Milhouse is supporting the reconstruction of select Illinois Tollway ramp plaza facilities as the system continues modernizing its tolling infrastructure for safer, more efficient all-electronic operations.
This project includes work at Toll Plaza 28 at Golf Road along I-294, Toll Plaza 34 at 75th Street/Willow Springs Road along I-294, Toll Plaza 38 at 95th Street along I-294, and Toll Plaza 40 at 159th Street along I-294. Milhouse is responsible for Toll Plazas 28 and 34.
A key challenge of the project is reconstructing the existing toll plaza facilities while maintaining active traffic through the work zones. At least one lane of traffic must remain open at all times to support driver mobility and revenue continuity for the Tollway.
Milhouse is providing Phase I and Phase II engineering services, including engineering studies, contract drawings, and specifications for the selected vertical facilities. Phase I services include functionality assessments at each facility and the development of recommended action plans. Phase II services advance accepted recommendations into contract documents that align with the Tollway’s scope, schedule, and budget expectations.
For Toll Plazas 28 and 34, Milhouse’s scope includes demolition of existing plaza canopies and construction of new overhead all-electronic tolling monotubes, along with continuously reinforced concrete pavement. Milhouse is also supporting geometrics, Maintenance of Traffic, removals, pavement marking, and signing as part of the contract document development.
The project is currently in design.
