We've had mountains of snow (mostly at intersections) created by plows during and after the big blizzard back in December. Freezing temperatures kept the snow frozen for much of the past 3 weeks. Now that the temperature is above freezing, DSNY is on a mission to break down these mountains. One truck pushes a bunch of snow into the middle of the street. The following truck then spreads the snow over a wider area. Passing traffic does the rest of the job by crushing it until it eventually disappears. Magic.
