McCullough Construction Replacing Swift Creek Bridge By Irwin Rapoport

Crews from McCullough Construction Inc. are eager to complete the California Department of Transportation’s (Caltrans) $14 million replacement of the Swift Creek Bridge on State Route 3 in Trinity County, a project that is 90 percent complete. The work is anticipated to be complete in late spring or summer. The initiative is replacing the existing bridge, a 168-ft. long, two-span, reinforced concrete T-girder bridge with seat type abutments and a pier wall supported on spread footings with one-lane in each direction. The work is taking place approximately 1 mi. south of Trinity Center, to a halfmile north of Trinity Center along SR 3. The original bridge was constructed in 1957. The new structure is a two-span, precast/prestressed, wide flange concrete girder bridge with the same number of lanes and two standard 8-ft. wide shoulders. California ST-70S bridge rail that is see through and side mounted is being installed. General roadway paving improvements along the route are being executed: standard width 8-ft.-wide shoulders; increased horizontal curve radius from 350 ft. to 587 ft.; and a raised roadway profile.

McCullough Construction is replacing the Swift Creek Bridge on State Route 3 in Trinity County, a structure that was originally constructed in 1957.

The Swift Creek Bridge is being replaced because the old bridge was originally built in 1957 and endured decades of freeze-thaw wear and tear.
