The Palisades Interstate Parkway (PIP) is a 38.25-mile-long (61.56 km) limited-access highway in the U.S. states of New Jersey and New York. The parkway is a major commuter route into New York City from Rockland and Orange counties in New York and Bergen County in New Jersey. The southern terminus of the route is at the George Washington Bridge in Fort Lee, New Jersey, where it connects to Interstate 95 (I-95) and U.S. Route 1–9 (US 1–9). Its northern terminus is at a traffic circle in Fort Montgomery, New York, where the PIP meets US 9W and US 202 at the Bear Mountain Bridge. At exit 18, the PIP forms a concurrency with US 6 for the remaining duration of its run.
The route is named for the New Jersey Palisades, a line of cliffs rising along the western side of the Hudson River. The PIP is designated, but not signed as Route 445 in New Jersey and New York State Route 987C (NY 987C), an unsigned reference route, in New York. As with most parkways in the New York metropolitan area, commercial traffic is prohibited from using the PIP. The Palisades Interstate Parkway was built from 1947–1958, and fully opened to traffic on August 28, 1958.
The mainline of the parkway is designated as Route 445 in New Jersey and NY 987C in New York. The latter is one of New York's reference routes. A 0.42-mile (0.68 km) spur connecting the parkway to US 9W in Fort Lee, New Jersey, is designated Route 445S. All three designations are unsigned and used only for inventory purposes. The parkway is owned and maintained by the Palisades Interstate Park Commission but occasional maintenance is performed by the New Jersey and New York state departments of transportation. Commercial vehicles are prohibited on the entire length of the Palisades Interstate Parkway. The speed limit on the highway used to be 50 mph (80 km/h) south of the New York State Thruway and 55 mph (89 km/h) north of it. As of October 2018, it is 55 mph for the entire length.
The Palisades Interstate Parkway begins at the George Washington Bridge (GWB) in Fort Lee, New Jersey. Passengers from the upper level of the GWB can directly get on the PIP northbound, while passengers from the lower level of the bridge must travel through GWB Plaza on US 9W before getting on the parkway. Passengers riding northbound on the New Jersey Turnpike (I-95) must be in local lanes to directly get on the PIP. Once the PIP leaves the GWB, it proceeds north along the New Jersey Palisades, past the Englewood Cliffs Service Area. Unlike service areas further north along the parkway, there are two in Englewood, one for northbound drivers and one for southbound drivers. The others are in the center median shared by drivers going in both directions. There are also three different scenic lookout points over the Palisades near the northern tip of the island of Manhattan at the Harlem River. After this, the PIP parallels US 9W and the Hudson River for its entire run in New Jersey. All four exits in New Jersey are either with US 9W, or within mere feet of the route. The PIP leaves New Jersey into New York in the borough of Rockleigh.
The entire New Jersey portion of the Palisades Interstate Parkway is in Bergen County. It is designated as a state scenic byway known as the Palisades Scenic Byway. The PIP, the New Jersey Turnpike, and Interstate 676 are the only highways that use sequential exit numbering in New Jersey; all others in the state are based on mileage, except for the Atlantic City–Brigantine Connector in Atlantic City, which uses lettered exits (no numerals).
The Palisades enters Rockland County in the hamlet of Palisades. At about the border the PIP changes direction from due north along the Hudson River to a north-west direction. Shortly after the Kings Ferry Service Area in the center median, the first two exits in New York are key exits for two colleges in Rockland County. Exit 5 provides a link to St. Thomas Aquinas College, and exit 6 provides a link to Dominican College. In West Nyack, the PIP has a key interchange with the New York State Thruway (I-87 and I-287). This intersection is about seven miles (11 km) west of the Tappan Zee Bridge. After the PIP's interchange with the NY Thruway, the PIP turns slightly north-east. At exit 13, the PIP intersects US 202 as the route crosses south of Harriman State Park in Mount Ivy. This is the first of two meetings between the PIP and US 202. At exit 15, the PIP has its last busy intersection in Rockland County with County Route 106 (CR 106, formerly part of NY 210) in Stony Point. From here, the PIP enters Harriman State Park, and at exit 16, the PIP intersects Lake Welch Parkway, which is one of several parkways commissioned within the park.
The Palisades enters Orange County north of Lake Welch Parkway at exit 16 and south of the Palisades Interstate Park Commission Visitor Center, located in the center median in what was originally a parkway service area. The first interchange in Orange County is exit 17 at Anthony Wayne Recreation Area. At exit 18, the PIP intersects US 6 and Seven Lakes Drive. US 6 west heads toward the Thruway and NY 17 five miles (8 km) west in Harriman. US 6 east forms the PIP's only concurrency for the last two miles (3 km) of the PIP's run. Seven Lakes Drive joins the two routes for one mile (1.6 km) before departing at exit 19. The two routes then enter Bear Mountain State Park in an eastern direction. Finally, the Palisades Interstate Parkway meets its end at US 9W and US 202 at a traffic circle inches from the Hudson River and the Bear Mountain Bridge. US 6 and US 202 head east over the bridge toward Peekskill, while US 9W north heads toward the United States Military Academy in West Point, and US 9W south and US 202 west form a concurrency south of the circle towards Haverstraw.

In 1933–34, the first thoughts of a Palisades Interstate Parkway were developed by engineer and environmentalist William A. Welch, who was general manager and chief engineer of the Palisades Interstate Park Commission. The plan was to build a parkway to connect the New Jersey Palisades with the state parks along the Hudson River in Rockland and Orange counties. Welch would soon garner the support of John D. Rockefeller, who donated 700 acres (2.8 km2) of land along the New Jersey Palisades overlooking the Hudson River in 1933. With this favorable momentum for the new route, the proposed route was accepted as a Civil Works Administration project under Franklin D. Roosevelt's New Deal coalition. However, the New Jersey Highway Commission did not support construction, so the idea was put on hold.
During the 1940's, Rockefeller renewed the push for a parkway along the New Jersey Palisades, and teamed with ultimate PIP planner, Robert Moses, to establish and design the parkway. The plan originally was to have the PIP stretch from the Garden State Parkway, along the Hudson River, to the George Washington Bridge, and then north along its present-day route ending at the Bear Mountain Bridge. This southern extension was never built, but construction began on the current PIP in New York on April 1, 1947. Construction on the New Jersey portion began about one year later. Construction was delayed twice due to material shortages, but that did not stop the PIP from being opened in stages during the 1940's and 1950's. The route was completed in New Jersey in 1957, and on August 28, 1958, the final piece of the PIP was completed between exits 5 and 9 in southern Rockland County.
The PIP is known for its stone arch overpasses throughout its route and its several scenic overlooks in New Jersey. All sorts of unique trees and flowers can be seen along the route as well. In 1998, because of all the natural and constructed beauty, the PIP was designated as a national landmark by the National Park Service.
