I-35 Duluth Bridge Rehabilitation

St. Louis County

Traffic Impacts

All I-35/Lake Avenue bridge ramps in Duluth will reopen on Friday, Oct. 4. The Michigan Street onramp to northbound I-35 will also reopen at this time.

The 5th Avenue West to I-35 northbound onramp will close on Friday, Oct. 4 to allow for crossover construction in preparation for 2025 work on the I-35 mainline bridges. Left lane closures on both northbound and southbound I-35 between 5th Avenue West and Lake Avenue will continue for this work. Crossover construction is expected to be complete by late October.

Work in 2025 will reduce I-35 to one lane in each direction and require 5th Avenue West ramp closures.
