ROSTRAVER TOWNSHIP (KDKA) — PennDOT in Westmoreland County was busy treating any slush that remained on secondary roads or ramps because of a concern that wet roads would turn to ice before Wednesday morning’s commute.

“The temperatures are expected to be very cold, and the water that is currently on the roadways in areas will freeze,” said Tim Cook from PennDOT Westmoreland County.

Cook said even with crews working all night, “There might still be freezing, even though we’re treating the roads. You might see icy areas, especially on the secondary roads.”

He said road salt works in the colder temperatures, but the temperature is going down so low Tuesday night that it becomes less effective, which means crews have to use more of it.

“Below 20 degrees, salt loses its melting capacity, but it still will melt ice just not as much ice,” said Cook.

He advises drivers using secondary roads Wednesday morning to stay alert.
