In this Sunday, Feb. 23, 2014 photo, people take a look at the construction site in Queen Elizabeth Olympic Park in east London. The Games' Velodrome is seen left. London continues to bask in the success of the most recent Summer Games, but the Olympic legacy is difficult to determine. The flagship venue, renamed the Queen Elizabeth Olympic Park, is being converted into a massive park as big as London’s famous Hyde Park, complete with wildlife habitats, woods and sports facilities. The first part of the ambitious project will begin to open to the public in April. The 80,000-seat Olympic Stadium at the center of the park has been troubled by controversy since even before the games, and its post-games use was the subject of months of legal wrangling. The stadium is now being converted into a soccer venue and the home of the West Ham soccer club, with an expected price tag of $323 million. Many argue taxpayers should not have to fund a Premier League club, though officials insist that the stadium will continue to host other major sporting events, including the Rugby World Cup in 2015.
