|March 2013 (38.39299 Degrees, -120.80045 Degrees) Sutter Creek Footbridge|
We avoided the State Route 49 Cutoff and took Old California 49 into the tourist town of Sutter Creek. Just east of town are a couple of tubular steel pedestrian bridges over Sutter Creek. They are Pratt pony truss bridges that use the railing as structural members to support the bridge. The bridge in today's blog has a plaque dedicated to Anne Conrardy, which suggests this bridge was at least partially constructed with funds from Anne's family.
Anne's bridge has a high camber, so it must be supported on strong foundations to resist the longitudinal force of the bowed superstructure. It has a grated steel deck to allow for drainage. The steel looks brown and is probably a type of Corten (weathering) steel.
These bridges look like they would be easy to fabricate in a factory or at the bridge site. A crane could pick up the bridge and set it on a pair of well supported abutments.
