The ODA's investment will leave the UK and London with a range of new transport assets, including new trains, platforms, lifts and bigger stations for commuters.
Work that will be finished by 2010 includes includes trebling capacity at Stratford Regional station, a three-car instead of two-car train service on the DLR to boost on-board capacity by 50 per cent on the majority of the network and completion of the new DLR extension to Woolwich Arsenal in February next year.
"The Games will be the catalyst for improved transport links, which are needed to support revitalised communities and future generations in London long after 2012," said ODA Director of Transport Hugh Sumner.
"Stratford Regional Station, for example, currently has 37,000 daily commuters during the morning peak, and we predict that this will rise to 83,000 by 2016. Commuters will benefit from our capacity and accessibility enhancements to the station two years before the Games."
