Project Description: With the goal of reducing congestion and improving safety and mobility along the route, United completed preliminary and final design on 15 bridges for the upgrade and realignment of US 31 from US 30 in Plymouth to the US 20 bypass in South Bend. These projects included multiple bridge types from single-span prestressed girders to a three-span steel plate girder structure with integral post-tensioned straddle bent pier caps at a single-point interchange.
United also completed the “Fast Track” rural five-mile Grading Contract and the more complex urban design in the northern two miles. The six different urban Contracts included pavement reconstruction, retaining walls, local road improvements, bridge replacements, signing, signal design, and a single-point urban interchange.
This project is part of the larger Major Moves initiative to upgrade the route to freeway standards from Indianapolis to South Bend.
