Providence Highway does not stop for weather; it only gets quieter and whiter. Boston Work Pro runs Norwood through the middle of a storm — parking lots pushed back, driveways opened, entries and walkways cleared, salt and sand laid where the plow leaves glaze. The best hours are the loneliest ones, two and three in the morning, headlights and falling snow and a lot coming clean in long straight passes. By the time the first cars turn in off Route 1, the pavement is dark and the curb lines are visible again. Norwood, with clearing out to Dedham, Canton, Westwood, Walpole and Sharon.
