The existing Taylor Avenue Underpass under the Union Pacific Railroad (UPRR) West Line was a narrow, one-lane passage beneath a busy commuter and freight rail line connecting both pedestrians and drivers to residences, a recreational path, a local high school and more. A jack-and-bore solution to separate pedestrians with a new underpass apart from the vehicular one greatly improved safety, mobility and access, all without interrupting train service. It also significantly improved the safety and ability of emergency vehicles to traverse through the underpass without the use of a spotter.
Benesch led preliminary design, final design and construction management on this project. It is exemplary in its application of engineering principles to design and build a cost-effective alternative in a very short timeframe amidst a number of significant complexities, including:
- Extensive coordination with the UPRR and Metra due to the 150 freight and passenger trains per day
- Utility relocation
- Stakeholder coordination, including residents, Illinois Prairie Path users, Glenbard East High School, etc.
- A careful staging scheme given the tight site constraints
