|August 2014 (38.1559 Degrees, -122.4082 Degrees) Sonoma Creek Bridge|
Several large rivers flow through Sonoma County before emptying into the Bay. On the southeast side of the county Sonoma Creek is crossed by the State Route 37 Bridge (23 0063). It's a 22 span precast girder bridge supported on precast pile extensions. The bridge was built in 1969 and retrofit in 2002. The pile extensions were okay for vertical loads but were weak laterally, particularly at the lap splice. Cast-in-Steel-Shell (CISS) pile shafts were placed by the exterior girders and big new bent caps were poured to connect everything together.
