Overview
Updated 5 hours agoUS-31 in Whitehall is getting a $2.8 million bridge repair. Construction begins Sept. 8 and is expected to wrap up by mid-November. Drivers face lane closures on the highway, a closed Walsh Road underpass, and a restricted Colby Street exit.
The work targets the northbound and southbound bridges carrying US-31 over Walsh Road and Colby Street. MDOT says the investment will directly and indirectly support 24 jobs. During construction, northbound Exit 128 to Colby Street closes and left turns from southbound US-31 onto Colby Street are prohibited.
Why it matters
Commuters through Whitehall lose a lane on US-31 for two months while MDOT repairs bridges that carry the highway over two local roads.

Historical Context
2 moments from history that rhyme with this story — and how they unfolded.
I-35W bridge collapse (2007)
The eight-lane I-35W bridge over the Mississippi River in Minneapolis collapsed during evening rush hour, killing 13 and injuring 145. The National Transportation Safety Board found a design flaw in the steel gusset plates, compounded by heavy construction loads.
Federal scrutiny of bridge inspection practices intensified, and Congress moved to increase highway and bridge funding.
States strengthened bridge inspection programs and accelerated replacement of structurally deficient spans.
Routine bridge repair projects like Whitehall's are part of the ongoing maintenance that keeps aging spans from reaching a crisis point. The 2007 collapse is the worst-case reminder of why this work happens.
Manistee County US-31 reconstruction (2027-2028)
MDOT plans a $39.5M reconstruction of US-31 from Stronach Road to M-55 in Manistee County, converting 4.8 miles from four lanes to three lanes with a center turn lane. Work begins spring 2027 and runs through fall 2028.
Traffic shifts to one-way operation with a commercial detour around Manistee Lake during construction.
The corridor gets a safer, calmer road profile, part of MDOT's broader US-31 improvements along the Lake Michigan shoreline.
The Whitehall bridge job is the same corridor and the same agency. It shows MDOT investing in US-31 at multiple points up and down the lakeshore in the same period.
