Nebraska State officials have closed a portion of Nebraska Highway 12 just south of the South Dakota/Nebraska state line due to flooding of the Missouri River.
S.D. Highway 37 south of Running Water meets up with Nebraska Highway 12 on the other side of the Standing Bear Bridge over the Niobrara River. This essentially creates a dead end on S.D. Highway 37 as well as cuts off access to Niobrara, NE from this route.
Motorists will need to find an alternate route.
