The Michigan Department of Transportation (MDOT) is replacing two 100-year-old railroad bridges over Jackson and Mechanic streets in the city of Jackson. These railroad bridges are on a segment of railroad owned by MDOT within the federally designated high-speed rail corridor between Chicago and Detroit/Pontiac, which supports Amtrak passenger service and Norfolk Southern freight trains. The project not only enhances this regionally significant rail corridor, but it also carries local significance as a key component to revitalizing downtown Jackson by improving safety and mobility for motorists and pedestrians.

Work began in March 2020, starting with advanced utility relocation in the project area and is expected to last through December 2021. Actual rebuilding on the Jackson and Mechanic railroad bridges is expected to begin in March 2022 and is planned to be substantially complete in November 2022. The project also includes rebuilding the Blackstone Road grade crossing and approaches, replacing approximately 1,300 feet of railroad corridor retaining walls, rebuilding and lifting approximately 4,000 feet of railroad track, and adding a nonmotorized pathway under the Mechanic Street railroad bridge. The two bridges will be replaced using accelerated bridge construction techniques.

How Much Roadway Clearance Will There be With the New Bridges?

The Jackson Street bridge will be raised to provide approximately 14 feet, 6 inches of clearance. For Mechanic Street, the proposed clearance will be 10 feet, 7 inches. Physical constraints, such as the M-50 (Louis Glick Highway) intersection, the Jackson and Lansing Railroad grade crossing, the Grand River water table, the nearby railroad bridge over the Grand River, and the Francis Street grade crossing, all limit the ability to greatly improve the proposed clearance at Mechanic Street.

Safety Benefit:

There will be detours on local streets and periodic lane closures on M-50 (Louis Glick Highway) to accommodate work. Intermittent full closures are expected on Jackson and Mechanic streets at the railroad bridges through November 2022. Railroad traffic will be halted for one week when the new bridges are installed.
