If there are no strong land use controls, buildings are often built in town along a bypass, converting it into an ordinary town road, and the bypass may eventually become as congested as the local streets it was intended to avoid.
Bypass routes are often controversial, as they require the building of a road carrying heavy traffic where no road previously existed. This creates a conflict between those who support a bypass to reduce congestion in a built up area, and those who oppose the development of (often rural) undeveloped land. However, some of those in the bypassed city may also oppose the project, because of the potential reduction in city-centre business.

The idea of bypasses predates the use of motor vehicles. The first (northern) London bypass, the present Marylebone Road between Paddington and Islington, was started in 1756.
Bypasses can take many years to gain planning approval and funding. Many towns and villages have been campaigning for bypasses for over 30 years e.g. Banwell in North Somerset.[2]
There was large-scale protest during construction of the Newbury bypass—officially known as the Winchester–Preston Trunk Road (A34) (Newbury Bypass)—a 9-mile (14 km) stretch of dual carriageway which bypasses the town of Newbury in Berkshire, England. The protest was popularly known as the Third Battle of Newbury, a name which was also adopted by one of the main protest groups. The name was chosen in reference to the First Battle of Newbury of 1643 and the Second Battle of Newbury of 1644, both of which took place close to the town during the English Civil War.
United States
In the United States, bypass routes are a type of special route used on an alternative routing of a highway around a town when the main route of the highway goes through the town. The original designation of these routes were "truck routes" to divert through truck traffic away from the town, but the designation was changed to "bypass" in 1959 by AASHTO.[citation needed] However, many "truck" routes remain where the mainline of the highway is prohibited for trucks.
In a few cases, both a bypass and a

Another meaning of the term bypass route (usually simply called a bypass) is a highway that was constructed to bypass an area that is often congested with traffic. This includes Interstate Highway
The first bypass route in the United States was completed in 1958 as Alabama State Route 210 (Ross Clark Circle) in Dothan, Alabama.[citation needed]
Shoofly
In the United States, the term shoofly – a borrowing from railroad jargon – is also sometimes used to refer to a short temporary roadway built to bypass a construction site or other temporary obstruction.[3] The U.S. Manual on Uniform Traffic Control Devices uses the term "diversion".[4]
Brazil
In Brazil the widest and busiest bypasses are located in the state of São Paulo, and many of them intersect and merge around large cities to form ring-like systems. Most notably the Rodoanel Mário Covas, which encircles the city of São Paulo and passes through other cities in the metropolitan area, is the largest project of such type with a planned total length of 180 km upon completion. It is divided into sections and connected to major highways and while not being a toll road itself, accesses to other motorways are often placed through toll booths.

Malaysia
Malaysia also contain several bypasses such as Rawang Bypass, Kajang Bypass, Bidor Bypass and Kuala Terengganu Bypass.
Philippines
Bypass roads (or in other cases "diversion roads") in the Philippines are generally considered on national highways passing through a densely populated city or municipality. Local governments usually promote construction of bypasses where the existing highway becomes heavily congested. Bypasses are common in rural municipalities to deter through traffic from entering the poblacion or town centre. Careful planning is considered when planning a bypass through a community to ensure the original route is downgraded to local access. Control of access to properties is taken in account to avoid uncontrolled land development.
