Michigan enacted major infrastructure financing to repair 42 structurally deficient road and freight rail bridges in Wayne, Oakland, and Macomb counties.
DETROIT, MI — Michigan Governor Gretchen Whitmer signed bipartisan infrastructure legislation on Sunday afternoon in Detroit, authorizing $320 million in dedicated capital bonding to repair and replace 42 critical road, highway, and rail overpass bridges across Southeast Michigan.
The funding, approved under the Building Michigan Bridges Program through the Michigan Department of Transportation (MDOT), targets high-traffic structures that have exceeded their original 50-year design life. Priority civil engineering projects include the replacement of the I-94 overpass bridges in Wayne County, critical commercial rail grade separations in Oakland County, and deck replacements along M-59 in Macomb County.
The reconstruction specifications mandate corrosion-resistant stainless-steel reinforcing rebar and ultra-high-performance concrete (UHPC) overlays designed to extend bridge operational lifespans to 75 years.
"We are fixing the damn bridges to keep Michigan motorists safe, eliminate dangerous detours, and support our automotive supply chains," Whitmer said during a bill-signing event near the Detroit riverfront.
Regional logistics operators and commercial trucking associations commended the targeted bridge rehabilitation, noting that structural weight restrictions on aging county overpasses currently force commercial trucks onto lengthy residential detours, adding over $40 million in annual fuel and delay overhead.
Local municipal leaders praised the state funding for covering 100% of engineering and construction costs without requiring local property tax matches.
MDOT will tender the first phase of bridge engineering contracts in October 2026, with construction breaking ground in spring 2027.
The City of Los Angeles approved capital contracts to install ductile iron seismic water trunk lines across Van Nuys and North Hollywood to prevent pipe ruptures during earthquakes.

Dallas authorized civil engineering construction for a 280-acre stormwater detention basin along the Trinity River floodplain to prevent residential flood inundation.

The Federal Highway Administration awarded grants to construct six multi-megawatt commercial charging plazas capable of recharging electric freight trucks in under 45 minutes.
