Description: Starting on the 2016-2017 snow season, DSNY has instituted the use of new snow priority designations (critical, sector, haulster) to better manage the snow plow operations in New York City.Critical Routes: These routes are comprised of highways (main beds, entrances, exits interchanges), arterial roadways, main travel thoroughfares (single lane and multi-lane), bus routes, that contain emergency services & first responder facilities (Hospitals, EMS, FDNY, NYPD) and schools.Sector Routes: Designed to encompass all streets that are not classified as Critical Streets and are wide enough to accommodate a full size DSNY collection truck with a plow attached.Haulster Routes: Designed to service dead ends and streets that cannot be serviced with a collection truck or salt spreader with a plow attached due to narrow street width or tight turning radius (either entering or exiting the street).
