New Ramp Closures Coming At Twin Ports Interchange In Duluth
It was a big week for the Twin Ports Interchange Project in Duluth. On Tuesday, August 21, the Minnesota Department of Transportation opened the rebuilt I-35 and I-535 bypass connections through the Twin Ports Interchange project.
Before opening the connections, MnDOT had advised motorists that a one-lane bypass had been temporarily constructed at the I-535/Garfield Avenue interchange to facilitate reopening the I-535 connection between Wisconsin and Minnesota.
Now that the reopening has successfully been completed, MnDOT announced new closures near Garfield Avenue that will be in place for just under two months.

The $435 million Twin Ports Interchange Project looks to improve safety by:
- Providing a new conventional design
- Relocating all exits and entrances to the right side of the roadway
- Improving merging sight distance and eliminating merge conflicts
- Eliminating weaving problems near the interchange
- Providing lane continuity for through I-35 traffic
Construction is expected to be completed around the summer of 2026 when landscaping and clean-up are expected to begin.
