The Mayor of London has unveiled plans for a major expansion of outer London's bus network.

The Superloop would be made up of limited-stop express bus routes around outer London – including Bexley and Bromley.

Today, Sadiq Khan announced plans for a network of limited-stop express bus routes that circle the entire capital – connecting outer London town centres, railway stations, hospitals and transport hubs, faster.

He claims the Superloop will make journey times quicker, and is providing £6m funding as an initial catalyst to improvements to outer London orbital bus services.

It is proposed to be introduced in stages, and will comprise 10 routes in total – four of these are existing.

Existing routes are the X26, which runs from Croydon to Heathrow Airport, the X140 which runs from Heathrow Airport to Harrow, the 607 which runs from Uxbridge to White City and the X68 which runs from Russell Square to Croydon.

The next new part of the outer London bus network will be the route linking Harrow with North Finchley, subject to consultation.

Following that, views will be sought on future sections of the orbital network.

Links are proposed between Bexleyheath, Sidcup, Queen Mary's Hospital and Bromley.

Some of the benefits of the proposed Superloop will be released later this year.

The Superloop brand is designed to work with the London Buses brand, by using a new Roundel and bus livery to ensure clear identification of the new service.

The new branding will also feature on maps, timetables and other pieces of customer information.

The Superloop will be designed to provide quicker journey times while still serving key hubs and interchanges with rail and local bus services.

TfL confirmed yesterday that more than £35m of further funding has been allocated to outer London boroughs to make streets healthier and safer for all as part of its Local Implementation Plan funding.

The programme will see 29km of bus lane schemes and is providing £10.6m to London boroughs to deliver bus journey time improvements.

Enhanced public transport, walking and cycling options in outer London is being encouraged to help people move to more sustainable travel options.

Sadiq Khan, said: "When I made the tough decision to expand the ULEZ London-wide, one of my key commitments to Londoners was to improve transport links in outer London.

"Today I am delivering on that commitment as we announce the Superloop, the game-changing new network of express buses that will add over four million additional kilometres to our bus network in outer London, linking stations, town centres, hospitals and transport hubs.

"These new routes will make it much easier for Londoners to get around the capital, and help build a better, greener London for everyone."

"Part of making the bus network even more attractive is providing new routes and increasing frequencies where it is required – both of which we are doing with this new iconic service..."

Alex Williams, chief customer and strategy officer at TfL, said: "The Superloop is the jewel in the crown in our plans to strengthen alternatives to the private car ahead of the ULEZ expanding London-wide and is a game changer for outer London.

"For the first time we will be bringing a number of the capital’s town centres together with express orbital routes.

"We know these kinds of services are hugely popular from what we have seen in the rise in the number of people using the X140 during the week.

“Part of making the bus network even more attractive is providing new routes and increasing frequencies where it is required – both of which we are doing with this new iconic service.

"The Superloop is on top of, and complements, a million additional bus kilometres committed by the Mayor in the capital’s outer ring and includes improvements from Sutton in the south to Brent Cross in the north, as well as transformational changes to London’s rail network outside the centre of the city."
