Transport for London says that works to repair a collapsed sewer near London Bridge Bus Station - which was due to reopen on Christmas Eve - will now take a further three months to complete.
"Following the recent emergency closure of London Bridge Bus Station by Thames Water for further investigative work into a collapsed sewer, it has emerged that the problem is worse than initially thought and will therefore take significantly longer to repair," said a TfL spokeman on Friday.
"Thames Water requires the bus station to remain closed for a further 12 weeks. During these emergency works London buses will continue to call at nearby stops on London Bridge instead."
Contractors working on The Shard and The Place – as well as Network Rail's station redevelopment project – will take advantage of the closure to carry out work around the bus station earlier than planned.
A temporary taxi rank will be set up on St Thomas Street from Christmas Eve.
