Low bid of $33.3 million keeps Superior Street rebuild on track

Duluth’s long-planned West Superior Street rebuild cleared a major financial test when bids came in with a low offer of $33.3 million, a price that could keep the project moving toward a May start without the kind of budget shock that can stall public works.

The project covers 1.65 miles of West Superior Street from Carlton Street to West Michigan Street through the Lincoln Park Craft District. City officials have treated it as far more than a paving job. The work is designed as a full reconstruction of the roadway and the aging utilities beneath it, along with traffic signal replacement, stormwater improvements, street lighting replacement, pedestrian upgrades and multimodal changes for cyclists and other lightweight human- and electric-powered devices.

That scale makes the bid especially important for businesses and drivers who depend on the corridor every day. Superior Street carries downtown traffic, deliveries, transit, pedestrians and utility work, so the difference between a manageable bid and an overrun can determine whether the city stays on schedule or faces delays, access problems and added pressure on the capital budget. The lower bid gives city leaders more room to absorb contingency costs and reduces the chance that the project will be pushed back.

The timing also signals that the work is entering a new phase. Earlier city materials said construction was scheduled for 2025 to 2028, and the city said design was nearly complete at its fifth public meeting on Nov. 13, 2024. The latest bid result suggests the project is now moving from planning into the construction-award stage, with work potentially beginning in May.

Funding for the rebuild has been assembled from several sources, including a $24,990,160 federal Rebuilding American Infrastructure with Sustainability and Equity grant administered by MnDOT and a $7,684,530 matching grant tied to the Infrastructure Investment and Jobs Act. City documents also pointed to Municipal State Aid for Streets and utility funds, underscoring the size and complexity of the job.

Some of the groundwork is already visible. The city began tree removal along West Superior Street between Piedmont Avenue and 18th Avenue West on March 31 and said more than 300 trees would be planted as part of the full project, with 50% more trees replanted afterward. Officials also warned that lane shifts and parking restrictions would come with that clearing work, a preview of the longer disruption likely to hit the corridor once major construction begins.

The rebuild is being framed as a rare chance to replace infrastructure that has been in place for generations. Earlier reporting noted that some utilities under West Superior Street date back to the 1860s. For city leaders, the $33.3 million bid is a sign the work can still be delivered. For businesses and drivers along one of Duluth’s most important streets, the real test will be whether the city can keep the project moving while holding down cost and access problems through the years ahead.
