During a news conference at the River Raisin Bridge in Monroe, Michigan, on December 9, U.S. Transportation Secretary Pete Buttigieg released a new report detailing 18 of the most economically significant bridges that are being rebuilt or repaired with funding from the Biden-Harris Administration. 

In November of 2021, in anticipation of the passage of the bipartisan Infrastructure Law, President Biden announced that funding from this historic legislation would fix up to 10 of the most economically significant bridges in the nation. In addition, the funds would be used to improve safety and efficiency, strengthen supply chains and support America’s economic competitiveness, and restore critical connections that are vital to commuters, emergency responders, truck drivers, and public transit riders. 

Infrastructure Investments in Action

Three years later, the Biden-Harris Administration has surpassed that goal, Buttigieg said, funding more than 11,400 bridge projects across the country. These include 18 of the nation’s most economically significant bridges. 

Each of these 18 bridges was awarded a U.S. Department of Transportation grant of $100 million or more, has a total estimated project cost of greater than $250 million, and is vital to American supply chains and the economy. 

Collectively, these 18 bridges are crossed by more than 1.2 million vehicles a day and an estimated 57.2 million trucks annually.

Federal funding for these projects comes from the Bipartisan Infrastructure Law’s Bridge Investment Program and the Bridge Formula Program. Altogether, these investments represent the largest dedicated investments in the nation’s bridges since the Eisenhower era – as well as the Infrastructure for Rebuilding America (INFRA) Grant Program, and the National Infrastructure Project Assistance (Mega) Program. 

“For commuters, for truck drivers, for anyone who uses America’s interstate highways, our bridges are essential to keep people and goods moving—and the Biden-Harris Administration has taken unprecedented steps to repair and rebuild these critical structures,” Buttigieg said. “We’ve made good on our promise to address our country’s most economically significant bridges—and are now going beyond our initial goal of ten bridge megaprojects—while also delivering much-needed repairs to thousands of other bridges nationwide to make driving safer and supply chains stronger." 

Secretary Buttigieg was joined by Mayor Robert Clark of Monroe, Michigan, and leaders from the Michigan Department of Transportation (MDOT) to make this announcement at the River Raisin Bridge, one of the 18 bridges included in the report.

Replacing the River Raisin Bridge

On October 21, 2024, USDOT announced $196 million in INFRA funding to replace the deteriorating River Raisin Bridge along I-75. The new structure will feature a new crossing to accommodate estimated future traffic, update and replace six existing structures. It will include two bridges over Class I railroad lines – with new ones designed for a 100-year lifespan. The project will also reconstruct over two miles of roadway to improve safety and the efficiency of freight movement along this vital U.S.-Canada trade corridor.

The River Raisin Bridge serves as a vital connection point between Detroit and Toledo. It currently serves approximately 61,000 vehicles daily, with 25% being truck traffic. 

I-75 is also an important component of the wider transportation landscape in Southeastern Michigan, which includes railroads and the Port of Monroe. If the bridge were not replaced and closed, it would lead to a loss of approximately $58 million in Gross Regional Product and $129 million in loss of Michigan business output/sales.
