Ohio Will Fill Coal Mine That's Causing Highway To Sag

Google Maps

Ohio's transportation department plans to fill a vacant coal mine that's causing a heavily used highway in southeast Ohio to sag a bit.

Engineers say there's no immediate danger to drivers on U.S. Route 33.

The project beginning this summer will attempt to stabilize a 1-mile stretch that runs near the highway in Athens County.

Transportation officials say the void is causing a small dip in the westbound lanes of the highway just south of the Nelsonville bypass.

The estimated $4.5 million project is expected to be finished in 2017.

Workers will drill 40-60 feet down in and pump in a mixture of cement, fly ash, sand and gravel to fill the voids.
