Traffic impacts

Current

Learn more about this project, including project stages and how to do the zipper merge when travelling through this project area. All traffic impacts are tentative and weather dependent.

Lane closures

Through mid-December

• Periodic lane closures on I-35 in both directions between Hwy 8 and the I-35W/I-35E split
• Periodic lane closures on I-35W/I-35E between I-35 and one mile south of the split

Upcoming

Details on upcoming traffic impacts will be provided as they become available.

About this project

Six miles of I-35 from just south of the I-35 split to a half mile north of Hwy 8 at the Chisago/Washington county line will be resurfaced. Road resurfacing helps to preserve and extend the use of the pavement. The work will also include replacing three bridges.

Summary of work

• Resurface existing pavement
• Replace the Hwy 97 bridge over I-35 with a diverging diamond interchange for better traffic flow and improved safety
• Update crosswalks at Hwy 97 to meet modern accessibility standards
• Replace the flyover ramp from WB Hwy 8 to SB I-35 with a loop ramp
• Replace the WB Hwy 8 bridge over I-35
• Replace the NB I-35W bridge over SB I-35E
• Drainage improvements

Do the Zipper Merge

When you encounter a construction zone where a lane will be closed, perform the zipper merge. A zipper merge occurs when motorists use both lanes of traffic until reaching the defined merge area, and then alternate in a "zipper" fashion into the open lane.
