THE OLYMPIC Delivery Authority has said it will install a lock on the river Lea in east London as part of its plan to switch transportation of construction materials away from the roads.
The plan will see a water control structure and tidal lock built at Prescott Cut.
The Prescott Channel was built in 1930 as part as flood relief for the River Lea. The channel was named after Major Prescott, a former chairman of the Lea Conservancy.
ODA chief executive David Higgins said: 'We are looking strongly at moving transportation of materials away from road to rail and water.'
The ODA is working with the Environment Agency and British Waterways on the scheme to transport construction waste away from the site.
Mr Higgins confirmed that the ODA has no plans to introduce futuristic security measures such as fingerprint scanning and eye recognition for the army of construction workers required to build the Olympic venues.
He said: 'We don't intend to have biometric testing for workers.'
The ODA will rely on a conventional ID security card system instead.
