130th Street and Torrence Avenue Truss Move
3D Modeling, Planning, Survey | Illinois | Back
Challenge
This rail/roadway reconstruction project eliminated the at-grade crossings of the two Norfolk Southern main tracks with 130th Street and Torrence Avenue.
This was accomplished by lowering the profile of 130th Street and Torrence Avenue to fit under the two new bridges that now carry the railway.
Brainard Avenue was lowered and connected to 130th Street, at Torrence Avenue, to improve highway traffic flow for the 32,000 vehicles and 24 trains that pass through the crossing each day.
Exactly how this could be done posed an issue for designers and contractors alike.
Solution
Kapur provided modeling and visualization services to plan this move. We coordinated with contractors, the providers of the self-propelled mobile transporters (SPMTs), and engineers on site to accurately model the truss, existing roadways, proposed roadways, and the SPMTs in a 4D environment. This allowed us to depict the move through time to show pad build up, truss movement, and restoration after the move, all while tracking quantities and every piece of equipment.
Services Provided

Results
The plan to move the largest fully assembled truss bridge ever into place was completed without incident or injury. The 400-foot long, 67-foot high, 4.3-million-pound bridge over Torrence Avenue was rolled into place in late August of 2012.
