Jane Addams Memorial Tollway (I-90) Widening and Reconstruction                     Design Upon Request

Project Description

In 2011, the Illinois Tollway Board of Directors approved the 15-year, $12 billion capital program, Move Illinois: The Illinois Tollway Driving the Future. Move Illinois committed $2.2 billion to rebuilding and widening of the Jane Addams Memorial Tollway (I-90).

The proposed improvements will improve safety with wider shoulder lanes and auxiliary lanes, increase capacity by an estimated 30,000 more vehicles per day, reduce congestion and thus improve travel times from Elgin to the Kennedy Expressway by nearly a half hour on average. The design required the addition of a fourth travel lane in each direction and either the rehabilitation or full reconstruction of various crossroad bridges and interchanges located within the project limits.

The particular project is a Design Upon Request for Phase II Engineering services involving several task order projects, among them are several cross road bridge design and reconstructions throughout the west half of the corridor, park and ride parking lot construction, and on call, as needed work related to the Jane Addams Tollway corridor.

d’Escoto, Inc.’s Role

d’Escoto, Inc. has provided Phase II Civil Design Services for the cross road bridge reconstruction projects over I-90. These bridges include the US Route 20 dual bridges and the Anthony Road, Garden Prairie Road, and Spring Center Road bridges over I-90.

Additionally, d’Escoto, Inc. staff performed the following:

Prepared the Maintenance of Traffic plan for I-90 and along the side roads
Involved in creating the alignment and ties, barrier warrants, typical sections, detour plan, removal and proposed plan, roadway profiles, super elevation correction plan, erosion and sediment control, final landscaping, pavement marking, and the cross sections
Prepared Concept Drainage Reports for each bridge consisting of drainage design criteria, proposed drainage conditions, stormwater detention analysis, base floodplain map, and accompanying exhibits. Created contract plans consisting of structure and pipe sizing, velocity analysis, and impact of outlets
Created the contract special provisions and estimate of cost

d’Escoto, Inc.’s Role

d’Escoto, Inc. has provided the following Phase II Civil Design Services for I-90 from the Elgin Toll Plaza to the Kennedy Expressway (I-294):

Prepared the IL-31 & IL-25 Interchange Design Concept Reports and cost estimates with various design and design impact alternatives.
Prepared the earthwork quantities, retaining wall layouts and right of way impacts for the Master Plan.
Provided structural design engineering support by designing multiple moment slab section scenarios in coordination with over 20,000 feet of a structural wall system.
Determined structural limits based on ROW constraints, drainage considerations, and the future implementation of Intelligent Transportation System structures. The design required the detailing of reinforcement needs within the moment slab and the calculation the load transfers associated with an MSE retaining wall.
Designed structural support for noise abatement walls to be mounted onto the MSE wall and the associated safety barrier. Work on the segment of I-90 from Chicago to Elgin is scheduled to be complete in 2015.
