The driver of a semi truck died early Monday when he crashed into an overturned semi sprawled across both eastbound lanes of Interstate 90 six miles east of Wall, according to the South Dakota Department of Public Safety.
Two people from inside the overturned truck exited safely before the impact. They were treated at Rapid City Regional Hospital and released.
The name and identity of the 65-year-old driver killed was not released, pending notification of family. The names of the other driver, age 29, and his passenger, 27, both men, were also not released.
No other vehicles were involved. Tremendous debris from the accident shut down both eastbound lanes of I-90 for several hours, causing detours.
The crash occurred at 5:22 a.m. when the 29-year-old driver lost control of his 2014 Volvo semi truck and overcorrected, causing the tractor and trailer to tip over across both eastbound lanes, investigators said. The second driver died when his 2010 Freightliner, pulling double trailers, crashed into the first. He was pronounced dead at the scene.
The South Dakota Highway Patrol is investigating the crash. Other agencies on scene were the Pennington County Sheriff’s Office and Wall Ambulance.
