The 968-meter bridge in Fusui County of the city of Chongzuo is the world’s longest-span concrete-filled steel tube arch highway bridge under construction.

The successful completion of the arch laid a solid foundation for the opening of an expressway from Nanning Wuxu International Airport to Long’an County in Guangxi.

The expressway is expected to open this year.
