Motorists in Bexley spotted symbols of England and Great Britain hanging over the busy road last Friday (August 22).
It was part of a national online movement called ‘Operation Raise the Colours’, which has seen flags put up in other across England, where many have since been removed.
Transport for London (TfL) has since said that unauthorised objects must be removed due to safety.
Since being put up before the Bank Holiday weekend, the flags were taken down.
A TfL spokesperson said: “It is important that infrastructure on our road network remains safe and clear of unauthorised objects.
“Our policy is to remove objects from our infrastructure whenever they are found.”
There have been rows over the motivation of flags being raised across England, as some argue it is just a sign of patriotism, while others fear its intention is to cause more of a divide amid anti-migrant and far-right protests.
A spokesperson for Sir Keir Starmer said he “absolutely” is in favour of people who put up English flags.
The government has also published a guide online saying that flags are “a very British way of expressing joy and pride” and that it wants to “see more flags flown, particularly the Union Flag.”
