About this project

MnDOT in partnership with Dakota County, Hennepin County, City of Bloomington and the City of Burnsville are developing a project to replace the bridge and pavement on I-35W between Cliff Rd. and 106th St. Raise I-35W out of the floodplain and improve pedestrian access across the river.

Bridge Demolition Process

Now that traffic is switched to the new northbound bridge, the contractor will safely tear down the former I-35W river crossing while constructing the new southbound bridge in its place. Crews will remove the portion of the bridge over land with conventional breakers (e.g. large jackhammer attachments on excavators). The portion of the bridge over water/wetland will be cut up and removed piece by piece, and the beams will be removed using cranes. The whole process will take 3 months. Please contact the project team if you have any questions or concerns regarding the bridge demolition process.
