 A busy road in Duluth will be closed for three weeks starting tomorrow. St. Louis County says Woodland Avenue between St. Paul Avenue and Northfield Street will be closed through traffic to allow crews to work on storm sewers, curbs, gutters, and sidewalks. That closure runs through July 30th. The work is part of a larger summer-long project along Woodland Avenue in Duluth, which includes changing the road from two driving lanes in each direction to one with the addition of a center turn lane and a bike lane.
