ODA director of infrastructure and utilities Simon Wright said: "Lifting the first permanent new bridge into place and awarding the last major bridge construction contract are significant moments and keep us firmly on track as we create the backbone of the Olympic Park and a platform for future development.
"Building new bridges and roads is a crucial element across the life of the project, from creating new links across the site for construction activity, to delivering an open and accessible Park during the Games, and forming new links between local communities in legacy," he said.
A 250t crane was used to lift three 55m-long steel beams into place to form the main deck of the bridge.
The bridge is in the north of the Olympic Park, spanning across the River Lea to form an east–west link across the site.
The bridge will initially be used by site vehicles during the construction phase of the project, and then during the Games and in legacy it will form part of the main loop road around the Olympic Park to provide an essential link around the site for pedestrians and vehicles.
The final major bridge contract has now been awarded to Lagan Construction to construct a major footbridge in the centre of the Olympic Park, spanning approximately 30m over the River Lea between the Olympic Stadium and Aquatics Centre.
It has been designed by Heneghan Peng Architects, with Adams Kara Taylor Engineers, and features a single bridge structure with temporary elements in Games time that is transformed in legacy to leave two footbridges linked by a central blade-like walkway, linking the river tow paths and the upper concourse in the Olympic Park. Construction work will start next year.
