A crash on the Will Rogers Turnpike near Adair Friday morning caused all or parts of the roadway to be closed for more than seven hours.
It happened shortly after 4:00 a.m. in the westbound lanes of the turnpike just south of Big Cabin. That's about 50 miles northeast of Tulsa near the Mayes/Craig county lines.
According to the official report from OHP, 24-year-old Timothy Michael Murphy of Owasso was driving a 2000 Freightliner eastbound on the Will Rogers Turnpike when he ran off the right side of the roadway, overcorrected, and went through the center retaining wall.
The trailer remained on the eastbound side of the turnpike, while the cab went onto the westbound side, OHP said.
OHP said Murphy's semi was then struck by a 1998 Kenworth driven by 60-year-old Ioan Inderisan of Parma, Ohio.
Inderisan's Kenworth was then reportedly struck by a 1997 Jeep Cherokee driven by 25-year-old Steven Vann of Waynesville, Missouri.
OHP said Vann's Jeep was then struck by a 2005 Freightliner driven by 51-year-old Terry Roberts of Sedalia, Missouri.
The collision resulted in the entire roadway being blocked. One eastbound lane was re-opened at about 6:00 a.m., and the entire roadway reopened at about 11:30 a.m.
Murphy was taken by Tulsa Lifeflight to Saint John Medical Center in Tulsa in poor condition with head, arm, leg, and torso injuries.
Inderisan and his wife, 62-year-old Viorica Inderisan, were taken by Mercy Regional EMS to Craig General Hospital in Vinita in good condition with injuries.
Vann was taken by Air Evac to Saint Francis Hospital in Tulsa in poor condition with head injuries.
There were no updates on the conditions of any of the drivers as of 6:00 p.m. Friday.
