Sonoma County, California Bridges: Guerneville Bridge across the Russian River (2)

August 2014 (38.50096 Degrees, -122.99556 Degrees) Guerneville Bridge

Here's the view from the deck of the Guerneville Bridge. On the Historical Bridges Website they criticized the 'cyclone fencing,' which was erected when they converted the bridge to pedestrian use. I would imagine the lampposts were also put on the deck after the bridge was retired from 'active' service. You can appreciate how long these Parker truss spans are in this view looking down the bridge deck. The vertical clearance is 16 ft and so the truss must have about a 22 ft section depth, which provides a 180 ft length (with additional truss members at mid-span). The depth becomes higher and higher to increase the length until a truss span is no longer economical at about 600 ft.
