Hureai Bridge in Japan, image by Flickr user takosaka via Creative Commons

A circular Uruguayan bridge designed by Rafael Viñoly Architects has been receiving a lot of press lately, but it's not the first bridge to take such an approach to river crossing. Pedestrian visitors to Springs Hiyoshi near Kyoto can take a similar leisurely circular route across the Katsura River. The Hureai Bridge (known as the Friendship Bridge in English) was designed by Japanese architect Norihiko Dan and built almost two decades ago in 1998.
