A major redevelopment of Runnymede Roundabout has been approved by Surrey County Council. There is no start time agreed yet but you can find out what the work involves by clicking the link below. The plans for the Glanty Loop and Runnymede Roundabout are at the bottom of the page. All updates will appear on this page as well. This will have a major effect on traffic coming from Old Windsor to Staines/M25/Heathrow whilst the work is being done.
