Major Bridge Closures Shift Traffic Plans in St. Joseph, Mishawaka

Two major bridge construction projects are impacting traffic in St. Joseph, Michigan, and Mishawaka, Indiana. The Bicentennial Bridge between St. Joseph and Benton Harbor is closed all weekend due to mechanical issues, with the closure expected through at least Tuesday; officials have adjusted traffic plans by opening the M-63 Whitwam Drive entrance ramp as an alternate route to mitigate congestion, especially during St. Joseph's fireworks event. In Mishawaka, the Main Street Bridge over the Toll Road has completed work on the northbound lanes and has now closed the southbound lanes for repairs, with an expected closure duration of two to three months. Motorists heading south are advised to use detours via Fir Road, University Drive, and Douglas Road, with electronic message boards in place to warn drivers of the disruptions. Both projects have significant traffic implications and authorities are actively managing alternate routes to ease commuter challenges during these extended closures.
