Los Angeles County, California Bridges: Fourth Street Bridge across the Los Angeles River (1)

August 2013 (34.04167 Degrees, -118.22694 Degrees) 4th Street Bridge

Standing on the deck of the Sixth Street Bridge and looking north at the Fourth Street Bridge. It's a nice, clear day (for Los Angeles) and we can see the Verdugo Mountains in the background.

The Fourth Street Bridge is a long viaduct that was built in 1930 and crosses the same obstacles as the Sixth Street Bridge. However, the Fourth Street Bridge has an open spandrel concrete arch over the L.A. River and it was seismically retrofit in 1995. Even after the retrofit though, it remains structurally deficient and with a deck in 'Poor' condition. A question that bridge owners need to address is if it makes economic sense to retrofit a bridge in poor condition?
