The leak was serious enough to require immediate attention so work began at 8am on Saturday – Thames Water and their contractors have repaired the leak and will now be repairing the road surface and pavement.
Initial estimates were that this all might take two days and a temporary traffic-light signal system will restrict traffic whilst this takes place.
Combined with the gas works on Park road and traffic heading for the rugby final at Twickenham (Harlequins are now premiership champions for the first time ever!), long tail-backs blighted the area throughout Saturday. Thames Water ref 10469 if you wish to find out more info.
