Prescott Lock

The new Prescott Lock will control the river above Three Mills at a navigable, but flowing, depth and 'lock-out' the tide. It will create a green gateway for barges entering the Olympic Park, helping to remove up to 1,000 lorry journeys a week from local roads.

Water transport is greener, cleaner and more sustainable than road haulage, using less than a third of fuel and emitting less than a sixth of the pollution. The new lock will help to improve local air quality, saving 4,000 tonnes of carbon dioxide in the build up to the Olympics alone and creating a green transport network for future movement of waste and recyclables by barge.

The lock will be 62m long and 8m wide, and will include sluice gates, a public footbridge, 'fish pass' and a twin sluice on Three Mills Wall River.
