A tractor-trailer fire left Interstate 70 closed for more than an hour Tuesday evening.

It happened in the eastbound travel lanes at mile marker 13.5 in Ohio County, just west of the Pennsylvania state line.

The result: traffic backups for miles with hundreds of motorists sitting on the two-lane highway.

Firefighters at the scene say the truck was hauling a frozen vegetable puree smoothie mix.

The driver of the truck was injured while trying to put out the fire and was taken to Wheeling Hosptial for treatment.

Fire crews from Valley Grove, West Alexander and Triadelphia worked to put out the fire, experiencing difficulties along the way.

“The challenge on the interstate is the lack of water and you don’t ever know what the trucks are hauling,” said Valley Grove Fire Chief John Gearry.

With Stay At Home orders being lifted, more people are hitting the roads.

“The volume of traffic and the people that are out and about, our call volumes have actually been very low, which is a great thing,” said Chief Gearry. “But I do fear that we’re going to see an increase just because people haven’t been out. Just stay alert, don’t get distracted and pay attention.”

The highway reopened to traffic around 11 p.m. Tuesday evening.
