OMEGA provided construction engineering services for this $37 million, complete interchange, reconstruction project on the Jane Addams Memorial Tollway. This was the first project to get underway as part of the Illinois Tollway’s $12 billion capital program, Move Illinois: The Illinois Tollway Driving the Future. This project was constructed on an aggressive schedule to avoid any impact to the ongoing 62-mile-long Jane Addams Tollway mainline reconstruction.

Project Scope

This complex project involved removal of the existing outdated bridge structure and partial access interchange , constructing a new seven lane wide bridge over I-90, and constructing new all electronic I-PASS toll plazas servicing six new ramps, allowing full access in all directions. 

As the Illinois Tollway’s first “green interchange,” the project also included several new environmentally friendly initiatives including: 

  • Geothermal heating and cooling for the plaza buildings 
  • Reflective roofs 
  • Trellised vegetation at the buildings 
  • Bioswales 
  • Permeable ramp shoulder pavement
