The Minnesota Department of Transportation is building an intersection designed to cut down on crashes at the intersection of Hwy. 65 and Viking Boulevard in Ham Lake.

The state has about a dozen intersections where drivers traveling straight across the highway or turning left are directed to turn right onto the highway. Then drivers make a U-turn at a marked opening in the median to get where they were going. The one that will bring lane restrictions on Hwy. 65 in Ham Lake this weekend comes with a new twist: It will be the only one with a stop light.

It’s called a reduced conflict intersection or a U-turn intersection, J-turn intersection or a Michigan left turn, since the intersections are common in that state.

Due to expected inclement weather, Metro Transit has called off weekend maintenance planned on the portion of the Blue Line between Target Field and Franklin Avenue stations and the Green Line between Target Field and Stadium Village. Service will run as usual.

It’s Art-A-Whirl weekend, so expect extra traffic on streets near the 60 locations in northeast Minneapolis where artists will display their wares. Other traffic-generating events include a Cher concert Saturday night at the Xcel Energy Center in St. Paul, the Twin Cities Heart Walk on Saturday morning at Target Field and a Minnesota United game at 7 p.m. Saturday at Allianz Field.

Here are some of the cone zones that may snarl traffic:
