POTTSVILLE, Pa.—A stretch of an interstate highway in Pennsylvania remained shuttered Tuesday, a day after at least three people were killed and more than a dozen others injured when tractor-trailers and other vehicles lost control and slammed into each other during a snow squall.
Interstate 81 north remained closed early Tuesday morning following the wreck Monday morning amid poor visibility that involved between 40 and 60 vehicles, authorities and published reports say.
