Interchange at Eola between Diehl and Bilter Road at I-88

CLIENT: Illinois Tollway

DESCRIPTION: 

OMEGA provided construction engineering services for the Illinois State Toll Highway Authority. The project scope included the construction of a new interchange on the Reagan Memorial Tollway (I-88) at Eola Road with a construction cost of $25 million. The project was built on an accelerated schedule with construction starting in April 2009 and was completed by November 2009.

The project consisted of the construction of a full interchange west of Eola Road on the Reagan Memorial Tollway. The west bound ramps provided access to and from Eola Road via Bilter Road. The east bound ramps provided access to and from Eola Road via Diehl Road. Three signalized intersections were included in the improvements. The construction also included: construction of four PCC pavement interchange ramps and appurtenant facilities, unmanned, I-PASS only toll plazas on both the west bound off ramp and east bound on ramp, and roadway lighting along the mainline median and along the proposed ramps.
