The Minnesota Department of Transportation (MnDOT) is seeking engineering services to conduct a Vessel Collision Study for the Wabasha Bridge, which spans the Mississippi River between Minnesota and Wisconsin. The study will assess vessel impact risks, develop protection alternatives, and provide preliminary cost estimates. Bidders must be pre-qualified consultants and submit letters of interest.
MnDOT requests letters of interest for engineering services to develop a Vessel Collision Study Report for the Wabasha Bridge (MN Bridge 79000, WI Bridge B-6-79). The bridge carries Minnesota Trunk Highway 60 over the Mississippi River between the cities of Wabasha, Minnesota, and Nelson, Wisconsin. The existing bridge was built in 1987 and was designed prior to the AASHTO Guide Specifications and commentary for Vessel Collision Design of Highway Bridges (1991), and subsequent updates included in the current LRFD Bridge Design Specifications. Work includes completing a certified Vessel Collision Study Report for the Wabasha Bridge to assist the states in risk assessment. This project also includes scoping, concept design/sketches of pier protection, and preliminary construction cost estimates for vessel collision protection, as anticipated in the certified Vessel Collision Study Report. Presentation of findings to MnDOT, WisDOT, the United States Coast Guard (USCG), the United States Army Corps of Engineers (USACE), the Federal Highway Administration (FHWA), and other agencies may also be required. Open to pre-qualified consultants only (letters of interest).

Minnesota DOT in Minnesota is using this solicitation to procure bridge work. Public agencies typically advertise this kind of work as a Request for Proposals (RFP), evaluating bidders on a combination of qualifications, technical approach, and price. Bidders responding to a bridge solicitation in Minnesota are generally expected to provide proof of liability insurance and workers' compensation coverage, hold any state license or trade certification required for the scope of work, and post performance and payment bonds for contracts above the agency's threshold.
Federal-aid funding flowing through programs such as the Federal Highway Administration, FEMA, or the Infrastructure Investment and Jobs Act brings additional compliance requirements on solicitations like this one, including Davis-Bacon prevailing wage, Buy America provisions where applicable, and Disadvantaged Business Enterprise (DBE) participation goals set by the issuing agency. PublicBidSearch indexes this solicitation alongside other open bids in Minnesota so contractors and vendors can compare active opportunities by category, agency, or location without monitoring each procurement portal individually.
To submit a proposal for this RFP, review the full solicitation documents for Minnesota DOT's exact scope of work, submission format, and any mandatory pre-bid meeting or site visit. Responses must be received before the July 17, 2026 deadline — public agencies routinely reject late submissions regardless of cause. Confirm how the agency accepts responses — through an electronic procurement portal, as a sealed hard-copy bid, or by email — because the required method varies by agency and a non-conforming submission can be disqualified. Vendors that have not previously contracted with Minnesota DOT should confirm whether registration on the agency's vendor system is required to be eligible for award.
