Crews were planning to work through the night on Wednesday to make state highways passable for what was expected to be a messy morning commute, after a night of heavy snow and freezing rain forecast for much of the state.

“This is the first major snowstorm event for this season,” said state Highway Administrator Frank DePaola. “So we’re calling in our [state transportation department] employees, and we’ll also be calling in contract equipment to support us.”
