The Twin Ports Interchange Project in Duluth, Minnesota, began in 2020 with prep work and the reconstruction of the 27th Avenue West bridge over I-35.

The goal of the $435 million project was to improve safety and freight mobility by redesigning the confusing and aging "can of worms" section of I-35. This included:

  • Providing a new conventional design
  • Relocating all exits and entrances to the right side of the roadway, eliminating all left exits
  • Improving merging sight distance and eliminating merge conflicts
  • Eliminating weaving problems near the interchange
  • Providing lane continuity for through I-35 traffic

Since the project began, motorists throughout the area have encountered slowed traffic, countless ramp and road closures, and detours.

Now, at long last, all the hard work from DNR crews and the inconveniences experienced by motorists traveling through northern Minnesota are about to pay off.

Twin Ports Interchange Ribbon Cutting Ceremony Announced

The Minnesota Department of Transportation has announced plans for its ceremonial ribbon-cutting event for the Twin Ports Interchange project. The event is set for Monday, October 6, at 1:00 p.m. underneath the newly built Highway 53 bridge located at 20th Avenue West and 1st Street in Duluth.

It will officially mark the completion of the Twin Ports Interchange project and will include remarks from state and local leaders, followed by a walk up the exit ramp to the bridge deck for an official ribbon cutting. Refreshments will also be provided.

In the days following the event, ramp connections between Highway 53/I-35/I-535 will open for the first time since 2021. Then, next summer, landscaping and clean-up efforts will continue in the area.
