The first full weekend of fall serves up a variety of traffic-generating sporting events, concerts and festivals, but road work could make it challenging to get to the fun.

The University of Minnesota homecoming parade Friday night, plus a Gophers football game Saturday and a Vikings game Sunday at TCF Bank Stadium will bring extra traffic on roads leading to campus. Meanwhile, downtown Minneapolis will be busy with a Shania Twain concert Saturday night at Target Center. Downtown St. Paul will see an influx of traffic Sunday night for the Wild hockey game at the Xcel Energy Center.

Off the mainline, the Walk to End Alzheimer’s will close streets near Target Field Saturday morning. The final Minneapolis Open Streets event takes over Lowry Avenue Sunday afternoon.

Here are places travelers will be forced to detour this weekend.

• The weather should be nice for the Minnesota Department of Transportation’s bridge painting project, which will shut down the southbound lanes of Interstate 494 and all entrance and exit ramps between I-694/94 split and I-394 from 10 p.m. Friday to 5 a.m. Monday. The official detour: Eastbound I-694/94 to southbound Hwy. 169 to westbound Hwy. 212 to I-494.
