Increased security as Wimbledon 2017 begins
Protective barriers similar to those installed on Westminster Bridge, London Bridge and other London landmarks have also been placed along the route into Wimbledon. It follows the spate of terror attacks in the capital.
The blockades are a precautionary measure by the Metropolitan Police to ensure the public are safe during the two-week competition.
As part of the policing measures, firearms officers will be deployed around the grounds and plain clothes officers will also be on site.
