Several sections of Interstate 81 in Schuylkill County were closed Sunday morning after a surprise snow squall made driving all but impossible. The interstate was closed north bound at the one hundred mile marker just south of Pine Grove. The south bound lanes were closed between the 112 to 107 mile markers. Driving was treacherous between Mahanoy City and Frackville with a large accumulation of ice covering the roadway. COPYRIGHT LARRY NEFF/SPECIAL TO THE TIMES NEWS
