Two major highway closures in the Twin Cities are set to begin in the coming days, including a months-long closure of Highway 280 and a weekend closure of Interstate 35W in Burnsville. Southbound Highway 280 will be closed at 5 a.m. on April 29 for safety improvements and road and bridge repairs between Interstate 94 in St. Paul and Highway 36/I-35W in Roseville. Both directions are expected to remain closed until late August, with the closure expected to occur before the 2026 Minnesota State Fair.
