The northbound lanes of I-29 near mile marker 97 in Holt County were shut down just after 4:00 P.M. after state troopers say there was a four vehicle accident involving two semi's.
The accident happened when icy road conditions led a semi truck driven by Jeoffrey A. Jones, 56, to jack-knife and block the northbound lanes, leading to a pile-up involving two cars and a second semi driven by David W. Hays, 61.
Hays was taken by ambulance to Heartland Regional Medical Center where he is being treated with serious injuries. No other injuries were reported in the accident.
Another accident happened before 8:30 P.M. Thursday night on the 66 mile marker of Interstate 29 when icy road conditions led Oregon, MO resident Ashley J. Hollis, 24, to lose control of her Jeep Cherokee and strike a Sterling Conventional driven by Vernon R. Schuchard, 48.
Hollis was taken to Heartland by a private vehicle to be treated for minor injuries. Schuchard was not injured in the accident.
The highway is now back open.
