127-532: 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. The name "ring road"
254-413: 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
381-662: 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 . Edmonton , Alberta, has two ring roads. The first

In December 1978, the Third Plenum of the 11th Party Congress in Beijing under the leadership of Deng Xiaoping reversed the verdicts against victims of
1016-473: A major center of electronics in China. In recent years, the expansion of Beijing has also brought to the forefront some problems of urbanization, such as heavy traffic , poor air quality , the loss of historic neighborhoods, and a significant influx of migrant workers from less-developed rural areas of the country. The city has also been the location of many significant events in recent Chinese history, principally
1143-574: A military frontier command center. During the An-Shi Rebellion and again amidst the turmoil of the late Tang, local military commanders founded their own short-lived Yan dynasties and called the city Yanjing , or the "Yan Capital." Also in the Tang dynasty, the city's name Jicheng was replaced by Youzhou or Yanjing. In 938, after the fall of the Tang, the Later Jin ceded the frontier territory including what

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
2032-426: A total of 600 million people. After this "pollution shock" air pollution became an important economic and social concern in China. After that the government of Beijing announced measures to reduce air pollution, for example by lowering the share of coal from 24% in 2012 to 10% in 2017, while the national government ordered heavily polluting vehicles to be removed from 2015 to 2017 and increased its efforts to transition

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
2286-525: 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 air pollution does directly result in significant impact on the morbidity rate of cardiovascular disease and respiratory disease in Beijing. Exposure to large concentrations of polluted air can cause respiratory and cardiovascular problems, emergency room visits, and even death. Dust from the erosion of deserts in northern and northwestern China results in seasonal dust storms that plague
3429-417: 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

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 ,

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. Most orbital motorways (or beltways) are purpose-built major highways around
