Sacramento County, California Bridges: Rancho Murieta Footbridge across the Cosumnes River (4)

March 2013 (38.49477 Degrees, -121.08421 Degrees) Cosumnes River Bridge

A few more photos of the Cosumnes River Footbridge. When I first saw this bridge from a distance, I just assumed I was looking at an old steel truss.

The bridge portals are unadorned vertical steel I girders with a Glulam top chord. The deck is 12 ft wide and composed of 2-1/2 inch thick Glulam panels. I'm not sure about the vertical clearance. The bridge had to be designed for a 10 kip maintenance vehicle. I wonder if it controlled the design?

A look at the underside of the bridge deck, which is supported by Glulam floor beams and stringers. Steel rods provide lateral stability at the top and bottom chords. The superstructure was designed by Western Wood Structures, the substructure was designed by Quincy Engineering, and the bridge was built by Viking Contractors. Western Wood Structures has a nice website with a description of this bridge.
