Inland Steel Overpass Bridge Removal and Roundabout Construction

Primera provided Stage I, II and III engineering services for the removal of the Inland Steel Overpass bridge over Aldis Avenue, and the construction of a roundabout intersection in East Chicago, Indiana. The existing three-span concrete bridge carried six lanes of traffic.

Primera performed the following services: preparation of a Bridge Condition & Assessment report, preparation of a geometric study which included an analysis of the roadway and bridge vertical and horizontal alignments, development and analyzation of alternative roundabout designs, development of a Project Development Report, development of a set of contract documents and lastly, preparation of the final contract documents.

Roadway improvements included full bridge removal with earth backfill underneath, approximately 2,600-feet of roadway reconstruction northeast of the bridge, and construction of a new roundabout intersection. The roadway drainage system within the area of roadway reconstruction was replaced with a new system tying into an existing structure within the limits of the project.
