It's an art fair doubleheader in Minneapolis where the handiwork of regional and national artists will be on display, but it won't be picturesque on the roads.

Motorists will find lane closures on Hwys. 100 and 280 and a complete shutdown of I-35E south of downtown St. Paul.

The Fremont Avenue Bridge over the Midtown Greenway in south Minneapolis is closed indefinitely to motor vehicle traffic. A safety drill will take Blue Line light-rail trains offline from 11:30 p.m. Sunday to 3 a.m. Monday. Buses will fill in between the Fort Snelling and 46th Street stations.

In Eden Prairie, the Shreya R. Dixit Memorial Foundation will hold the ninth Raksha Walk/5K Run for Distraction-Free Driving at the Purgatory Creek Recreation Area. Central Avenue in northeast Minneapolis will be closed from Lowry Avenue to 18th Street for an Open Streets celebration Sunday from 11 a.m. to 5 p.m. Sunday.
