CANONSBURG, Pa. — Snow squalls made for a busy day for road crews and had a serious effect on the Tuesday morning commute here in Washington County. Canonsburg officials say they got nine inches of snow. Crews started working around 11 p.m. on Monday to try to keep the roads clear with each round of snow. Canonsburg’s Borough Manager Angela Senay said it was a team effort to stay on top of the slow-moving band of lake-effect snow. Canonsburg’s director of streets said the borough went through 125-130 tons of salt on Tuesday alone as road crews prepare for the possibility of more snow.
