UPDATE: Crews begin stabilizing sink hole on Whitewood Street
UPDATE (May 31, 2:00 p.m.) — City crews have started backfilling the sink hole that began forming on Whitewood Street on Thursday. They expect the process of filling and stabilizing it to last into next week based on the hole’s depth.
“We are continuing our investigation and it’s important we get in there and stabilize the sink hole,” said City Public Works Director Dale Tech. “The sink hole remains active with episodes of erosion taking place beneath the road surface.”
Crews will fill the hole initially with rock material and then eventually dirt. A temporary gas line is being installed Friday afternoon to restore gas service to a duplex in the area. It is the only residence that’s been impacted by loss of service.
Traffic remains closed in the vicinity of the sink hole, impacting the 300 block of Whitewood Street and the 2700 and 2800 blocks of West Omaha Street. The public is reminded to respect the security fencing and boundary perimeter around the sink hole. City officials say residents in the area can expect a larger volume of truck traffic hauling material this weekend and into next week.
UPDATE — The sinkhole on Whitewood Street continues to grow. Official measurements were taken Friday morning once the area was stabilized, according to Darrell Shoemaker, Communications Coordinator for City of Rapid City. The sinkhole is now about 24 ft. by 29 ft. in diameter and about 31 ft. deep. Officials originally thought the depth was closer to 40 ft. due to water gathered at the bottom.
Shoemaker says this is still an active situation as the road continues to collapse and even grew overnight. As officials work to come up with a plan of action, they ask that pedestrians and traffic avoid the area. Whitewood Street between West Omaha and West Rapid Street, as well as, National Street and Sturgis Street will remain closed until further notice.
“Still no definite cause at this point. We have pretty much ruled out any infrastructure issues. Looking at perhaps some natural causes. Whether or not that involves the precipitation. Precipitation may have been a contributing factor but again we’re visiting with some of the consultants we have on contract and kind of defining that more astutely at this point,” said Shoemaker.
