Napa County, California Bridges: Sanitarium Road Bridge across Canon Creek

December 2013 (38.53617 Degrees, -122.47426 Degrees) Sanitarium Road Bridge
The Seventh Day Adventists have a large community at the north end of Napa Valley. We passed a very nice Seventh Day Adventist Hospital on Sanitarium Road where we also found today's bridge.
The Sanitarium Road Bridge across Canon Creek is a small closed spandrel arch bridge, really more of a culvert by Caltrans' standards. Craig Philpott took a nice photo of Canon Creek at flood stage for the Bridgehunter Website. We can see the left over debris from the flood in today's photos. 

The problem with these little bridges and with closed spandrel arch bridges in general is that their shape restricts the amount of water and debris that can pass through, which often results in flooding. This is why Napa County eventually had to replace many of their historic arch bridges.
