To ask the Secretary of State for Environment, Food and Rural Affairs what estimate his Department has made of the proportion of the weight of site material for the construction of the Olympic stadium, associated buildings and infrastructure which has been delivered to the site via Prescott Lock. (275668)

The new lock on Prescott Channel does not formally open until 5 June 2009. Responsibility for traffic to and from the site lies with the Olympic Delivery Authority, which has a publicly stated aspiration of moving 50 per cent. of materials by weight by sustainable means (i.e. rail and river). An award of Freight Facility Grant made to British Waterways by the Department for Transport was based upon 1.01 million tonnes of materials being delivered to the site via Prescott Lock for a minimum period of three years beginning from 31 August 2008.¹
