The rule
Bicycles are prohibited on Interstate highways in New York. Bicycles are prohibited on New York State Interstate highways under NYSDOT controlled-access regulations and on the New York State Thruway (I-87, I-90), the Garden State and Cross-Westchester Expressways, and most NYC-area parkways. The Hudson River crossings have specific bicycle rules — see the Port Authority and MTA bicycle access pages for the Verrazzano-Narrows, George Washington, and Bear Mountain bridges. Conventional US and state routes (US-9, US-20, NY-9W) remain open.
What this means in practice
Stick to surface streets, US routes, state highways, and dedicated paths. If your route in New York appears to use an Interstate, plan a detour before you start.
