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
• Drainage improvements
