The Minnesota Department of Transportation closed Minnesota Highway 1 from Oslo to County Road 17 due to flooding on Wednesday, April 8. Highway 220 north of Oslo between Highways 1 and 317 also remains closed. With road closures in effect, the town of Oslo is essentially an island until Red River levels recede.

An April 7 executive order from Minnesota Gov. Tim Walz activated the Minnesota Army National Guard to provide assistance for the flood in Marshall County, and on Wednesday, April 8, nearly 20 soldiers from the Moorhead-based 2nd Combined Arms Battalion 136th Infantry mobilized to Oslo. They will assist with monitoring levees and flood protection systems as well as support any necessary rescue and evacuation operations, according to a release from the National Guard.

This is the second consecutive year the Minnesota National Guard has been sent to assist with flooding in Marshall County.

Oslo Mayor Erika Martens said like last year, the National Guard will assist in bringing supplies in and out of the town, including residents’ mail.

“So we will get the mail in and out, any kind of supplies that need to come in and out, whether it’s for the grocery store or for the restaurant or the bar, whatever is needed,” Martens said. “They will help transport materials, any and all kinds of necessities that are needed.”
