Three Mills Lock

Prescott Channel, London, UK


Three Mills Lock, London’s first new lock for 20 years, was officially opened by British Waterways’ Chairman, Tony Hales and Olympic Delivery Authority Chairman, John Armitt.

British Waterways awarded the £20m Design & Build contract for the new tidal lock, fixed and adjustable weirs and fish pass to main contractor VolkerStevin with Tony Gee as lead designer.

The new lock opens up the Bow Back Rivers, a network of waterways in and around the Lower Lea Valley. This creates a green gateway for freight barges and revives water transport in the area for the first time in 50 years.

The project comprises twin water control gates, a 62 m x 8 m tidal lock, lock control building, fish pass and fixed and adjustable weirs. The lock controls the rivers upstream at a navigable depth, excludes tidal influx and regulates fluvial flood events. The scheme also included a 41 m long two-span footbridge which provides public access along the lock complex.

Three Mills Lock and the associated water control structures have been funded by British Waterways, the Department for Transport, London Thames Gateway Development Corporation, the Department for Environment, Food and Rural Affairs, the Olympic Delivery Authority, London Development Agency and Transport for London, with design and build delivered by contractor VolkerStevin.
