 MnDOT says Interstate 35 West is closed in both directions at I-494 in Richfield and Bloomington. That's to allow work crews to demolish a freeway bridge. Part of eastbound 494 also is closed in the same area. Traffic is being detoured using Highway 62 and 77. Also this weekend, westbound Highway 36 is closed between Interstate 35 East in Little Canada and I-35 West in Roseville for a resurfacing project.
