In a rare move, the Minnesota Department of Transportation will shut down a major metro area highway on a holiday weekend.

Both directions of Hwy. 100 will be closed from Saturday morning to Tuesday morning between Hwy. 7 and the Crosstown Hwy. 62. Crews using cranes will be moving a railroad bridge as part of the $2 billion Southwest light-rail project.

Twin Cities & Western Railroad is not running trains from noon Sunday to early Tuesday, which made it “an ideal time” to move the bridge, said SWLRT spokesman Trevor Roy.

MnDOT typically does not allow full highway closures on holiday weekends, but “to keep this project moving forward, we made the exception,” said MnDOT spokesman David Aeikens.

Drivers who normally use Hwy. 100 to detour around the closure of the northbound I-35W to westbound I-94 ramp will be directed to Hwy. 169, Aeikens said.

With this being the last summer hurrah for many, those hitting the roads will find the lowest Labor Day gas prices since 2004, according to the gas price tracking app GasBuddy. On Thursday, Minnesota had some of the lowest gas prices in the nation at $2.12 per gallon, according to AAA.

Law enforcement continues its extra drunken driving enforcement through Monday.
