Truck Routes - mattyschell/nyc-spatial-rolodex GitHub Wiki
The New York City Department of Transportation designates local and through truck routes and releases a spatial file for these routes based on the single line street network (Lion) dataset.
The Department of Transportation releases these files periodically, with a major release in 2014 and again in 2019.
For more information, including a nice double-sided full color map of truck routes, take a look at the Department of Transportation Office of Freight Mobility page: https://www1.nyc.gov/html/dot/html/motorist/trucks.shtml
