Anticipated traffic impacts

Throughout the project MnDOT, is planning to maintain two to three lanes of traffic in each direction on I-35W, with a limited number of weekend closures. 

MnDOT will be closing the southbound I-35W entrance ramp at W 106th Street in early October, and this ramp is expected to remain closed for most of the project.  The northbound exit ramp at W 106th Street will also be closed during some portions of the construction.

Throughout the project, there will be construction traffic accessing the job trailer and work area on the north side of the river via I-35W to W 106th Street to Lyndale Avenue.  While precautions will be taken to minimize the impacts of this traffic, please proceed with care when accessing businesses, neighborhoods, the boat landing and the trailheads in this area.

How is the project funded?

This is a MnDOT project with an estimated construction cost of $127 million.

What is the project's schedule?

The construction began on August 20, 2018 and is expected to be completed in late 2021.

Project history

MnDOT worked in partnership with Dakota County, Hennepin County, the City of Bloomington and the City of Burnsville to develop a design-build project to replace the bridge and pavement on I-35W between Cliff Road and 106th Street.  This process included public open houses in 2015, meetings with affected properties regarding sound walls in 2016, Municipal Consent hearings in 2017 and Environmental document public hearing in 2018.  For more information, please visit the MnDOT design-build website.

The City of Bloomington will be completing a local, City project on W 106th Street towards the end of the MnDOT project.  This project will include reconstruction of W 106th Street between Verdi Road and Lyndale Avenue with pedestrian improvements on this segment and permanent closure of the 106th Street accesses for West Bloomington Freeway and River Terrace.  For more information, please visit the project website
