Chongqing overpasses an impressive sight from the air

Chongqing is a mountainous city in Southwest China, with many overpasses built to ease traffic pressure. It's estimated that there were 215 overpasses in the city by the end of 2016. This year marks the 20th anniversary since it became the fourth municipality after Beijing, Tianjin and Shanghai. To celebrate the anniversary, a group of photographers spent six months capturing the magic of the overpasses at night. [Photo/VCG]
