Speaking at a Foundation for Science and Technology debate on what will happen to the area after the Games, ODA Chairman John Armitt explained that the ODA is working closely with the London Development Agency (LDA) to create a Park that benefits local communities after 2012.

Armitt also confirmed that good progress is being made to clean and clear a previously neglected and contaminated area to create the largest new urban park in Europe for 150 years.

Work has started on building over 30 new permanent bridges and 20km of roads. Transport links will also be improved to create one of the best-connected areas of the capital.

Two new Energy Centres will be at the heart of a new utilities network being installed in the Park, providing sustainable heating and cooling both during the Games and to local communities after the Games.

Armitt added: "The investment in the regeneration of this area is not coming just from the public sector. London 2012 is also acting as a catalyst for significant private sector investment and last week Westfield announced the green light on the £1.5 billion Stratford City retail-led development adjacent to the Olympic Park."
