Portsmouth Road will be closed from Esher through Surbiton to Kingston Bridge.

Closures will be from early morning on Saturday 9 and Sunday 10 August to make sure the routes are secure and ready for the event.

There will be extensive road and river crossing closures throughout the day; roads will be closed from 05:00 and will re-open in phases once the event has passed and it is safe to do so. Pedestrian access to properties will not be affected. All London roads are expected to be reopened by 20:30. The affected river crossings will be closed for most of the day; these are Blackwall Tunnel and Tower, Southwark, Westminster, Lambeth, Vauxhall, Battersea, Chelsea, Albert, Chiswick, Putney, Kingston and Hampton Court bridges.
