GARVIN COUNTY, Okla. (KTEN) — Five big rigs and two passenger vehicles were involved in a major accident on Interstate 35 near Davis on Wednesday afternoon, backing up traffic for miles.

The Oklahoma Highway Patrol said at two people in a Honda Accord were killed when their car was crushed by the impact of the crash in the northbound lanes at Mile Marker 59, north of the State Highway 7 interchange. It took five hours before the Wynnewood Fire Department could remove their bodies.  

Their names were not released.

Investigators said four 18-wheelers and two other vehicles were stopped shortly after noon because of congestion in a construction zone.

A Volvo tractor-trailer driven by Tony Aghaji-Enweremadu, 38, of West Palm Beach, Florida, "failed to stop and struck all of the other units," OHP Trooper Ryan Hayes said in a written statement. Aghaji-Enweremadu was airlifted to a hospital in Denton, Texas, for treatment and was later released. 

One other truck driver was hospitalized with injuries.

It took more than eight hours for all the wreckage to be cleared and for all lanes of I-35 to be reopened to traffic.
