Road and lane closures with their associated detours are not fun for anybody, and this weekend will be a dozy for drivers in the west metro, at least for those who didn't head out of town for MEA weekend.

Both directions of Hwy. 100 through St. Louis Park and Edina will shut down from Friday night to Monday morning. The good news is that the Minnesota Department of Transportation says this ought to be the last one for the season, and that the entire rebuilding project will be done "within a few week," the agency said.

Further complicating travel is that southbound I-494 through Plymouth and Maple Grove will be closed from 10 p.m. Friday until 5 a.m. Monday while only one northbound lane will be open between I-394 and Hwy. 55.

That will leave Hwy.169 as the only through north-south route open on the west side of the city.

Further to the west, Hwy. 12 remains closed between Wayzata and Orono for another two weeks while in the south metro drivers will find Cedar Avenue reduced to a single lane in each direction on the Minnesota River bridge.

Traffic generating events include a Timberwolves preseason game Friday night at Target Center. The U.S. Women's National Soccer Team takes on Switzerland Sunday afternoon at U.S. Bank Stadium. And it's Homecoming at the U, so look lots of festivities on campus, including the 6:30 p.m. Friday parade that will travel down University Avenue from 12th Avenue SE. to Oak Street. On Saturday, roads near TCF Bank Stadium will be closed before and after the 11 a.m. game against Rutgers.
