A spatial dataset containing arterial and major street routes from the New York City Digital City Map (DCM). This layer represents the primary road network designated as arterials and major streets for traffic planning and management.
Format
An sf object with 740 features and 7 fields:
- borough
Character. The borough name (Manhattan, Brooklyn, Queens, Bronx, or Staten Island)
- boro_code
Integer. Numeric borough code (1=Manhattan, 2=Bronx, 3=Brooklyn, 4=Queens, 5=Staten Island)
- route_name
Character. The name of the arterial or major street route
- route_type
Character. Classification of the route type (e.g., "Major Streets")
- route_sub
Character. Sub-classification of the route (e.g., "Major Street", "Major street to be improved")
- route_stat
Character. Current status of the route (e.g., "Existing")
- geometry
sfc_MULTILINESTRING. Spatial geometry representing the arterial or major street

Details
The coordinate reference system is NAD83 / New York Long Island (ftUS), EPSG:2263. This projection uses US survey feet as units.
Arterials and major streets form the backbone of NYC's street network and are important for traffic planning, emergency services routing, and understanding the city's primary transportation corridors.
