The existing truss bridge had been closed to traffic since 2006 due to structural deficiencies that deemed the bridge unsafe for public use. This project, run in tandem with the Division Street Bridge Rehabilitation Project, connected the two halves of Blue Island with a beautiful pedestrian bridge that will be part of the Cal-Sag Greenway Trail.
The work included the complete demolition of the existing concrete deck followed by the removal and replacement of the existing structural steel displaying significant section loss. The project included 82,570 pounds of new stringers, diaphragms, and bottom lateral bracing that support the 17 foot wide pedestrian path with 200 cubic yards of high performance concrete superstructure.
Also included in the project was the containment and removal of the existing lead paint followed by a fresh application of paint, three precast concrete pier caps, abutment backwall concrete removal and replacement, and the relocation of existing watermain and ComEd electrical services.
