NORRISTOWN, Pa. - PennDOT trucks loaded up piles of rock salt at the maintenance yard in Nicetown Tuesday while other crews were packing their plows for the first time in 20 months.After spending the day pre-treating hundreds of miles of highway with salt brine, 425 crews will now wait for the first flakes Wednesday afternoon.“We will switch over to salting operations once we get a coating or more.
And then clearing operations. We will drop the blades begin plowing operations once we get to an inch or two and we expect that to continue all through Thursday morning," PennDOT spokesman Brad Rudolph said.Motorists are getting ready, too.
