North Dakota DOT closed Interstate 94 from Jamestown to Bismarck during the night. There are numerous spots that are under water. If you need to travel in that direction, use alternative routes and check the DOT road report site. http://www.dot.nd.gov/roadreport/roadreport/roadreport.asp
A stretch of I-94 between Oriska and Tower City is also under water. National Guard and Highway Patrol are directing traffic through the water. Expect delays if you travel in that area.
