Traffic impacts
Current
- March 24 to 26 - Southbound I-35 will be routed into a single lane onto Lower Michigan Street between Garfield Avenue and 27th Avenue West.
- March 24 to 26 - Northbound I-35 will close completely between 40th Avenue West and Garfield Avenue. All northbound traffic will be routed off I-35 at 40th Avenue West. The signed detour will follow Highway 2 (Bong Bridge) to Superior, Wisconsin then onto Highway 535 (Blatnik Bridge) and back into Duluth.
- Traffic to and from Port Terminal Drive, is being detoured onto Helberg Drive through the 2023 construction season.
- All ramps to Hwy 53 and I-535 are closed.
Detours are in place. To avoid heavy traffic anticipated on Garfield Avenue, we strongly encourage use of the Bong Bridge.
