Central Tri-State Tollway Master Plan

Central Tri-State Tollway Master Plan

TranSystems was initially selected by the Illinois State Toll Highway Authority (Tollway) to perform Master Planning services and Advanced Engineering Studies (30% concept design) for 12 miles of the Tri-State Tollway (I-294), located between 95th Street and Cermak Road in Cook County, Illinois. This project was part of the Tollway’s ongoing 15-year, $14 billion capital program, Move Illinois: The Illinois Tollway Driving the Future. As part of the project, TranSystems evaluated the alternatives identified in the Corridor Concept Study, including potential widening, for proposed improvements to the most important and most congested facility within the Tollway system.

During the Master Planning phase, TranSystems developed roadway geometrics for multiple alternatives, including evaluation of impacts to cost, property, utilities and schedule.
TranSystems advanced the engineering design from the Master Planning level to concept (30%) level design as part of the Advanced Engineering Studies. More detailed drawings were developed to allow the Tollway to begin long lead-time activities such as property acquisition and utility relocation.

Subsequent to completion of the Master Plan and Advanced Engineering Studies, TranSystems was again selected by the Tollway to continue in the overall development of the future Central Tri-State Tollway Corridor. TranSystems applied many unique and innovative engineering solutions in developing the vision for the future Central Tri-State Tollway Corridor.  As a Design Section Engineer (DSE), TranSystems performed Phase II engineering services, consisting of the preparation of contract plans, specifications, estimates, and project-related permits for a 3.7-mile long segment of I-294. This design section is one of the most critical segments to the success of the overall Central Tri-State Corridor improvement.
