A ring road (also known as circular road, beltline, beltway, circumferential (high)way, loop or orbital) is a road or a series of connected roads encircling a town, city or country. The most common purpose of a ring road is to assist in reducing traffic volumes in the urban centre, such as by offering an alternate route around the city for drivers who do not need to stop in the city core. Ring roads can also serve to connect suburbs to each other, allowing efficient travel between them.

Nomenclature

The Third Ring Road in the area of the Moscow International Business Center.

The name "ring road" is used for the majority of metropolitan circumferential routes in Europe, such as the Berliner Ring, the Brussels Ring, the Amsterdam Ring, the Boulevard Périphérique around Paris and the Leeds Inner and Outer ring roads. Australia, Pakistan and India also use the term ring road, as in Melbourne's Western Ring Road, Lahore's Lahore Ring Road and Hyderabad's Outer Ring Road. In Canada the term is the most commonly used, with "orbital" also used, but to a much lesser extent.

In Europe and Australia, some ring roads, particularly longer ones of motorway standard, are known as "orbital motorways". Examples are the London Orbital (generally known as the M25; 188 km), Sydney Orbital Network (110 km) and Rome Orbital (68 km).

In the United States many ring roads are called beltlines, beltways or loops, such as the Capital Beltway around Washington, D.C. Some ring roads, such as Washington's Capital Beltway, use "Inner Loop" and "Outer Loop" terminology for directions of travel, since cardinal (compass) directions cannot be signed uniformly around the entire loop. The term 'ring road' is occasionally – and inaccurately – used interchangeably with the term 'bypass'.

Background

The Sydney Orbital Network, New South Wales, Australia

Bypasses around many large and small towns were built in many areas when many old roads were converted to four-lane status in the 1930s to 1950s, such as those along the Old National Road (now generally U.S. 40 or Interstate 70) in the United States, leaving the old road in place to serve the town or city, but allowing through travelers to continue on a wider, faster and safer route.

Construction of fully circumferential ring roads has generally occurred more recently, beginning in the 1960s in many areas, when the U.S. Interstate Highway System and similar-quality roads elsewhere were designed. Ring roads have now been built around numerous cities and metropolitan areas, including cities with multiple ring roads, irregularly shaped ring roads and ring roads made up of various other long-distance roads.

London has three ring roads (the M25 motorway, the North and South Circular roads and the Inner Ring Road). Birmingham also has three ring roads which consist of the Birmingham Box; the A4540, commonly known as the Middleway; and the A4040, the Outer Ring Road. Birmingham once had a fourth ring road, the A4400. This has been partially demolished and downgraded to improve traffic flow into the city. Other British cities have two: Leeds, Sheffield, Norwich and Glasgow. Cleveland, OH and San Antonio, TX, in the United States, also each have two, while Houston, Texas will have three official ring roads (not including the downtown freeway loop). Some cities have far more – Beijing, for example, has six ring roads, simply numbered in increasing order from the city center (though skipping #1), while Moscow has five, three innermost (Central Squares of Moscow, Boulevard Ring and Garden Ring) corresponding to the concentric lines of fortifications around the ancient city, and the two outermost (MKAD and Third Ring) built in the twentieth century, though, confusingly, the Third Ring was built last.

Geographical constraints can complicate the construction of a complete ring road. For example, the Baltimore Beltway in Maryland crosses Baltimore Harbor on a high arch bridge, and much of the partially completed Stockholm Ring Road in Sweden runs through tunnels or over long bridges. Some towns or cities on sea coasts or near rugged mountains cannot have a full ring road. Examples of such partial ring roads are Dublin's ring road; and, in the USA, Interstate 287, mostly in New Jersey (bypassing New York City), and Interstate 495 around Boston, none of which completely circles these seaport cities.

In other cases, adjacent international boundaries may prevent ring road completion. Construction of a true ring road around Detroit is effectively blocked by its location on the border with Canada and the Detroit River; although constructing a route mostly or entirely outside city limits is technically feasible, a true ring around Detroit would necessarily pass through Canada, and so Interstate 275 and Interstate 696 together bypass but do not encircle the city. Sometimes, the presence of significant natural or historical areas limits route options, as for the long-proposed Outer Beltway around Washington, D.C., where options for a new western Potomac River crossing are limited by a nearly continuous corridor of heavily visited scenic, natural, and historical landscapes in the Potomac River Gorge and adjacent areas.

When referring to a road encircling a capital city, the term "beltway" can also have a political connotation, as in the American term "Inside the Beltway", derived metonymically from the Capital Beltway encircling Washington, D.C.

Impact

Ring roads have been criticised for inducing demand, leading to more car journeys being taken and thus higher levels of pollution being created. By creating easy access by car to large areas of land, they can also act as a catalyst for development, leading to urban sprawl and car-centric planning. Ring roads have also been criticised for splitting communities and being difficult to navigate for pedestrians and cyclists.

The Leeds Inner Ring Road in England was built in a series of tunnels to save space and avoid physically separating the city's centre from its suburbs.

Sardar Patel Ring Road, Ahmedabad

Most orbital motorways (or beltways) are purpose-built major highways around a town or city, typically without either signals or road or railroad crossings. In the United States, beltways are commonly parts of the Interstate Highway System. Similar roads in the United Kingdom are often called "orbital motorways". Although the terms "ring road" and "orbital motorway" are sometimes used interchangeably, "ring road" often indicates a circumferential route formed from one or more existing roads within a city or town, with the standard of road being anything from an ordinary city street up to motorway level. An excellent example of this is London's North Circular/South Circular ring roads, which are largely made up of (mainly congested) ordinary city streets.

In some cases, a circumferential route is formed by the combination of a major through highway and a similar-quality loop route that extends out from the parent road, later reconnecting with the same highway. Such loops not only function as a bypass for through traffic, but also to serve outlying suburbs. In the United States, an Interstate highway loop is usually designated by a three-digit number beginning with an even digit before the two-digit number of its parent interstate. Interstate spurs, on the other hand, generally have three-digit numbers beginning with an odd digit.

Circumferential highways are prominent features in or near many large cities in the United States. In many cases, such as Interstate 285 in Atlanta, Georgia, circumferential highways serve as a bypass while other highways pass directly through the city center. In other cases, a primary Interstate highway passes around a city on one side, with a connecting loop Interstate bypassing the city on the other side, together forming a circumferential route, as with I-93 and I-495 in the area of Lawrence, Massachusetts. However, if a primary Interstate passes through a city and a loop bypasses it on only one side (as in the Wilmington, Delaware, area), no fully circumferential route is provided. Within cities, ring roads sometimes have local nicknames; these include Washington DC's Interstate 495 (The "Capital Beltway"), Interstate 270 in Columbus, Ohio (The "Outerbelt"), and Interstate 285 in Atlanta (The "Perimeter").

Route numbering is challenging when a through highway and a loop bypass together form a circumferential ring road. Since neither of the highways involved is circumferential itself, either dual signage or two (or more) route numbers is needed. The history of signage on the Capital Beltway around Washington, D.C., is instructive here. Interstate 95, a major through highway along the U.S. East Coast, was originally planned as a through-the-city route there, with the Beltway encircling the city as I-495. The portion of I-95 entering the city from the south was soon completed (and so signed), primarily by adapting an existing major highway, but the planned extension of I-95 through residential areas northward to the Beltway was long delayed, and eventually abandoned, leaving the eastern portion of the Beltway as the best Interstate-quality route for through traffic.

This eastern portion of the Beltway was then redesignated from I-495 to I-95, leaving the I-495 designation only on the western portion, and the completed part of the planned Interstate inside the Beltway was redesignated as a spur, I-395. A few years later, the resulting confusion from different route numbers on the circumferential Beltway was resolved by restoring I-495 signage for the entire Beltway, with dual signage for I-95 for the highway's concurrent use as a through Interstate on its eastern portion.

The longest complete beltway in the United States is the Charles W. Anderson Loop, a 94-mile (151 km) loop in Texas that forms a complete loop around the Greater San Antonio area.

The longest complete belt road, or a beltway that is only two lanes, in the United States is Hawaii Belt Road, a 260-mile (420 km) belt in Hawaii that forms a complete belt road around Hawaii Island.

Other major U.S. cities with such a beltway superhighway:

There are other U.S. superhighway beltway systems that consist of multiple routes that require multiple interchanges and thus do not provide true ring routes. Two designated examples are the Capital Beltway around Harrisburg, Pennsylvania using Interstate 81, Interstate 83, and Pennsylvania Route 581 and “The Bypass” around South Bend, Indiana using Interstate 80, Interstate 90, U.S. Route 31, and Indiana State Road 331.

Canada

Stoney Trail is a ring road that circles the city of Calgary, Alberta, for an entire length of 101-kilometre (63 mi).

Winnipeg, Manitoba, has a ring road which is called the Perimeter Highway. It is designated as Manitoba Highway 101 on the north, northwest and east sides and as Manitoba Highway 100 on the south and southwest sides. The majority of it is a four-lane divided expressway. It has a second ring road, planned since the 1950s and not yet completed, called the Suburban Beltway. It consists of several roads—Lagimodière Boulevard, Abinojii Mikanah, the Fort Garry Bridge, the Moray Bridge, William R Clement Parkway, Chief Peguis Trail and the Kildonan Bridge.

Saskatoon, Saskatchewan, has a ring road named Circle Drive. It is cosigned as Saskatchewan Highway 16 and Saskatchewan Highway 11 along the whole route since the 2013 opening of Circle Drive South.

Regina, Saskatchewan has a partial ring road that is named Ring Road; however, due to the city's urban growth since the road was originally constructed, it no longer functions as a true ring road and has instead come to be used partially for local arterial traffic. The Regina Bypass, a new partial ring road, has replaced it.

Hamilton, Ontario, has the Lincoln M. Alexander Parkway, Highway 403 and the Red Hill Valley Parkway which form a ring on three sides.

Sudbury, Ontario, has a partial ring road consisting of the Southwest and Southeast Bypasses segment of Highway 17, and the Northwest Bypass segment of Highway 144.

Europe

Grande Raccordo Anulare, the ring road of Rome, Italy

Most major cities in Europe are served by a ring road that circles either the inner core of their metropolitan areas or the outer borders of the city proper or both. In major transit hubs, such as the Île-de-France region surrounding Paris and the Frankfurt area, major national highways converge just outside city limits before forming one of several routes of an urban network of roads circling the city. Unlike in United States, route numbering is not a challenge on European ring roads as routes merge to form the single designated road. However, exit and road junction access can be challenging due to the complexity of other routes branching from or into the ring road.

One of the most renowned ring roads is the Vienna Ring Road (Ringstraße), a grand boulevard constructed in the mid-19th century and filled with representative buildings. Due to its unique architectural beauty and history, it has also been called the "Lord of the ring roads", and is declared by UNESCO as part of Vienna's World Heritage Site.
