The rule
Bicycles are prohibited on Interstate highways in New Jersey. Bicycles are prohibited on New Jersey Interstate highways (I-78, I-80, I-95, I-280, I-287, I-295, I-676) under NJDOT controlled-access regulations and on the New Jersey Turnpike, Garden State Parkway, and Atlantic City Expressway under their respective authority regulations. Conventional US and state routes (US-1, US-9, US-202, NJ-29) remain open. The Pulaski Skyway and the Hudson River crossings (Lincoln and Holland Tunnels, George Washington Bridge bike path) have separate rules — check the Port Authority bicycle access pages.
What this means in practice
Stick to surface streets, US routes, state highways, and dedicated paths. If your route in New Jersey appears to use an Interstate, plan a detour before you start.
