The Dongshuimen Bridge (pinyin: Dōngshuǐmén dàqiáo) and the Qiansimen Bridge (pinyin: Qiānsīmén dàqiáo), known collectively as the Twin River Bridges, are a pair of bridges that form a road and rail connection in Chongqing, China. Consisting of two cable-stayed bridges and a tunnel across the Yuzhong peninsula where the heart of Chongqing's commercial & financial district Jiefangbei CBD is located, the connection opened in 2014.
