Longmen Second Bridge is a parallel 2-lane concrete filled steel tubular CFST arch that will work with the Xinlongmens arch bridge from 2010 to make a 4-lane crossing to handle increased traffic from a new development on the east side of the Daning River in Wushan City, Chongqing. The Longmen Second Bridge is located 51 meters downstream of the Xinlongmens steel arch bridge. The arch has a rise of 62 meters and a width of 16 meters with 3 meters of bicycle, 3 meters of sidewalks and 1 meter of maintenance walkway.

The Longmen "Dragon Gate" Second Bridge is actually the third major bridge at this crossing as a concrete arch also known as Dragon Gate Bridge existed from 1987 to 2008 before the rising waters of the 3 Gorges reservoir forced its removal. The concrete arch gateway marked the starting point for millions of tourists on their boating adventure up the most spectacular tributary of the entire Yangtze River 3 Gorges region - the Daninghe.

Known as the Lesser Three Gorges to differentiate it from the Yangtze River, a trek up the Daninghe reveals more than just a tour of several of the region's most spectacular bridges. The initial Dragon Gate gorge has many wonders beginning with glass plank walkways and Karst rock stalactites tagged with colorful names like Monkey Fishing in the Air and Fairy Peach Peak.

Dragon Gate was the first bridge in China to be built by the rotation method where the two halves of the arch are constructed just above the ground on either hillside and then rotated out over the canyon in one careful maneuver and then closed at the crown. In this early photo you can see part of the temporary arch support foundations next to the bridge on both sides of the hill slope.
