The first Olympic project, two tunnels running under the Olympic Park, have been completed on time and budget.

2012 Olympic Park before construction

The ODA announced today that the tunnels, which will carry the power needed for the Games and legacy, have been successfully completed.

The work started in April 2006 to create the two 6km tunnels to provide power for the games and for the community post-2012.

The construction of the tunnels will allow 52 pylons to be removed, freeing up the Olympic Park site for construction of the main venues and infrastructure.

ODA Chairman David Higgins said: “Burying the powerlines underground is essential in unlocking the Olympic Park site for the start of construction next year and is a vital part of the long term regeneration of east London."

“The successful completion of this massive tunnelling project on time and on budget gives us real momentum as we set our sites on the challenge ahead. “
