Cheyenne River flooding causes crevice to form on Wilsey Road
PENNINGTON COUNTY, S.D. — In addition to a roughly 31-foot deep sink hole that formed on Whitewood Street in Rapid City, a crevice has appeared on Wilsey Road north of Wall.
According to Pennington County Highway Superintendent Joseph Miller, the fissure is at a point in the road that comes very close to the Cheyenne river. He says the river’s swollen water levels have eaten away at the river bank, causing the road to split away as well.
Officials believe it started forming Thursday night and into Friday morning.
The road has been closed and all residents impacted have been notified. Miller says motorists are able to use a detour that runs along Ash Creek Road.
Flooding along the Cheyenne River has also led to severe damage to infrastructure farther north on the Cheyenne River Reservation. On Wednesday tribal officials issued a state of emergency, citing several road closures that have disrupted travel and posed safety hazards.
