ST. PAUL — The Memorial Day weekend is approaching and summer construction roadwork around the state is getting into full swing. The Minnesota Department of Transportation urges motorists to use extra caution while driving through highway work zones.

Sue Mulvihill, deputy commissioner and chief engineer, said MnDOT suspends work on most projects during the holiday weekend, but cautions drivers to be alert.

“There are still many work zones around the state where drivers need to plan ahead, pay attention and slow down to make it a safe weekend for everyone,” she said in a press release.

Motorists should be prepared for slower moving traffic and use extra caution in highway work zones. Plan ahead, think about alternate routes and go to www.511mn.org before leaving home to get information about road construction and detours.

In particular, Twin Cities travelers heading to Alexandria, Detroit Lakes, Fergus Falls and other areas of northwest Minnesota may encounter major delays along Interstate 94 for several resurfacing and reconstruction projects. Motorists on eastbound I-94 from northwest Minnesota to the Twin Cities should consider using Highway 55.

Motorists should consider avoiding the time period between 11 a.m. and 8 p.m. on Sunday and Monday for eastbound I-94 near Collegeville/St. John’s. Significant delays are expected with only one lane of lane traffic open through September 2016.
