High Speed Rail Corridor


Illinois Department of Transportation


Chicago, Illinois to St. Louis, Missouri
The Illinois Department of Transportation (IDOT) was chosen to upgrade the existing Amtrak route from Chicago to St. Louis to provide for higher speed passenger train service.

Project Scope

The track speed will increase from 79 mph to 110 mph for passenger trains. The goal of the project was to decrease travel time from Chicago to St. Louis and to provide short and long term economic stimulus. This project was funded by the American Recovery and Reinvestment Act (ARRA). The Union Pacific Railroad was the owner of the right of way and essentially served as the General Contractor for the project.


OMEGA provided construction engineering services throughout the Chicago/St. Louis rail corridor. This portion of the project consisted of inspection, supervision, construction layout, material testing, field inspection for highway/railroad grade crossings, grade separation, approach roadway reconstruction or rehabilitation, earth excavation and embankment construction, and bridge rehabilitation or construction.
