Yolo County, California Bridges: County Road 25 Road Bridge across Cottonwood Slough

July 2013 (38.65000 Degrees, -122.04889 Degrees) Cottonwood Slough Bridge

Moving north of Winters onto County Road 25 and the Cottonwood Slough Bridge (22C0075). It's a 108 ft long single span truss bridge that was built in 1932. Cottonwood Slough meanders back and forth so many times across CR25 that there are a half dozen Cottonwood Slough Bridges. This bridge sits on steel bearings bolted to little concrete abutments on each side of the slough.

Its a Pratt through truss that was rehabilitated in 1956. It's in fair condition with an S.R. of 44.3% and only a 12 ft wide deck. However, it has a surprising 16 ft vertical clearance above the deck and carries about 90 vehicles a day on this lonely country road.

Note the big floor beams sticking way out beyond the deck. This bridge must have been originally designed for a wider deck! The bottom chord includes a tension member at the bottom of the floor beams and double eyebars at the top of the floor beams. This a nice little bridge!

Look how dry Cottonwood Slough is in July (and surrounded by poison oak!).
