The state is giving builders until Monday, Nov. 30, to submit bids for an emergency repair project for three failing bridges on the Zoo Interchange.
The Wisconsin Department of Transportation sent out a request for proposals for an emergency contract on Thursday. The aging bridges pass above other segments of the highway, and if they are not replaced soon there is a risk that concrete will start falling off the bridges onto the traffic below.
After analyzing proposals to patch up or reinforce the existing bridges, the department opted instead to completely replace the three structures. The department estimates it will take 16 weeks per bridge for the construction work.
The state will select contractors based on cost, project schedule, ability to minimize traffic closures and the composition of the project labor force.
