While you are sleeping Wednesday night, MnDOT crews will be busy fixing roads and working on a number of projects. Here is a sampler:

The Minnesota Department of Transportation will close both directions of I-35E between I-94 and Hwy. 36 from 9 p.m. Wednesday to 5 a.m. Thursday when it uses a technique called slide-in bridge construction to move the Larpenteur Avenue bridge into place.

The dike that was put up on northbound I-35W at Black Dog Road to prevent flood waters from spilling onto the freeway is coming down. The freeway will be reduced to a single lane from 7 p.m. Wednesday to 5 a.m. Thursday and motorists can expect delays between Burnsville Parkway and Black Dog Road.

A detour and lane restrictions will be in place for Crosstown drivers in Edina and Eden Prairie. At 11 p.m. Wednesday, westbound Crosstown will be closed at Hwy. 169. Motorists will be detoured onto northbound Hwy. 169 up to 394, then back south to the Crosstown.

Eastbound Hwy. 62 motorists will find alternating lane closures beginning at 8 p.m. at the Hwy. 212 junction with the Crosstown. The closures will allow crews to pour concrete for the southbound Hwy. 169 bridge deck over the Crosstown. Work will wrap up by 5 a.m. Thursday.

Here are a couple other night projects that will affect night owls:

Hwy. 55 between County Road 6 and County Road 73 in Plymouth. Expect intermittent lane closures between 7 p.m. and 5 a.m. No loads wider than 11 feet will be able to get through.

On southbound Hwy. 100, construction will have the highway down to one lane from 7 p.m. Wednesday until 7 a.m. Thursday.

Northbound I-35W in Minneapolis will be down to a single lane from the 11th Avenue overpass to the Mississippi River from 8 p.m. to 6 a.m. Wednesday and Thursday.
