I-35 Twin Ports Interchange traffic impacts

Duluth, Minn. – Due to recent snow totals, the I-35 traffic impacts scheduled to begin Tuesday, March 14, in Duluth have been delayed. Beginning next week:

  • Southbound lanes will close from just north of Garfield Avenue to just south of 27th Avenue West. This closure will allow for bridge girder installation and decking over the southbound lanes.
  • Traffic will be placed in two-lane, two-way configuration on the northbound side of I-35.
  • Due to the southbound lane closure, the southbound ramp to 27th Avenue West will also close. A ramp detour will route traffic south to 40th Avenue West and then back north to 27th Avenue West.
