A frontage road is a local road running parallel to a higher-speed, limited-access road. A frontage road is often used to provide access to private driveways, shops, houses, industries or farms. Where parallel high-speed roads are provided as part of a major highway, these are also known as local lanes. Sometimes a similar arrangement is used for city roads; for example, the collector portion of Commonwealth Avenue in Boston, Massachusetts, is known as a carriage road.
A dual carriageway (BrE) or a divided highway (AmE) is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation (BrE) or median (AmE). Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc., rather than dual carriageways.
King's Highway 409, commonly referred to as Highway 409 and historically as the Belfield Expressway, is a 400-series highway in the Canadian province of Ontario that extends from Highway 401 in Toronto to Pearson International Airport, west of Highway 427, in Mississauga. It is a short freeway used mainly as a spur route for traffic travelling to the airport or Highway 427 northbound from Highway 401 westbound, as these route movements are not accommodated at the complex interchange between Highways 401 and 427.
The expressways of Singapore are special roads that allow motorists to travel quickly from one urban area to another. Construction of the system was authorized when construction of the Pan Island Expressway began in 1962. All of them are dual carriageways with grade-separated access. They usually have three to four lanes in each direction, although there are two-lane carriageways at many expressway intersections and five-lane carriageways in some places. There are ten expressways. Studies about the feasibility of additional expressways are ongoing.
The Hanlon Expressway or Hanlon Parkway is a high-capacity at-grade suburban limited-access road connecting Highway 401 with the city of Guelph in the Canadian province of Ontario. The 17 km (11 mi) route travels in a generally north-south direction on the city's west side. It is signed as Highway 6 for its entire length; from Wellington Street to Woodlawn Road it is concurrent with Highway 7. The speed limit alternates between 70 and 80 km/h.
The road hierarchy categorizes roads according to their functions and capacities. While sources differ on the exact nomenclature, the basic hierarchy comprises freeways, arterials, collectors, and local roads. Generally, the functional hierarchy can more or less correspond to the hierarchy of roads by their owner or administrator.
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, (draught) 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.
Federal Highways are a series of highways in Mexico. These highways link the nation's 32 federal entities with each other or with a neighboring country, and they are wholly or mostly built by Mexico's federal government with federal funds or through federal grants by individuals, states, or municipalities. Locally known as federal highway corridors, they are built and maintained by Mexico's Secretariat of Communications and Transportation. Federal Highways in Mexico can be classified into high-speed, limited access expressways and low-speed roads with non-limited access; not all corridors are completely improved.
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway and expressway. Other similar terms include throughway and parkway. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic.
The Manila–Cavite Expressway, signed as E3 of the Philippine expressway network and R-1 of Metro Manila's arterial road network, is a 14-kilometer-long (8.7 mi) controlled-access toll expressway linking Manila to the southern province of Cavite in the Philippines. At its north end, it feeds into and from Roxas Boulevard in the city of Parañaque in Metro Manila, also part of R-1. At the south end, it splits into two termini, both along the north coast in Kawit, Cavite. The first feeds into the intersection of Tirona Highway and Antero Soriano Highway. The second southern terminus is on the intersection of Tirona Highway, Antero Soriano Highway and Covelandia Road in Kawit, Cavite.
The Federal Route 2 is a major east–west oriented federal highway in Malaysia. The 276.9 kilometres (172 mi) road connects Port Klang in Selangor to Kuantan Port in Pahang. The Federal Route 2 became the backbone of the road system linking the east and west coasts of Peninsula Malaysia before being surpassed by the East Coast Expressway E8.
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.
A super two, super two-lane highway or wide two-lane is a two-lane surface road built to highway standards with wide lanes and other safety features normally present on a freeway with more lanes, typically including partial control of access, occasional passing lanes and hard shoulders. It is often built for eventual conversion to freeway or at least divided-highway status once traffic volumes rise. Super twos have also been employed because of environmental concerns, such as where Interstate 93 becomes a super two in Franconia Notch, New Hampshire, United States.
Highways in Croatia are the main transport network in Croatia. The Croatian classification includes several classes of highways:
Expressways are the highest class of roads in India. As of July 2023, India has a total length of 4,719 km (2,932 mi) of expressways. These are controlled-access highways where entrance and exits are controlled by the use of cloverleaf or trumpet or grade separated interchanges that are incorporated into the design of the expressway and designed for maximum speed of 120 km/h, whereas National highways are flyover access or controlled-access highway, where entrance and exit is through the side of the flyover, at each intersection of highway with road, flyovers are provided to bypass the city/town/village traffic and these highways are designed for speed of 100 km/h. Some roads are not access-controlled expressways, but are still named as expressways, such as the Biju Expressway, these are actually state highways which are not declared by central government as an Expressway, hence not an Expressway or National Highway. Mumbai–Pune Expressway is the first 6-lane operational expressway in India started in 2002. Expressways follow standards set by Indian Roads Congress and Bureau of Indian Standards.
This article describes the highway systems available in selected countries.
The Malaysian Expressway System is a network of national controlled-access expressways in Malaysia that forms the primary backbone network of Malaysian national highways. The network begins with the Tanjung Malim–Slim River tolled road which was opened to traffic on 16 March 1966, later North–South Expressway (NSE), and is being substantially developed. Malaysian expressways are built by private companies under the supervision of the government highway authority, Malaysian Highway Authority.
Sri Lanka currently has over 271 kilometres (168 mi) of designated expressways serving the southern and central parts of the country. The first stage of the E01 Expressway, which opened in 2011 was Sri Lanka's first expressway spanning a distance of 95.3 kilometres (59.2 mi). The second stage of the Southern Expressway opened in 2014 and extends to Matara. The E03 Expressway opened in 2013 and connects Sri Lanka's largest city Colombo with the Bandaranaike International Airport covering a distance of 25.8 kilometres (16.0 mi). The newest expressway is the Port Access Elevated Highway running from New Kelani Bridge, Colombo to Athurugiriya, It is estimated to be finished in 2025. All E-Grade highways in Sri Lanka are access-controlled, toll roads with speeds limits in the range of 80–110 kilometres per hour (50–68 mph). Pedestrians, bicycles, motorcycles, three wheelers and tractors are not permitted to enter the expressways.
The Philippine expressway network, also known as the High Standard Highway Network, is a controlled-access highway network managed by the Department of Public Works and Highways (DPWH) which consists of all expressways and regional high standard highways in the Philippines.
