Canadian Pacific Railway Catfish Creek Bridge


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.
