How many Truss bridges does Sacramento have? The Fair Oaks Bridge is a Truss bridge, as is the "I" Street Bridge (see photo). According to the Sacramento Bee*, however, Sacramento County's only questionable spans are two, and neither is a Truss bridge: "1923 'bascule' bridge that opens for ship traffic on Highway 160 over the Sacramento River, and a 1949 'lift' bridge that also opens to ship traffic on Highway 160 over Three Mile Slough." Their inspection comes as part of a national alert and will be supervised by Caltrans.
*"'Deficient' but unfixed 1990 probe saw flaw; Caltrans checking similar spans Immediate inspections in California," by Carrie Peyton, et al. Sacramento Bee, August 3, 2007, section A1.
