Slippery road conditions are causing massive delays and crashes throughout the Delaware Valley Sunday, leading authorities to shut down several major arteries for a portion of the morning.
Authorities issued a warning Sunday morning that multiple highways, including I-95, I-76, the Vine Street Expressway and Roosevelt Boulevard, are all treacherous, and urged drivers to stay home and avoid driving.
"The most difficult part about this is that a flash freeze like this, the moisture can freeze on contact with the pavement," PennDOT spokesman Eugene Blaum said.
Rain combined with near freezing temperatures, causing an icy glaze on area roads.
"Conditions are improving in South Jersey as those temperatures rise," said Steve Shapiro of the New Jersey Department of Transportation. "One thing to be aware of though -- flooding could be an issue on some roadways."
