text: Kraemer replaced the 117-year-old steel thru truss and eight timber span Catfish Creek Bridge with a four-span, 42-inch double cell box beam and a TPG span bridge. The old bridge was floated out on barges and demolished off site. Jacking towers were used to lift the bridge off the existing bridge abutments. Access to the site was limited to rail, therefore the bridge was erected off site and transported to the site by rail. The main span switch-out was completed in 10 hours, which included floating out a 175-foot thru truss, demolition of four timber spans, placement of two spans of 42-inch double cell box beams, replacement of 250 feet of track and ties on the new bridge, and raising the approach grade ballast four inches.
