HARRISBURG – Gov. Tom Wolf is urging motorists to avoid unnecessary travel and encouraging employers to offer telework options if possible, as winter weather conditions are expected to worsen today. Vehicle restrictions are currently in place on several PA interstates and PennDOT anticipates that additional restrictions will be added as conditions warrant. Motorists are encouraged to sign up for personalized alerts and find the latest restriction and travel information at 511pa.com. Main roads are snow packed and slick. Secondary and back roads are the most challenging. If you don’t have to be on the roads today, stay put, so road crews can work on keeping roadways driveable. If you must travel, slow down and allow extra travel time. Snow emergencies have been declared in a number of towns.
