Systemwide Facilities

Challenge: Reconstruction of Plazas 28 and 34 of the Illinois Tollway system while maintaining at least one lane of active traffic open at all times at existing toll plazas for revenue continuity.

Solution: Provide contract documents that meet client expectations regarding the scope, schedule, and budget.

Result: Project is currently in design.

Phase I and II engineering services were required for preparing engineering studies, contract drawings, and specifications related to select vertical facilities throughout the Tollway system. Several Tollway ramp plaza facilities required repair, potential relocation, and replacement. Phase I engineering services were required to perform a functionality assessment at each facility and provide a recommended action plan at each location. Phase II engineering services were required at select locations where Tollway stakeholders deemed the Phase I recommendations acceptable.

Tolls included:
» Toll Plaza 28 Golf Road along I-294 (southbound exit ramp and northbound entrance ramp)
» Toll Plaza 34 75th Street/Willow Springs Road along I-294 (southbound exit ramp)
» Toll Plaza 38 95th Street along I-294 (northbound exit ramp and southbound entrance ramp)
» Toll Plaza 40 159th Street along I-294 (two southbound exit ramps and two northbound entrance ramps)

Milhouse is responsible for Tolls 28 and 34, whose scope involves the demolition of existing plaza canopies and the construction of new overhead all electronic tolling monotubes and continually reinforced concrete pavement. Milhouse is assisting in geometrics, Maintenance of Traffic (MOT), removals, pavement marking, and signing scope in developing the contract documents.
