Hanson-Wilson provided engineering services to the Burlington Northern Santa Fe Railway Co. (BNSF) for the remodeling and rehabilitation of its Corwith Intermodal Yard freight facility in Chicago.

The facility occupies 317 acres in downtown Chicago and is bordered on three sides by heavily traveled urban streets. Efforts to conserve space take a high priority. Hanson-Wilson's improvements to increase access and traffic circulation, while more efficiently accommodating continually increasing intermodal traffic, include:

• Designing and constructing a bridge to carry three existing tracks over a new access
• Keeping approximately three tracks operating during bridge construction
• Designing and constructing four new 4,000-foot intermodal strip tracks
• Re-spacing two intermodal strip tracks
• Removing 14 general freight tracks
• Leveling the grade at the south end of the yard
• Reconfiguring tracks to permit 27 general freight tracks to converge, compensating for decreased capacity as a result of the new intermodal tracks
• Relocating and installing high mast lights to improve night visibility
• Replacing the asphalt pavement on Parking Lot 8 with a 19-inch concrete surface to support four loaded, stacked containers
• Demolishing a freight house and constructing a parking lot to create space to store empty chassis
  
• Expanding the third floor control tower at the 38th Street office.
