In June, GeoStabilization received a phone call about 7:30 am that KY 221 had slipped down the hillside creating a large drop in the pavement. This closed one whole lane and a portion of an adjoining lane. KY 221 is the major traffic route between Harlan and Pineville, Kentucky, with consistent, heavy traffic. GeoStabilization was the first to arrive at the site. There was no traffic control and vehicles had no advance warning of on-coming traffic. GeoStabilization immediately began providing traffic control until KYTC’s personnel arrived and took over.
After consulting with KYTC’s engineers, GeoStabilization was able to implement an approved emergency stabilization proposal and started work that day. KYTC’s crews filled the inboard ditch with millings, which allowed vehicles to navigate safely with one-lane opened in each direction. The emergency work was completed within 10 days and, once the road was reopened, traffic started flowing as usual.
