The Minnesota Department of Transportation will shut down both directions of Interstate 94 in Minneapolis for 18 hours over the weekend to repair two bridges that were damaged when they were hit by a truck last summer.

Crews will straighten beams on the 25th Avenue bridge and replace the 22nd Avenue pedestrian bridge near Augsburg University with a temporary wooden-deck structure during the closure planned from 10 p.m. Saturday until 4 p.m. Sunday.

The closure kicks in after Saturday's University of Minnesota football game and should be done before the Timberwolves home opener Sunday. But it will make it tougher for fans heading to the Xcel Energy Center where the Wild are home Saturday night and Sesame Street takes over the arena Sunday afternoon.

It would not be Halloween without the big celebration in downtown Anoka, and parades and a 5K run will bring street closures there Saturday.

Here is where motorists will find ongoing construction projects, weather permitting:
