The Trans-Canada Highway is a transcontinental federal–provincial highway system that travels through all ten provinces of Canada, from the Pacific Ocean on the west coast to the Atlantic Ocean on the east coast. The main route spans 7,476 km (4,645 mi) across the country, one of the longest routes of its type in the world. The highway system is recognizable by its distinctive white-on-green maple leaf route markers, although there are small variations in the markers in some provinces.
Route 29 is a state highway in the U.S. state of New Jersey. Signed north-south, it runs 34.76 mi (55.94 km) from an interchange with Interstate 295 (I-295) in Hamilton Township in Mercer County, where the road continues east as I-195, northwest to Route 12 in Frenchtown, Hunterdon County. Between the southern terminus and I-295 in Ewing Township, the route is a mix of expressway and boulevard that runs along the Delaware River through Trenton. This section includes a truck-restricted tunnel that was built along the river near historic houses and Riverview Cemetery. North of I-295, Route 29 turns into a scenic and mostly two-lane highway. North of the South Trenton Tunnel, it is designated the Delaware River Scenic Byway, a New Jersey Scenic Byway and National Scenic Byway, that follows the Delaware River in mostly rural sections of Mercer County and Hunterdon County. The obsolete Delaware & Raritan Canal usually stands between the river and the highway. Most sections of this portion of Route 29 are completely shaded due to the tree canopy. Route 29 also has a spur, Route 129, which connects Route 29 to U.S. Route 1 (US 1) in Trenton.
King's Highway 401, commonly referred to as Highway 401 and also known by its official name as the Macdonald–Cartier Freeway or colloquially referred to as the four-oh-one, is a controlled-access 400-series highway in the Canadian province of Ontario. It stretches 828 kilometres (514 mi) from Windsor in the west to the Ontario–Quebec border in the east. The part of Highway 401 that passes through Toronto is North America's busiest highway, and one of the widest. Together with Quebec Autoroute 20, it forms the road transportation backbone of the Quebec City–Windsor Corridor, along which over half of Canada's population resides. It is also a Core Route in the National Highway System of Canada. The route is maintained by the Ministry of Transportation of Ontario (MTO) and patrolled by the Ontario Provincial Police. The speed limit is 100 km/h (62 mph) throughout the majority of its length, with the remaining exceptions being the posted 80 km/h (50 mph) limit westbound in Windsor, in most construction zones, and the 110 km/h (68 mph) speed limit on the 40 km (25 mi) stretch between Windsor and Tilbury that was raised on April 22, 2022, the 7 km (4.3 mi) extension east of the aforementioned, the 35 km (22 mi) stretch between Highway 35 / 115 and Cobourg, the 44 km (27 mi) stretch between Colborne and Belleville, the 66 km (41 mi) stretch between Belleville and Kingston, and the 107 km (66 mi) stretch between Highway 16 and the east end of the highway that were raised on July 12, 2024.
A National Parkway is a designation for a protected area in the United States given to scenic roadways with a protected corridor of surrounding parkland. National Parkways often connect cultural or historic sites. The U.S. National Park Service manages the parkways.
The Arroyo Seco Parkway, also known as the Pasadena Freeway, is one of the oldest freeways in the United States. It connects Los Angeles with Pasadena alongside the Arroyo Seco seasonal river. Mostly opened in 1940, it represents the transitional phase between early parkways and later freeways. It conformed to modern standards when it was built, but is now regarded as a narrow, outdated roadway. A 1953 extension brought the south end to the Four Level Interchange in downtown Los Angeles and a connection with the rest of the freeway system.
King's Highway 7, commonly referred to as Highway 7 and historically as the Northern Highway, is a provincially maintained highway in the Canadian province of Ontario. At its peak, Highway 7 measured 716 km (445 mi) in length, stretching from Highway 40 east of Sarnia in Southwestern Ontario to Highway 17 west of Ottawa in Eastern Ontario. However, due in part to the construction of Highways 402 and 407, the province transferred the sections of Highway 7 west of London and through the Greater Toronto Area to county and regional jurisdiction. The highway is now 535.7 km (332.9 mi) long; the western segment begins at Highway 4 north of London and extends 154.1 km (95.8 mi) to Georgetown, while the eastern segment begins at Donald Cousens Parkway in Markham and extends 381.6 km (237.1 mi) to Highway 417 in Ottawa.
King's Highway 417, commonly referred to as Highway 417 and as the Queensway through Ottawa, is a 400-series highway in the Canadian province of Ontario. It connects Ottawa with Montreal via A-40, and is the backbone of the highway system in the National Capital Region. Within Ottawa, it forms part of the Queensway west from Highway 7 to Ottawa Road 174. Highway 417 extends from the Quebec border, near Hawkesbury, to Arnprior, where it continues westward as Highway 17. Aside from the urban section through Ottawa, Highway 417 passes through farmland that dominates much of the fertile Ottawa Valley.
A limited-access road, known by various terms worldwide, including limited-access highway, dual-carriageway, expressway, and partial controlled-access highway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a controlled-access highway, including limited or no access to adjacent property, some degree of separation of opposing traffic flow, use of grade separated interchanges to some extent, prohibition of slow modes of transport, such as bicycles, horse-drawn vehicles or ridden horses, or self-propelled agricultural machines; and very few or no intersecting cross-streets or level crossings. The degree of isolation from local traffic allowed varies between countries and regions. The precise definition of these terms varies by jurisdiction.

The eastern segment runs from the southeasterly part of Death Valley to Nevada State Route 372 at the Nevada state line.
The Niagara Scenic Parkway is a 16.4-mile (26.39 km) state parkway in western Niagara County, New York, in the United States. Its southern terminus is at the LaSalle Expressway on the east bank of the Niagara River in Niagara Falls. The northern terminus is at New York State Route 18 (NY 18) at Four Mile Creek State Park in Porter near Lake Ontario. Originally, the parkway was one continuous road; however, due to low usage, a portion of the parkway near Niagara Falls was removed, separating the parkway into two sections. The length of the parkway is designated as New York State Route 957A by the New York State Department of Transportation (NYSDOT). A 1.16-mile (1.87 km) long spur connecting the Niagara Scenic Parkway to Fort Niagara State Park near Youngstown is designated as New York State Route 958A.

The Thousand Islands Parkway (often written as 1000 Islands Parkway) is a scenic parkway in the Canadian province of Ontario. It extends easterly from an interchange with Highway 401 in Gananoque for approximately 40 kilometres (25 mi) to rejoin Highway 401 near the community of Butternut Bay, west of Brockville. The parkway follows the north shore of the St. Lawrence River, and was formerly designated Highway 2S (S for Scenic) until 1970. It passes through the communities of Gray's Beach, Halsteads Bay, Ivy Lea, Darlingside, Rockport, Narrows, La Rue Mills and Mallorytown Landing, as well as providing access to the three inland properties of the Thousand Islands National Park.

A two-lane expressway or two-lane freeway is an expressway or freeway with only one lane in each direction, and usually no median barrier. It may be built that way because of constraints, or may be intended for expansion once traffic volumes rise. The term super two is often used by roadgeeks for this type of road, but traffic engineers use that term for a high-quality surface road. Most of these roads are not tolled.
The majority of parkways in the US state of New York are part of a statewide parkway system owned by several public and private agencies but mostly maintained by the New York State Department of Transportation (NYSDOT). A handful of other roads in the Hudson Valley and on Long Island are also known as parkways but are not part of the state system. The roads of the state parkway system were among the first expressways to be constructed. These highways were not divided and allowed no driveway cuts, but did have intersections for some of the streets they crossed. A small section of the privately financed Long Island Motor Parkway was the first expressway to begin operation as a toll road and the first highway to use bridges and overpasses to eliminate intersections.
U.S. Route 202 is a US Highway running from New Castle, Delaware, northeast to Bangor, Maine. In the U.S. state of Pennsylvania, the route runs for 59 miles (95 km), from the Delaware state line in Bethel Township, Delaware County, to the New Hope–Lambertville Toll Bridge over the Delaware River in Solebury Township, where the route crosses into New Jersey. The highway runs through the western and northern suburbs of Philadelphia in the Delaware Valley metropolitan area, and serves as a toll-free bypass around the city, avoiding the busy traffic and congestion on Interstate 95 (I-95). It is signed north–south and follows a general southwest–northeast direction through the state.
Park Drive is a mostly one-way, two-lane parkway in the Fenway-Kenmore neighborhood of Boston that runs along the northern and western edges of the Back Bay Fens before ending at Mountfort Street.
