Major bridge overhaul to reshape traffic in St. Paul for a year

The Minnesota Department of Transportation (MnDOT) has announced the closure of the John Ireland Boulevard bridge in St. Paul for nearly a year, marking a key stage in the state’s ongoing infrastructure renewal programme.

The 60-year-old bridge, which links the state Capitol and the Cathedral of St. Paul, will be completely disassembled and rebuilt within its current footprint to meet updated weight standards and improve long-term safety. Enhancements will also include upgraded pedestrian and cyclist access as part of MnDOT’s focus on multimodal transport.

The bridge’s closure, timed after the Twin Cities Marathon, will redirect traffic to the Marion Street bridge. The project is part of a larger $16.2 million investment covering nine bridges across I-94 and I-35E, including those at Jackson Street, Robert Street, and Wabasha Street North. These works will involve structural repairs, repainting, and intermittent weekend freeway closures through next year.

While MnDOT confirms the existing structure remains safe, this proactive rebuild aims to future-proof critical routes in downtown St. Paul against modern demands and heavier traffic flows. For businesses and commuters, strategic planning around detours will be essential as the construction progresses toward its August reopening target.
