Four roads were closed Tuesday in rural Pennington County due to flooding, and officials said more closures could come.
Pennington County Highway Superintendent Joe Miller said that 156th Avenue by Box Elder between Highway 1416 and Lonesome Dove Street was closed due to the high water, as were a stretch of 155th Avenue south of Highway 1416, Antelope Creek Road from East Highway 44 south to Dawkins Road, and Big Foot Pass Road from Interstate 90 to Highway 240. Big Foot Pass is a north-south road about 10 miles east of Wall between Quinn and Cottonwood.
Miller said a combination of high water volume and cold temperatures froze culverts. That meant the water can’t pass under the ditch, so it spilled out over roadways.
He cautioned motorists to avoid the flooded areas and give highway crews ample space to try to clear the culverts and get the roads open.
“Do not drive through the water,” he said.
Highway crews were busy with heavy machinery on 156th Avenue on Tuesday morning trying to clear ice jams in hopes of alleviating some of the flooding.
Much of South Dakota and Nebraska have been dealing with intense flooding since last week’s massive blizzard that dumped rain and snow across a region already deluged.
