DULUTH, Minn. -

Starting the week of September 5, the utility upgrades taking place along West Michigan Street in downtown Duluth, will start its fourth phase.

The work will impact vehicle access from Republic Bank to the 5th Avenue West corner for 4-5 weeks. The entry into the 4th Ave West parking ramp is only accessible from 4th Ave., the ramp will be reconfigured to allow temporary exiting at the 4th Ave West and Michigan Street intersection.

Phase 5: concrete repairs along Michigan Street between 6th Ave West and 5th Ave West are also planned for October as a follow up to Minnesota Power's electrical upgrade work last summer.

The north side of Michigan will be blocked off for approximately two weeks for site preparation and concrete pouring, then will need one week to cure and harden.

the goal is to open the south lane for traffic to pass while the concrete cures.
