was discovered that one of the columns holding the bridge up is cracked due to erosion.
1964 flood – John Day Bridge
Making the country’s biggest arch bridge even bigger
I love the history of roads in the American West, and all the peculiarities you find along the way. It’s not hard to come across abandoned right of ways or older versions of current highways (like the old Columbia River Gorge Route 30).
It is rare to find a highway that is abandoned outright with no replacement in a parallel alignment. It’s even more rare to find an abandoned highway that still has significant structures intact! This is the case with the “Bridge to Nowhere” in the San Gabriel Mountians north of LA.
This beautiful open-spandrel deck arch was constructed as part of a planned route connecting the Azusa suburbs to the desert north of the mountains. The hillsides are unstable, and the road was deemed unbuildable after a flood wiped out a long section of it in 1938. The canyon walls has taken back a good portion of the old roadway, resulting is a bridge that is high and dry but impossible to drive to from either end.
The far side of the bridge seemingly ends in a rock talus, although I’m sure the road originally went for several more miles. Considering its age and lack of upkeep, the bridge appears to be in great shape. The site is currently privately owned, and is home to a bungee-jumping attraction.
