WisDOT wants contractor feedback on its plans to use Design-Build to construct the I-90/94 bridges over Mirror Lake near Wisconsin Dells.

The department published its draft Request for Proposals documents to the project webpage this week.

WTBA members can review the project books HERE and submit comments via email to DOTDesignBuildSubmittals@dot.wi.gov.

Comments received during the industry review period will be considered as WisDOT continues development of the final RFP for the I-90/94 Mirror Lake Bridges and USH 12 Interchange Design-Build Project.

Please review the preferred formatting of comments on page 2 of THIS document before sending your email.

The bridge replacement is an early piece of the massive $4.6 billion plan to expand and rebuild 67 miles of I-39/90/94 between Madison and Wisconsin Dells.

A statement of qualifications will be published to the project page on Nov. 19, 2026. WisDOT intends to issue its finalized RFP sometime in late December.
