The Morton County Sheriff's Department and North Dakota Highway Patrol have shut down Highway 1806 indefinitely after protesters set up their own roadblock south of Fort Rice over the weekend.

Law enforcement convinced protesters to remove their roadblock peacefully, but they are worried it could reappear at any moment, and materials remain on the side of the road.

Highway patrol Captain Bryan Niewind says Sunday protesters set up a new camp on private property which they claimed by eminent domain and set up a roadblock of their own.

"Officers were able to engage the individuals that were creating this roadblock. We visited with them and eventually they removed those items from the roadway, but the ditches are still full of all those items that could easily be moved back into the roadway and blocked," said Niewind.

Protesters say they have claimed eminent domain over the new land, claiming that is the site of sacred burial grounds.
