Continuing works by Network Rail in the London Bridge area will mean that London Bridge bus station will be closed to buses and taxis this weekend.
The work, part of the Thameslink Project, means that London Bridge bus station will have to close between 00:01 Saturday 20 August until 05:00 on Monday 22 August.
Buses will call at nearby stops on London Bridge instead. Bus routes affected are numbers 17, 43, 48, 141, 149, N21Â and N343.
Revised stopping arrangements will be clearly displayed on posters around the bus station, in local bus stops and on the Transport for London website.
Passengers are advised to allow extra time to complete their journeys.
Taxis will also be unable to serve the rank at London Bridge bus station but passengers will be able to catch taxis from the ranks on Tooley Street located near the entrance to the London Dungeon attraction.
Taxi marshals will be available to assist with any onward journeys between 08:00 and midnight on Saturday 20 August and 08:30 and midnight on Sunday 21 August.
The works this weekend include lifting into place four steel girders which will form part of a new viaduct above Station Approach.
Continuing resurfacing and paving works on Borough High Street are not affected by these station works with local traffic management remaining in place to ensure smooth traffic flow.
Additional work to transform London Bridge bus station will take place later this year with further details being made available near that time.
When the project is complete it will deliver improvements to the rail station, Underground station and bus station.
Borough Viaduct will double the number of tracks heading north from London Bridge, unlocking extra capacity at London Bridge and reducing delays for passengers coming into London from the South East.
