GSP meaning in Governmental ?

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 to the New York state line at Montvale. Its name refers to New Jersey's nickname, the "Garden State". The parkway is designated by the New Jersey Department of Transportation (NJDOT) as Route 444, although this designation is unsigned. 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. The parkway is the longest highway in the state at approximately 172 miles (277 km), and, according to the International Bridge, Tunnel and Turnpike Association, was the busiest toll road in the United States in 2006. The highway has a posted speed limit of 65 miles per hour (105 km/h) for most of its length, and is primarily for passenger vehicle use; trucks weighing over 10,000 pounds (4,500 kg) are prohibited north of exit 105.

The parkway was constructed between 1946 and 1957 to connect suburban northern New Jersey with the Jersey Shore resort areas along the Atlantic coast and to alleviate traffic on traditional north–south routes running through each town center, such as U.S. Route 1 (US 1), US 9, and Route 35. During planning, the road was to be a toll-free highway designated as the Route 4 Parkway. Most of the highway north of the Raritan River is like any other expressway built in the 1950s through heavily populated areas. Between the Raritan River and the township of Toms River, the highway passes through lighter suburban development, while south of Toms River, the road mostly runs through unspoiled wilderness in the Pine Barrens and swampland. The highway has seen many improvements over the years, including the addition and reconstruction of interchanges, bridge replacements, widening of the roadway, and removal of at-grade intersections. Previously, the road had been maintained by an agency known as the New Jersey Highway Authority (NJHA), however in 2003, the agency merged into the New Jersey Turnpike Authority (NJTA), which now maintains the parkway along with the New Jersey Turnpike.

The parkway uses an open system of toll collection with flat-fee tolls collected at 11 toll plazas along the roadway, as well as at several entrances and exits. Tolls can be paid using cash or via the E-ZPass electronic toll collection system. Along the route are 11 service areas, providing food and fuel to travelers. Historically, the road had ten picnic areas along its length, but only one remains open today.
