Commodore Schuyler F. Heim Bridge
From Wikipedia, the free encyclopedia
The Commodore Schuyler F. Heim Bridge is a vertical-lift bridge in the Port of Los Angeles.
The bridge, constructed in 1949, allows California State Route 103 to cross over the Cerritos Channel. It is the largest vertical-lift bridge on the West Coast. The deck of the bridge is an open grid to decrease weight and ease lifting of the bridge to allow ship traffic to pass underneath.
Highway 103 is heavily used by trucks to bypass part of the crowded 710 freeway. The large amount of heavy truck traffic over the bridge, the deck is subject to excessive wear. The deck was completely replaced in 1997 but was still under extreme distress. The California Department of Transportation installed eight experimental fiber reinforced polymer panels and attached sensors to test stress, load bearing, and temperature variations of the panels to determine their effectiveness as a permanent replacement.[1]
A proposal has been made to replace the Schuyler Heim Bridge with a four-lane fixed-span bridge by 2011.[2]
