The Garden State Parkway is a 172.4-mile (277-km) limited-access toll parkway that stretches the length of New Jersey from the New York state line at Montvale, New Jersey, to Cape May at the southern tip of the state. Its name refers to the state nickname, the "Garden State". Most New Jersey residents refer to it as simply "The Parkway". The Parkway's official (unsigned) designation is Route 444. The highway connects to a short segment of the New York State Thruway known as the "Parkway Extension" and which is officially designated (but unsigned) as New York State Reference Route 982L. That 2.4 mile segment connects to the Thruway mainline. According to the IBTTA, the Parkway is the most heavily traveled highway in the country.
