Motorists can expect a number of road closures and heavier-than-normal traffic as thousands of runners and visitors descend on Duluth and the surrounding area for the 45th annual Grandma’s Marathon this weekend.
The most significant delays will likely be related to the ongoing Twin Ports Interchange project, which reduces Interstate-35 into and out of Duluth to just one lane in each direction between Garfield Avenue and 40th Avenue West. Organizers are asking everyone, whether you’re involved with the race or not, to expect and plan for congestion and traffic in that area as the weekend gets closer.
