I-35 Duluth Bridge Rehabilitation

St. Louis County

Traffic Impacts

Bridge repair work on I-35 in Duluth is underway. This construction project will resurface the bridge deck and replace joints on I-35 between Mesaba Avenue and 5th Avenue West and work on the I-35 northbound off-ramp to 5th Avenue West and the southbound on-ramp from 5th Avenue West.

Traffic is in to a head-to-head pattern on the southbound lanes. The following ramps are closed as a part of this project: I-35 northbound off-ramp to 5th Avenue West, I-35 northbound on-ramp from 5th Avenue West, I-35 southbound on-ramp from 5th Avenue West, and I-35 southbound on-ramp from Lake Avenue. Access to Hwy 194/Mesaba Avenue from I-35 northbound and access to I-35 southbound from Hwy 194/Mesaba Avenue will be maintained. Detour signage is in place for each closure.

Additionally, access to northbound I-35 is closed from northbound I-535/Blatnik Bridge. The posted detour is I-35 southbound to 27th Avenue West to I-35 northbound. Access from northbound I-535/Blatnik Bridge to Hwy 194/Mesaba Ave is open.

Head-to-head traffic will be in place through mid-August with traffic being switched from the southbound lanes to the northbound lanes in June.
