Challenge: Reconstruction of Plazas 3,4, and 59 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 the client’s expectations for scope, schedule, and budget.
Result: Project is currently in design.
Phase I and II engineering services were required to prepare engineering studies, contract drawings, and specifications for 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 conduct a functional assessment at each facility and provide a recommended action plan for each location. Phase II engineering services were required at select locations where Tollway stakeholders deemed the Phase I recommendations acceptable.
Tolls included:
» Toll Plaza 3 Genoa Road on I-90
» Toll Plaza 4 Illinois Route 173 (West Lane Road) on I-90
» Toll Plaza 59 Farnsworth Avenue on I-88 (eastbound entrance ramp from southbound North Farnsworth Avenue)
Milhouse is responsible for all three plazas, with scopes that involve the demolition of existing plaza canopies and the construction of new overhead all-electronic tolling monotubes and continually reinforced concrete pavement. Milhouse is assisting with geometrics, Maintenance of Traffic (MOT), removals, pavement marking, and signing scope during the development of the contract documents.
Under this bulletin contract, Plaza 67 will also undergo similar enhancements in 2027.
