NO. 1 BRIDGE: CLINE AVENUE BRIDGE

BRIDGE OVER INDIANA HARBOR IN EAST CHICAGO NAMED #1 BRIDGE OF THE YEAR

The new Cline Avenue Bridge is an elevated expressway in Northwest Indiana that connects State Highway 912 to I-90, crossing over the Indiana Harbor and Ship Canal in East Chicago, Indiana.

The new bridge is on an existing alignment and replaces a structurally deficient bridge that was closed in November 2009 and then demolished by the Indiana Department of Transportation.

Construction of the new replacement bridge started in July 2017. The new bridge is 6,236 ft long with a 316-ft main span over the Indiana Harbor and Ship Canal, providing 100 ft of vertical and 200 ft of horizontal navigational clearance.

The superstructure is composed of sustainable, post-tensioned concrete, single cell box girders designed with low maintenance features for over a 150-year life. The overall project is 9,850 ft long, which includes connecting the new concrete segmental bridge with a 2,400-ft-long adjacent existing steel beam bridge. Rehabilitation of the existing steel beam bridge occurred concurrently with construction of the new concrete box girder Cline Avenue Bridge.
