Grandma's Marathon weekend is once again upon us and with all the races being sold out for the first time since 2016, the Northland can expect plenty of visitors and plenty of traffic throughout the weekend.

The Duluth Police Department sent out a full list of traffic advisories ahead of the 46th annual running of Grandma's Marathon, which should help both Northland residents and visitors navigate the area.

There are three total races that are a part of Grandma's Marathon weekend. The first is the William A. Irvin 5K, which begins at 6:00 p.m., but Harbor Drive behind the DECC will close to traffic at 4:00 p.m. Then, at 5:30 p.m., portions of Railroad Street will close to traffic for the duration of the race.

Other things to keep in mind for the William A. Irvin 5K include:

  • The Aquarium parking lot will not be accessible from 5:30 p.m. until approximately 7:15 p.m.
  • Access to the DECC during the race will be through the North Gate (on Railroad Street) or the East Gate (on Harbor Drive), from Lake Avenue or 5th Avenue West. Outbound traffic from the DECC will only be from the West Gate (5th Avenue West) from 5:00-7:30 p.m.
  • Vehicles on northbound I-35 exiting on the 5th Avenue West off-ramp can either continue straight to Lake Avenue to access the DECC Lot or turn right onto 5th Avenue West to access either the DECC Lot.
