At three in the morning the office campuses off Route 10 are the emptiest places in Parsippany: acres of black asphalt, a few tall lampposts, and snow falling through the light with nobody to watch it. Lio Construction LLC works those hours, plowing lots and drives, stacking piles where they will not block a sightline, and salting the lanes people cross from car to door. Big spaces reward a plan, because where the snow goes in the first storm decides whether there is room for it by the fourth. Walkways get opened too, along with the entries where slush always collects. By the time headlights start rolling in off the highway, the pavement is clear and the night's work is already behind them.
