The current service between North Greenwich and Abbey Wood has almost 40 stops, but most of these would be missed if the route is turned into a Superloop bus.
Transport for London (TfL) has said that bus stops that are no longer called at would continue to be served by other local routes.
The proposed SL11 bus would follow the same journey as route 472, but with a more direct route down Beresford Street in Woolwich town centre.
Night service N472 would remain unchanged by the proposals, and would continue serving all existing stops between midnight and 5am.
At all other times, passengers might soon be able to catch the new express bus service, that will run seven days a week.
During weekdays and Saturdays, buses would run every eight minutes, or every ten minutes in the evening.
Services would be less frequent on Sundays, with one bus every 12 minutes.
Launching a consultation on the plans today (March 3), TfL said: “The SL11 route aims to create direct journey links between North Greenwich, Woolwich, Thamesmead, and Abbey Wood.
“This would improve journey times and provide quicker outer London connections between Elizabeth line, DLR, London Underground, National Rail and other Superloop services.
“The SL11 would connect with Superloop route SL3 at Abbey Wood and at Thamesmead for onward journeys between Bexleyheath, Sidcup, Bickley, and Bromley.
“We selected bus stop locations with this in mind.”
Despite these benefits, transport bosses have admitted that there will be some “negative impacts” from the proposals.
Some passengers will see a longer overall journey time due to the need to change buses if their stop is no longer called at by the new Superloop service.
Around one in 10 people who currently use route 472 would need to change buses to complete their journeys if the service is withdrawn.
TfL has also said that the proposals for the SL11 would “support” ongoing development in Thamesmead, as well as plans to extend the DLR to the town.
London Mayor Sadiq Khan has said that he wants to double the number of express bus routes across the capital after the “success” of the original 10 routes, which first launched in 2023.
The final route in this first phase of Superloop services will start on April 7, when the opening of the Silvertown tunnel will allow SL4 buses to run between Canary Wharf and Grove Park.
A Superloop bus service that would connect parts of south London earmarked for the Bakerloo line extension has also been proposed.
It is expected that plans for another new route, SL12, which would run between Rainham, Ferry Lane and Gants Hill, will be revealed soon.
The consultation on the SL11 plans runs until April 13.
