The Lvzhijiang Bridge is a key section of the 190-kilometer-long Yuchu Expressway and the 9,000-kilometer Yunnan Highway network. With construction commencing in 2019, the project took about three years to complete. It’s expected to open to traffic by late April 2022.

Stretching 798 meters over a river valley, Lvzhijiang Bridge’s mere length may not sound all that extreme when compared to some of the world’s longest bridges. But the complexity of the project is earning it recognition as an engineering marvel.

The maximum speed limit on the bridge is 100 kilometers per hour.

Built in a mountainous V-shaped valley, it is the world’s first single-tower, single-span suspension bridge; it’s only held up by one tower and is supported at both ends by cables. There are no additional columns, giving it a dramatic, gravity-defying look.

The bridge’s single span — the distance between two supports — is 780 meters. In addition, officials say it has the world’s steepest tunnel anchorage, which is angled at 54 degrees.

The bridge links neighboring Yuxi City and Yunnan’s Chuxiong Yi Autonomous Prefecture and will dramatically shorten the journey time.
