The shutdown of two — yes, two — segments of Interstate 35E this weekend will likely throw motorists and their GPS systems into a tizzy as they search for alternate routes to send them around the closures and away from prescribed detours that feature constructions zones of their own.

Both directions of I-35E between Interstate 94 in downtown St. Paul and Shepard Road and further north from County Road E in Vadnais Heights and County Road 14 in Hugo are shut down until 5 a.m. Monday. In the west metro, northbound Hwy. 100 through Edina, St. Louis Park and Golden Valley is closed.

Leaving town might not provide much relief, either. The Minnesota Department of Transportation is warning about backups and slow traffic on I-35 between Hinckley and Pine City, bad news for those heading to and returning from Grandma's Marathon in Duluth. Bridge painting could snarl traffic on I-35 between Northfield and Elko. Going northwest? Construction will slow down drivers on I-94 in Rogers and from St. Cloud to Collegeville.

Here in town, the North Star Bicycle Festival Sunday in Stillwater, Twins games at Target Field and a show featuring pop megastar Justin Bieber at Target Center Sunday night will generate traffic. Expect congestion around the State Fairgrounds for the annual Minnesota Street Rod Association's Back to the 50s weekend.
