DENISON, TX-- Traffic was backed up for several hours Thursday afternoon, after a three vehicle accident involving a semi-truck on highways 69-75 near the Texas Travel Information Center.

Denison Police and Fire crews responded to the accident where 38-year-old Geoffrey Ewing II of Dallas, was transported by medical helicopter with possibly life threatening injuries.

Traffic was shut down in both the north and southbound lanes for nearly an hour.

The semi-truck was traveling in the northbound lane, before slamming into two other vehicles in that lane.

The driver of the semi, 51-year-old, Kenneth Bunton, of Missouri, told police he didn't see the slowing traffic in front of him.

His semi-truck traveled across the median and over the southbound lanes of traffic before coming to a stop in front of the travel center near the Texas, Oklahoma border.

TxDot staff was on hand to clear a diesel leak caused by the semi, which spilled nearly 100 gallons of fuel onto the road and grass near the travel center.

Denison Police say they did write Bunton, a 'failing to control speed' ticket.
