The Emirates Air Line cable car is due to close for a week - sparking a wave of mock panic among Londoners.
The cable car, which critics argue is under-used, will shut for seven days next week in order for maintenance work to be carried out.
A statement on the TfL website said: "The Emirates Air Line will be closed from Monday 7 to Sunday 13 March for essential maintenance work.
"This is to ensure reliability and safety, and to avoid the need for any further closures."
A picture of the TfL notice was posted to Reddit, with the message: "MAJOR ANNOUNCEMENT: EMIRATES CABLE CAR TO BE CLOSED FOR 7 DAYS! HOW WILL WE LIVE?"
And Reddit users have responded in kind, joking that the closure of the line will spell the end for London.
One Reddit user wrote: "ABANDON LONDON! EVERY MAN FOR HIMSELF!"
While another responded with: "Should..... should we eat our children?"
One user questioned: "Who knows what kind of post-apocalyptic hell we will find in the docklands in a week."
Reddit user LadInLondon asked: "How on earth am I able to see East London scrapyards from a height now?"
While another commenter joked: "Both regular users reported to be distraught."
And another simply said simply that they were "devastated".
