The City of Duluth is planning to reconstruct Superior Street, including all underground utilities, from 7th Avenue W to 4th Avenue E. The existing brick pavers, installed over 20 years ago, are at the end of their lifespan. In 2013, portions of the bricks were removed and replaced with asphalt due to the extent of deterioration. This temporary solution was initiated with the understanding that a long-term design process would be undertaken.
The revitalization project includes replacing and repairing public utilities, improved pedestrian connections, wayfinding, new streetscape and lighting as well as increased amenity space.
Superior Street from 7th Avenue West to 4th Avenue East will be reconstructed over the next three construction seasons.
2018: 7th Avenue West to west side of 3rd Avenue West intersection
2019: 4th Avenue East to east side of Lake Avenue intersection
2020: Lake Avenue to 3rd Avenue West (includes both intersections)
On-street parking will not be available in the section of Superior Street that is under construction. Motorists are encouraged to utilize parking ramps during this project, though on-street parking still will be available along the avenues as well as other parts of Superior Street and neighboring streets. Seven parking ramps will be offering “First Hour Free” parking for motorists!
The following ramps are recommended during each phase:
The utilities underground date back to the 1880’s. The contractor needs to set up temporary water service first which will require some digging to access underground water lines. Water service may be disrupted for a few hours when the connections are being made, but property owners will be notified ahead of time.
Once temporary water is set up, we will be using heavy equipment to start removing surface material layer by layer to access each utility.
The utilities closest to the surface are the fiber networks for cable and phone.
Below fiber lies the water, steam and gas lines. Sanitary sewer lines are at the lowest dept of about 10-12 feet. Those were secured with a cured in place high density plastic liner last year to ensure its integrity.
Detours will be indicated by on street signage within the project zone. Leading into downtown, motorists will see a Superior Street closure notice on the Department of Transportation digital board.
The public can also plan ahead and check the City’s “Road Closure” map available online at www.superiorstreet.org/parking-skywalk/ Road closures and detours will be noted on the map. This website also has a map with the parking ramps and skywalk connections identified.
The City of Duluth has been working with the Greater Downtown Council and a Communications Taskforce group to develop marketing plan and wayfinding signage that will be placed at street level and skywalk level listing the accessible businesses or organizations on the street or sidewalk level.
There will also be standard construction boards directing traffic to detours, parking or road closure information. The Greater Downtown Council is enlisting its Clean and Safe Team as Construction Navigators to assist the public during the project.
Buses: The Duluth Transit Authority will reroute their Superior Street pick up and drop off zones to Michigan Street and First Street. Their detour schedules are available at www.duluthtransit.com
