Winter storm blankets Philadelphia in snow; students to learn virtually Tuesday WPVI Replay Video UP NEXT The Philadelphia Streets Department has deployed 450 pieces of equipment to keep roads passable after Monday's winter storm. The storm rolled in Sunday, but crews started brining roads on Friday in preparation. By Monday morning, ruddy snow had accumulated on residential roads, despite crews' best efforts. "Our goal is to make the roads as possible and return the city back to its normal operations as quickly as possible," said Philadelphia Streets Commissioner Carlton Williams. "This does not mean our roads will be completely clear of snow and ice but it may passable for safe travel."
