Bridging the Gap: Highlighting Minnesota’s Need for Bridge Construction

The Minnesota Department of Transportation reports that the state boasts more than 20,000 bridges.  Among these, a significant portion are identified as requiring repairs. Data from the American Road & Transportation Builders Association (ARTBA) indicates that nearly 600 bridges are classified as structurally deficient. Efforts by the state and other government entities to address these issues are underway, but various factors must be taken into consideration before initiating bridge projects.

Securing funding remains a significant challenge in the efforts to revamp infrastructure. In 2023, MnDOT dedicated nearly $1.3 billion to various construction projects. Additionally, in January of the same year, the Minnesota House granted approval for the expenditure of approximately $315 million from the federal Infrastructure Investment and Jobs Act. Despite these substantial commitments, achieving significant enhancements in the overall condition of bridges will be a gradual process. Only a fraction of the funds will be directed towards bridge construction, and the impact of Minnesota’s climate and associated use of deicing salts continues to contribute to the deterioration of existing structures.  According to the Minnesota Infrastructure Reports from ASCE, ( the state will require $8.2 billion in funding over the next two decades to address identified rehabilitation and repair needs. However, the current budget only allocates $4 billion, resulting in a substantial $4.2 billion shortfall.

The success of bridge and road construction projects hinges significantly on public perception. Owners make efforts to ease inconveniences for the public, although these measures may contribute to increased costs and a slowdown in construction progress. Construction projects are meticulously planned and phased to minimize disruptions for the traveling public and mitigate any negative impacts on local businesses. It is crucial not to overlook pedestrians in the vicinity, especially those near schools, residential areas, parks, and popular walking or biking spots, during construction projects.

A notable upcoming endeavor involves the Blatnik Bridge ( in Duluth, MN, ranking as the second-longest bridge in Minnesota. Crossing the backwater of Lake Superior, this bridge plays a crucial role in facilitating commuting between Duluth, MN, and Superior, WI, in both directions. Although specific details are pending disclosure, construction is set to commence in 2027, with an estimated cost of over $1 billion and a projected construction timeline of five years. This venture is poised to become one of the most financially significant public projects in the state’s history. Given its substantial cost and extended duration, the project will demand a considerable financial commitment that might otherwise be allocated to various construction projects across the state.

Minnesota has advanced in its strategy for infrastructure asset management. Sustained investment, effective management, and thoughtful planning are essential elements to ensure the safety, usability, and longevity of the state’s bridges for years to come.
