Depression is no laughing matter in psychology or in bridge work. The intersection of 130th Street and Torrence Avenue is being depressed 30 ft under the Norfolk Southern Railway tracks to eliminate conflicts with the at-grade rail line. Value planning resulted in raising the Chicago South Shore & South Bend commuter and freight railroad on a new 394-ft, 4.75 million-lb, double-track, ballasted-deck, steel through-truss bridge. The project team overcame many challenges by rolling the new bridge into place using self-propelled modular transporters.
