Venues of the 2012 Summer Olympics and Paralympics

The plans were intended to contribute to the regeneration of Stratford in east London which is the site of the Olympic Park and of the neighbouring Lower Lea Valley.

This park was developed on existing waste and industrial land, and is seven minutes by Olympic Javelin train from central London.

Civil engineering companies Morrisons and Nuttalls were appointed to undertake the demolition and land remediation works, under the project management of WS Atkins.

The construction phase of the Olympic Park was managed by CLM, a consortium comprising CH2M Hill, Laing O'Rourke and Mace.

They are quite widely spread across central, west and south London: The men's and women's time trials in road cycling took place on specially laid out courses starting and finishing at Hampton Court Palace.

Both finals (men's and women's) were held at Wembley Stadium: Public transport, an aspect of the bid which scored poorly in the IOC's initial evaluation, has seen numerous improvements, including the expansion of the East London Line, upgrades to the Docklands Light Railway and the North London Line, and the new high-speed Olympic Javelin service.

Windsor Park in Belfast, Northern Ireland, was included as a football venue in the IOC questionnaire submitted in 2004, but excluded in the final candidature file.

The most significant change was the relocation of the volleyball events from a new Olympic Arena to the existing venue of Earls Court, which is several miles to the west.

The revision also involved the re-organisation of the park shuffling the basketball, cycling, fencing, tennis, and field hockey venues in addition to the Press and Broadcast Centre.

The Broxbourne canoe venue was marginally re-sited following the discovery (in October 2007) that the proposed Spitalbrook site was contaminated,[40] while in February 2008 the Weald Country Park was deemed insufficiently challenging for elite mountain biking.
