Numerous travel restrictions have been implemented across Pennsylvania as winter weather approaches. Interstates 90 and 86 are closed in Erie County due to severe weather conditions, with additional travel restrictions affecting routes from the Ohio-Pennsylvania border to New York. PennDOT has urged drivers to exercise caution on highways and prepared for snow over the holiday weekend. Speed limits have been reduced and restrictions on commercial vehicles are in effect on various interstates, while some restrictions have been lifted following recent storms. PennDOT officials remind drivers to be prepared for snowy conditions and provide safety tips for winter driving.
