Current status as of April 2022:
The third and final year of construction recently started on the section from Wolf Road to the O’Hare Oasis. In addition to providing a fifth travel in each direction, the work also includes the rehabilitation of the dual (over one-half mile long) mainline bridges over the Bensenville Rail Yard and the implementation of SmartRoad technology.
-
Phase II design engineering services were performed for the widening and rehabilitation of nearly two miles of the Central Tri-State Tollway (I-294) from the new I-490 Tollway Interchange to the O’Hare Oasis. This contract is part of the Illinois Tollway’s $4 billion improvement of the Central Tri-State from 95th Street to Balmoral Avenue.
-
The proposed improvements included the addition of a fifth travel lane in each direction, reconstruction of the median to accommodate flex lanes, the rehabilitation of the two 28-span, half-mile long bridges over the Bensenville Rail Yard, rehabilitation of the Wolf Road bridge over I-294 and the reconstruction of the O’Hare Oasis ramps.
-
The proposed improvements include the installation of retaining walls and noise abatement walls, drainage improvements, the implementation of Intelligent Transportation System infrastructure, new roadway lighting, regulatory floodway/floodplain impacts and the relocation/protection of existing utilities.
-
Under newly developed Illinois Tollway guidance for soil waste screening, V3 completed the special waste screening which included collecting soil samples as well as development of a soil management memo characterizing soils for disposal. In addition to the soil management memo, V3 evaluated potential environmental concerns with possible acquisition of right-of-way from an adjoining landfill property.
-
A detailed traffic staging plan was prepared to depict the maintenance of four lanes of mainline traffic in each direction along with the maintenance of ramp movements throughout the duration of construction. The project will be phased over a three-year period from 2020 to 2022 and will accommodate the staging of the new I-490 Tollway Interchange to the south.
