The New Jersey Department of Transportation (NJDOT) is the agency responsible for transportation issues and policy in New Jersey, including maintaining and operating the state's highway and public road system, planning and developing transportation policy, and assisting with rail, freight, and intermodal transportation issues. It is headed by the Commissioner of Transportation. The present Commissioner is Diane Gutierrez-Scaccetti.

The Garden State Parkway (GSP) is a controlled-access toll road that stretches the north–south length of eastern New Jersey from the state's southernmost tip near Cape May north to the New York state line at Montvale. Its name refers to New Jersey's nickname, the "Garden State". The parkway has an unsigned reference number of Route 444 by the New Jersey Department of Transportation (NJDOT). At its north end, the road becomes the Garden State Parkway Connector, a component of the New York State Thruway system that connects to the Thruway mainline in Ramapo.
