CREATE 75th CIP/B9 Projects

As part of a general engineering consulting contract with CSX Transportation (CSXT), STV provided civil, electrical, and track engineering design; construction management services; and inspection services of CSXT’s 75th Street Corridor Improvement Project in Chicago. The goal of this program is to create a new double-track connection between the CSXT’s Beltway and East-West corridors, which will allow trains to increase speeds to 25 mph.

The firm also designed main line crossovers that will replace an existing connection and increase track capacity in Summit Argo, IL. To support a nearby industrial facility, STV provided design improvements to the yard, including the realignment of switching lead tracks and the installation of new yard tracks.

Both of these locations’ improvements are part of the larger Chicago Region Environmental and Transportation Efficiency (CREATE) Program, which is investing billions of dollars in improvements for passenger and freight rail infrastructure in the Midwest.
