Project Scope
The project included the reconfiguration of the existing typical diamond interchange at I-88 into a Diverging Diamond Interchange, the first interchange of its kind in northeastern Illinois. As well as removing and replacing the Illinois Route 59 bridge over the Ronald Reagan Memorial Tollway (I-88) interchange with two new independent bridge structures.
Awards:

- 2016 APWA Chicago Metro Chapter’s Project of the Year Award
"OMEGA had the opportunity to work on an innovative diverging diamond interchange which completely reconfigured the alignment of IL-59 & I-88 in Naperville, IL. This unique interchange was the first of its kind in the Chicago area. The diverging diamond not only increased safety by eliminating opposing left turns, but also increased capacity by changing the traffic signals to a 2-phase cycle. OMEGA was proud to be part of the team that successfully implemented the project on time, winning a few awards along the way."
