"Can of Worms" highway ramps in Duluth to close July 14

Crews will perform preventative maintenance beginning Monday, July 14, on the highway ramps at the downtown interchange that serves Highway 53 (Piedmont Avenue), 21st Avenue West, Interstate 35 and I-535, according to the Minnesota Department of Transportation. The work on what is known locally as the "Can of Worms" interchange will require single-lane restrictions on Highway 53 (Piedmont Avenue) and complete ramp closures for 21st Avenue-West.

Ramp closures should not last more than one day, and should not significantly affect traffic access to Highway 53, I-35 and I-535. Motorists are advised to use alternate local routes between 21st Avenue West and Highway 53. This highway improvement project is estimated to last five days, depending on weather conditions.
