Bus lane in the context of "Bus rapid transit"

Vauxhall Bridge is a Grade II* listed steel and granite deck arch bridge in central London. It crosses the River Thames in a southeast–northwest direction between Vauxhall on the south bank and Pimlico on the north bank. Opened in 1906, it replaced an earlier bridge, originally known as Regent Bridge but later renamed Vauxhall Bridge, built between 1809 and 1816 as part of a scheme for redeveloping the south bank of the Thames. The bridge was built at a location in the river previously served by a ferry.

The building of both iterations of the bridge was problematic, with both the first and second bridges requiring several redesigns from multiple architects. The original bridge, the first iron bridge over the Thames, was built by a private company and operated as a toll bridge before being taken into public ownership in 1879. The second bridge, which took eight years to build, was the first in London to carry trams and later one of the first two roads in London to have a bus lane.

Guided buses are buses capable of being steered by external means, usually on a dedicated track or roll way that excludes other traffic, permitting the maintenance of schedules even during rush hours. Unlike railbuses, trolleybuses or rubber-tyred trams, for part of their routes guided buses are able to share road space with general traffic along conventional roads, or with conventional buses on standard bus lanes. Guidance systems can be physical, such as kerbs or guide bars, or remote, such as optical or radio guidance.

A guided bus line can be categorised as bus rapid transit and may be articulated bus and bi-articulated bus, allowing more passengers, but not as many as light rail or trams, which are not constrained to a regulated maximum size in order to freely navigate public roads.
