World’s longest-spanning railway arch bridge completed in SW China

Chinese construction firms have built the world’s longest-spanning railway arch bridge. The grand bridge was fully erected across the Nujiang River in southwest China’s Yunnan province on Dec. 10, 2018.

Measuring 1,024 meters long and nearly 24.9 meters wide, the bridge, which is about 230 meters above the Nujiang River, looks like a beautiful rainbow spanning atop the river and the valley below. About 46,000 tons of steel was used to build the bridge, 6.5 times the weight of the materials used to construct the Eiffel Tower.
