PRESS RELEASE – (from PennDOT) – With wintry weather predicted to affect much of East Central Pennsylvania tomorrow (Friday, March 20, 2015), PennDOT’s Engineering District 5 today urged motorists to spring into action by using caution and allowing extra time to reach their destinations.

“We have 209 plow trucks and approximately 20,000 tons of salt on hand to treat state roads in this region’s six counties tomorrow,” Assistant District Executive for Maintenance Jill Krause said. “We understand people are excited about the arrival of spring tomorrow evening, but tomorrow morning and throughout the day wintry conditions are predicted and we urge motorists to slow down, increase following distance and use caution.”

PennDOT operators use air and road temperature sensors in their plow trucks to determine what treatment material is best given the type of precipitation and temperature.

During storms, interstates and expressways are PennDOT’s primary focus and equipment may be redirected to these routes during significant winter events.
Plow trucks will also be slowed when facing heavy precipitation or when many other vehicles are also on roadways. This means that during heavier storms, motorists may find deeper accumulations on less-traveled routes and should adjust their driving for those conditions.

How often roadways are plowed or treated with salt and other material depends on a road’s traffic volume. On interstates and expressways, PennDOT aims for its plow trucks to pass by the same point on a plow route every two hours.

For other major roadways the department’s goal is for trucks to pass by the same point every two or three hours. On lower-volume roadways the department’s goal extends to every three to four hours, with less frequent cycles on roads with the lowest traffic volumes.
