Along the Route 15 corridor the lots run wide and the trucks come regardless of weather, so Belleville's commercial snow has to go somewhere. SSE HAULING plows it, stacks it and hauls the piles away once the banks start eating parking spaces, then clears entries, walks and dock aprons and lays salt where traffic packs it slick. Working a snowstorm at night has its own odd calm: headlights, steam off the exhaust, an acre of white going back to gray. By opening time the painted lines show again and every door is reachable. That is the shape of the whole winter, one push at a time.
