An elevated walkway in the Lujiazui district of Shanghai, China

This circular walkway elevates pedestrians off the busy streets of the Lujiazui district in Shanghai. Located on a peninsula framed by the Huangpu River, Lujiazui has become the city’s major business center, with global corporations building or occupying many of the district’s skyscrapers. This photo was taken from the Shanghai Tower, currently the second-tallest building in the world.
