Jackson and Mechanic Streets railroad bridge replacements project in Jackson - Update #2

LANSING, Mich. - The Michigan Department of Transportation (MDOT) closed Jackson, Mechanic, Van Buren, and Detroit streets in Jackson on March 7 to allow crews to safely replace century-old railroad bridges over Jackson and Mechanic streets. The project also includes replacing the railroad grade crossing at Blackstone Street.

The contractor has completed installation of underground utilities, including sanitary, water main, and storm sewer at Jackson Street. The drilling crews have continued installing micropiles at the Jackson Street bridge abutments and have completed a majority of the micropiles at the east abutment. Concrete footings with reinforcing steel bar are being built on the micropiles that will support the bridge. Retaining wall construction is continuing and all steel sheet piling has been driven into the ground on the northwest quadrant of the Jackson Street bridge and the northwest and northeast quadrants of the Mechanic Street bridge. Ground anchor installation has been completed on the northeast and northwest steel sheet pile retaining walls at the Mechanic Street bridge. Drill crews continue to install ground anchors on the remaining steel sheet pile retaining walls at Jackson Street.  

Work will continue with micropiles at both bridge abutments, ground anchors on the remaining steel sheet pile wall at Jackson Street, and building concrete abutments that are supported by the installed micropiles. 

The project is experiencing some delays due to utility conflicts with micropiles, and some bridge work will likely take place in 2023. 

Traffic restrictions:
Local streets will be closed to traffic. Motorists should follow the posted detours. 

Safety benefit:
Replacing these bridges will ensure smooth and safe railroad operations, maintaining this vital part of the state's economy. Closing streets during this type of work is necessary to provide the safest work area possible for work crews and motorists.
