Construction itself may not start until 2028, but plenty of work is going on right now to get ready for the massive 67-mile reconstruction of I-39/90/94.

WisDOT will hold a virtual public information meeting next month to give people an update on the planned schedule and ask project team members questions.

The meeting is set for Tuesday, Nov. 10 at 5:30 p.m. You can join the meeting HERE.

The overall project runs through the heart of Wisconsin where three interstates combine between Madison and Wisconsin Dells.

There are 113 bridges, 15 existing interchanges and two potential new ones all in the cue for improvements along with expanding the freeway.

The work could take more than a decade and cost at least $4.6 billion according to WisDOT’s latest estimates.

The department plans to use Design-Build early in the process to replace the Mirror Lake Bridges.  That tool could save taxpayers about $300 million, according to WisDOT Secretary Kristina Boardman.

Statements of Qualification for the bridges are due Nov. 19 and WisDOT intends to issue a Request for Proposals in late-December.
