Sandstone Mountain is the long grade on Interstate 64 in Raleigh County, West Virginia, about 12 miles east of Beckley. The eastbound and westbound lanes split and cross the ridge at two different summits, so the climb you remember depends on which way you are headed. Eastbound is the one that gets trucks in trouble. It is signed and described as a 7% grade, and over the full run it averages roughly 5.9% across about 4.6 miles, dropping near 1,433 feet (crashforensics.com). The mandatory truck pull-off sits at the Bragg exit near the summit, and the mountain itself lies between about mileposts 129 and 139.
This is one of the steepest stretches of interstate in the state, and the traffic is heavy. WV DOT officials put the count between 1,700 and 2,000 trucks down the grade every day (truckinginfo.com). A long, sustained descent like this heats brakes, and overheated brakes fade. The truck speed limit is 45 mph for anything over 26,000 pounds, while cars run 70 (truckinginfo.com; crashforensics.com). Two emergency escape ramps were built on the eastbound side, and they get used.
West Virginia does not run a western-style chain-control program, so there is no chain season here and no named chain-up area. What Sandstone has instead is a mandatory brake-check stop at the top. Truckers stop, inspect, and let the brakes cool before they start down. For winter conditions and current closures, the verifiable official sources are WV 511 and NWS Charleston.
