Chongming–Qidong Yangtze River Bridge, Box girder bridge in Shanghai, China.

The Chongming–Qidong Yangtze River Bridge, also called the Chongqi Bridge, is a box girder bridge carrying the six-lane G40 Shanghai–Xi'an Expressway across the north fork of the Yangtze River, from Chenjia on Chongming Island in Shanghai to Qidong in Jiangsu Province. Its longest span measures 185 metres, and the crossing includes 6.84 km over the water.

The bridge was built from 2008 to 2011 at a cost of RMB 8.238 billion. Work began with the foundation stone on 1 August 2008, and the structure opened to traffic on 24 December 2011. It carries the six-lane G40 Shanghai–Xi'an Expressway across the north fork of the Yangtze, forming the river's last crossing before the East China Sea.

The name Chongqi combines Chongming and Qidong, the two places it joins. Drivers cross the north fork of the Yangtze on the G40 expressway, the last river crossing before the water reaches the East China Sea. The bridge is the northern half of the Chongqi Crossing Project, paired with the Shanghai Yangtze Tunnel and Bridge.

The bridge provides a direct connection on the G40 route and significantly reduces travel times between Shanghai and Jiangsu. Visitors should expect heavy traffic during peak hours and quieter conditions during late nighttime.

As of December 2011 the Chongqi Bridge was the longest box girder bridge in China, with a longest span of 185 metres. Its 51.763 km of viaduct include 6.84 km across the north fork of the Yangtze, and the whole project cost RMB 8.238 billion.
