Los Angeles County, California Bridges: I-710 Bridge across the Los Angeles River

August 1999 (33.9358 Degrees, -118.1752 Degrees) Los Angeles River Bridges

After walking past the UPRR Bridge I came to the I-710 (Long Beach Freeway) Bridge (53 0828). It's a four span steel girder bridge on an opposite skew to the UPRR Bridge (seen in the background of today's photo). It was built in 1955 and retrofitted for earthquakes in 1996. The bridge has tall narrow pier walls but the ends of the girders are connected to hangers cantilevered past the pier.

It seems like city engineers get the more exciting bridge projects while state engineers end up with more mundane highway bridges. A problem with steel bridges on skews is that the cross-bracing sometimes doesn't meet from girder to girder causing fatigue cracks over time.
