The Indiana Department of Transportation has approved Indiana Toll Road Concession Co. plans to rebuild three aging ramp bridges within the footprint of the Lake Station interchange, where the Indiana Toll Road, the Borman Expressway and Ind. 51 converge.
That project calls for upgrading current bridge decks, according to Ryan Olsen, infrastructure program director with Indiana Toll Road Concession Co. This construction will cause traffic to be rerouted at the Borman’s milepost 17, the Gary east interchange, Olsen said.
ITRCC wants to start the project with bidding in 2013 and have most of the work done in 2014, he said. Olsen said he anticipates the work completed by early to mid-2015.
State Toll Road money would fund this project, which doesn’t add any traffic capacity, Olsen said, but allows the bridges to be used through their 100-year lifespan.
The complex dual interchange first opened to traffic in 1965. Construction will remove or replace the bridges' steel beams, railings and crumbling concrete deck. Portions of the existing abutments and vertical piers will be replaced or rehabilitated.
The three bridges being replaced are a bridge on the westbound entry ramp over the Indiana Toll Road, a bridge on the westbound exit ramp over the Indiana Toll Road and a bridge over the Borman Expressway for the road interconnecting to the Indiana Toll Road.
ITRCC operates and collects tolls on the 157-mile Indiana Toll Road under a 75-year lease with the Indiana Finance Authority.
