Dismantling a bridge

Removal of the old truss bridge continues as part of the Topaz Bridge replacement on U.S. 30 in District 5.

Pictured here is work to remove the old truss bridge in conjunction with the Topaz Bridge work on U.S. 30 in District 5. During this GARVEE-funded project, the existing two-lane, five-span, 379-foot long truss bridge, spanning the Portneuf River, Marsh Valley Canal, and Union Pacific Railroad, will be removed. In its place will be a 4-lane bridge that will be 613 feet long, and contains 3.5 million pounds of structural steel.

The old bridge was built shortly after World War II (1946-1947). The $18.1 million project is expected to wrap up by fall 2011.
