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

• Resurface I-35W just south of the split
• Construct the new Hwy 8 ramp/bridge over I-35
• Resurface I-35E just south of the split
• Construct the south half of new Hwy 97 bridge over I-35 and reconstruct all ramps at the interchange

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.
