Motorists are being advised to allow extra time for their journeys in and around Canterbury while the controversial Westgate Towers traffic scheme is reverted to its original layout.
Traffic signals were removed over the weekend and the road was resurfaced with new road markings.
The changes were introduced to protect the 14th century towers by reducing the number of vehicles going underneath.
The scheme is being removed following a year long trial. It could be re-introduced permanently after the results are assessed and the community are asked for their views.
