Dorney Lake
To provide for Olympic spectators, the existing facilities were enhanced to include 20,000 additional seats; most of these seats were temporary. Construction began in October 2009, following investigations by Oxford Archaeology, of enhancements to Dorney Lake, including a new cut-through between the competition lake and the return lane, a new bridge and an upgraded access road, funded by the Olympic Delivery Authority (ODA). During the Olympic events, Dorney Lake was staffed by around 3,500 personnel including volunteers; it could accommodate up to 30,000 spectators per day. A temporary bridge over the River Thames linked the Dorney Lake site to Windsor Racecourse, where a pick-up and drop-off point for Olympic spectators was established. Other access options existed for walkers and cyclists.
