Landslide closes part of River Road; third road slide in recent years | Local News for Bismarck-Mandan, North Dakota
BISMARCK STAFF TRIBUNE
A landslide closed off part of River Road north of Bismarck.
The two-lane road was closed Friday night from Sandy River Drive to Wilderness Cove Road, according to Burleigh County Emergency Manager Mary Senger. There were no injuries or vehicles damaged.
“The barriers caught the slide,” she said.
The landslide is still active and officials are monitoring the situation, Senger said. There was no immediate estimate of when the road might reopen.
“We will have more information next week after more (aerial) photos and a review,” Senger said.
This is the third landslide on River Road in recent years. One in December 2019 closed the road in the northern Bismarck area, blocking the two lanes between block 3800 in the north and block 4000 in the south for eight days. A landslide in March 2020 caused a shorter road closure between Sandy River Drive and Wilderness Cove Road. No one was injured and no vehicles were damaged in either incident.

The Burleigh County Commission in 2020 approved that an engineering consultancy firm study the road and provide a solution to the landslides. Commissioners then put the project on hold due to state aid uncertainty following the coronavirus pandemic.
Last year, the city rehabilitated the roadway and improved grade stability north of the Grant Marsh Bridge to address the Bismarck portion of River Road. The reconstruction between Keelboat Park and Burnt Boat Drive cost $1.1 million.
