Xinghaiwan Bridge, Cross-sea bridge in Dalian, China.

Xinghaiwan Bridge spans across Xinghai Bay to connect different parts of Dalian's urban area. The structure uses steel girders and concrete pillars to cross the water while accommodating multiple traffic lanes.

Construction of the Xinghaiwan Bridge began on 10 October 2011 as part of the Dalian Southern Coastal Road project, and the structure was joined on 5 January 2015 before opening to traffic on 30 October 2015. It was designed by Dalian University of Technology and built by CCCC First and Second Harbor Engineering and China Railway 19th Bureau. In March 2024 its builder, Dalian Southern Coastal Road Investment Co., was fined 27.26 million yuan for lacking sea-area use rights.

The bridge has become a popular sightseeing spot; visitors walk its pedestrian path to view Xinghai Bay and the bridge's alignment with the axis of Xinghai Square. Local media report that this traffic has brought illegal parking and road-safety problems on the bridge.

Access to the bridge is available through multiple connection points with good space for pedestrians and vehicles. Signage is clear and helps visitors navigate, especially during busy traffic times.

The bridge was the first in the world to use a rubble-lifting caisson foundation; each caisson weighed 26,000 tonnes, the heaviest used in China at the time. Its epoxy asphalt pavement is more durable than ordinary asphalt, and a health-monitoring system tracks structural condition.
