Foscoe Firemen and other emergency teams have cleared the scene where they spent the night working a tractor trailer wreck on Holloway Mountain road—a wreck that involved a truck carrying hazardous materials on the curvy road.  The call came in about 11:30 last night—that the truck overturned on the gravel portion of the road in the “S” curve—causing an out-of-county haz-mat team to respond from Hudson.   The truck and the hydrogen sulfide cargo were finally righted and the truck righted and safely removed.
