Projects > Illinois Tollway Program Management


SE3 is a sub-consultant to AECOM on the Central Tri-State Design Corridor Manager (DCM) team for the Illinois Tollway. The Illinois Tollway's “Move Illinois” program is a 15-year, $12 billion capital plan designed to help increase mobility and relieve congestion in northern Illinois. As a part of Move Illinois, the DCM team oversees $4 billion worth of Central Tri-State reconstruction, encompassing 19 individual design contracts for developing more than 50 construction contracts. Along with our DCM responsibilities, SE3 provides design support to 6 contracts in the Central Tri-State corridor. SE3 contributes to the team by filling key coordinator roles with responsibilities covering the entire project corridor for the DCM, and by being a trusted design partner and technical resource to all our project teams. Our services in support of this project are multi-faceted and span several disciplines.
