I-35 Duluth Bridge Rehabilitation

St. Louis County

Traffic Impacts

The following ramps to and from I-35 remain closed:  

  • I-35 northbound off-ramp to Lake Avenue bridge
  • I-35 southbound off-ramp to Lake Avenue bridge
  • I-35 southbound on-ramp from Lake Avenue bridge
  • I-35 northbound on-ramp from Lake Avenue bridge
  • I-35 northbound on-ramp from Michigan Street

Lanes will continue to be closed on I-35 northbound and southbound between 5th Avenue West and 13th Avenue East (north termini of tunnels). Ramps are expected to reopen by October 11 and will open sooner if possible. Detour signage is posted. The extent of work needed was greater than originally planned for and is taking longer than expected.

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