Streets cleared of snow in New York City as of
12:30 p.m. on February 8th
A blizzard came through the northeast during the first week of February 2013. The NYC Department of Sanitation posted a map showing when roads are plowed, updating every 30 minutes. The maps shown here illustrate 24 hours of that data, which I scraped starting just after noon on February 8th.

Dark lines indicate roads that were cleared of snow within the previous hour; lighter lines have gone longer since being plowed.
