Napa County, California Bridges: State Route 128 across Soda Creek

December 2013 (38.50167 Degrees, -122.25667 Degrees) Soda Creek Bridge

I drove past Sage Creek Bridge on SR 128 (a concrete arch bridge built in 1945) on my way to today's structure, the Soda Creek Bridge. Fortunately, Craig Philpott photographed Sage Creek for the Bridgehunter Website. Soda Creek Bridge is on a high skew under State Route 128. In a previous blog I wondered how one builds a skewed arch bridge. In this case you just build the arch longer, but at an angle to the road.

The Soda Creek Bridge is only 16 ft long and it was built in 1910. State Route 128 got widened in 1955 and I noticed that the bridge has a large corrugated metal arch culvert on the east side that was used for the widening. It looks like it was used as a form since I can see concrete above the metal.
