London Superloop

Superloop is an express bus network in Greater London, England, that forms part of the London Buses network and connects Outer London town centres, railway stations and transport hubs. Orbital express bus routes were proposed in 2008 by Mayor of London Boris Johnson, with further proposals by the London Assembly in 2017. The 'Superloop' concept was announced in 2023 by Johnson's successor, Sadiq Khan, consisting of renumbering and improvements to existing express bus routes and the introduction of new express bus routes. As of September 2026, seven Superloop routes form a long-distance orbital service around London, with five radial services. The first service became operational on 15 July 2023. All ten of the first phase of routes are operational as of April 2025. Bus stops served by Superloop routes have specific branding to differentiate. Three routes of the second phase are operational, and three more are planned.
