An unlimited sinkhole in Hinton, West Virginia, that has threatened to swallow the city’s police station on Route 20 has spurred officers from the state Division of Highways to pour fill materials underneath the highway and begin building of a 120-foot bridge over the opening, per CNN.

The police division moved personnel from the constructing in July and expects the constructing will finally should be demolished, WVNS-TV reported. Fill materials proved to be a profitable answer for underneath the highway till rains from Hurricane Nicole earlier this month washed all of it out — and made the sinkhole even greater.
