Major work includes reconstruction of approximately 80 bridges, including the Mile Long Bridge, Burlington Northern Santa Fe (BNSF) bridge over I-294, the I-294/I-290/I-88 interchange and I-294/I-55 interchange. As Owner’s Representative, OMEGA is serving as the single point of contact for the Tollway throughout the design and construction and reporting directly to Tollway executives.
Mile Long Bridge
The Mile Long Bridge is a critical piece of infrastructure on the Illinois Tollway Central Tri-State Tollway (I-294) Corridor as it carries drivers over two major railroads, three water resources and local roads, and over a major distribution center for UPS and Burlington Northern Santa Fe (BNSF) Railway. The new bridge construction includes two new, side-by-side, bridge structures that will increase capacity from four lanes to five lanes in each direction. Throughout construction of the new bridge, four lanes of traffic will be maintained in each direction as 150,000 vehicles travel on the Mile Long Bridge daily.

BNSF Bridge Over I-294
The Burlington Northern Santa Fe (BNSF) bridge over I-294 is a major project within the Central Tri-State Tollway (I-294) Corridor. The BNSF railway bridge carries the triple-track railroad over I-294 between Hinsdale and Western Springs. Work on this project includes the construction of a bypass bridge that will allow for uninterrupted freight and commuter rail operations during the bridge reconstruction. Upon completion of the bypass bridge, the main bridge will be lengthened and replaced with a wider two-span steel beam structure to accommodate four tracks and allow for reconstruction and widening of the Tollway underneath the bridge.
