TRIADELPHIA — A tractor-trailer overturned Monday morning at the bottom of Two-Mile Hill on Interstate 70 — a spot near The Highlands notoriously dangerous for travel — rekindling the discussion of safe driving in that area of Ohio County.

Around 6:30 a.m. Monday a tractor-trailer carrying two trailers was traveling west down Two-Mile Hill, said Ohio County Emergency Management Director Lou Vargo, when the driver said he hit a slick patch and lost control of the vehicle. The tractor-trailer overturned at the bottom of the hill on the curve.

Vargo said the driver was able to walk out of the wreck and was not injured. The inside lane of I-70 West near the Highlands was closed for hours as crews righted the tractor-trailer and towed it away. The lane reopened Monday afternoon.

The Two-Mile Hill section of I-70 is one of the most treacherous in the county for multiple reasons. The slope of the hill is steeper than most sections. The curve at the bottom can topple large trucks if it’s taken too fast. And the on-ramp to I-70 West from The Highlands can get congested during peak traffic.

Add inclement weather — several inches of snow dumped in the Ohio Valley over the weekend — and traveling can get even hairier.

It’s not that Ohio County officials don’t warn drivers of the risks.

“We say to slow down,” he said. “We have electronic signs both ways informing about slippery conditions. But with good old gravity, that’s a lot of weight coming down there.”

Vargo said the county has used additional methods to slow traffic. The Ohio County Sheriff’s Office routinely patrols the area. An anti-slip material has been added to the interstate there to reduce crashes. Yet, Vargo said, an ice patch or layer of snow can lead to trouble.

Vargo said the best bet is for all vehicles, from small passenger cars to tractor trailers, to obey speed limits in the area, especially around the curve at the bottom of the hill.

“That’s also not the place to be changing lanes,” Vargo said. “If somebody’s slowing down in front of you, just slow down. We see drivers, not only tractor trailers but everybody, weaving in and out in that section.”

And if a crash does happen and public safety vehicles are closing a lane, Vargo said, it’s important for motorists to slow down around the crash site, especially when first responders are pulling people out of vehicles.

“When you’re approaching an accident and you see police cars, sheriff’s deputies and fire trucks blocking a lane and moving you into another lane, just because it’s called a fast lane doesn’t mean you go fast.

“It was unbelievable (Monday) that, in icy conditions, people were moving into the other lane and still going 55 or 60 miles an hour past us,” Vargo said. “And we’re getting the driver out of the vehicle. So heed emergency vehicles. They’re not blocking a lane for no reason.”
