What Are Some Facts About the Garden State Parkway?

New Jersey's Garden State Parkway is a 172.4-mile toll road that stretches the length of the state, from the New York state border to New Jersey's southernmost point, Cape May. The Parkway is the busiest toll road in the United States. The state of New Jersey began construction on the Garden State Parkway in 1946.

The speed limit on the Garden State Parkway is 65 miles per hour in most places. In others, it is 55 mph. All vehicles are allowed on the parkway, but commercial vehicles are prohibited north of exit 105. The Garden State Parkway connects with the New York State Thruway at Ramapo in Rockland County, New York. The major junction on the south end is Route 109 in Lower Township, New Jersey. Many of the entrances and exits on the parkway require a fee, and the Parkway implemented EZ-pass electronic toll collection in 1999.

The parkway's designer and engineer, Gilmore David Clarke, planned the parkway with design elements from the Pennsylvania Turnpike and the German Autobahn routes of the 1930s. The parkway was planned to provide fast, safe travel to the coastal resort towns and to meet the needs of residents in the northern commuter towns.

The Garden State Parkway is maintained by the New Jersey State Turnpike Authority, which posts traffic alerts and project information on its website.
