As part of its investment in sustainable transport, the Olympic Delivery Authority (ODA) has made a significant investment in the waterways in and around the Olympic Park, improving the environment and increasing the functionality to enable the use of the waterways for freight and recreation. This has been assisted by the construction of Three Mills Lock which opened in June 2009.
Between January and December 2009, the volume of freight traffic using the waterways, both into and out of the Olympic Park construction site is as follows:
Barges have transported off the Olympic Park site, 300 tonnes of general waste and timber for recycling, and 1,750 tonnes of residual material from the soil washing plants.
In addition, 600 tonnes of shingle and lightweight aggregate and 460 tonnes of pile cage reinforcement and pipework.
The ODA has an aspiration to transport 50 per cent. of construction material (by weight) by sustainable means to the Olympic Park by rail and water. It is currently achieving 63 per cent.
