Stung Treng Bridge, Box girder bridge in Stung Treng Province, Cambodia.

Stung Treng Bridge is a concrete bridge across the Mekong River near Stung Treng town, opened in 2015. It was built by Shanghai Construction Group and Guangzhou Wanan Construction Supervision, Co. Ltd. as the sixth Cambodia-China Friendship Bridge, with funding from the Chinese government.

The bridge was completed in April 2015 by Shanghai Construction Group and Guangzhou Wanan Construction Supervision. Chinese government funding supported the project as part of broader regional infrastructure development.

The bridge is the sixth Cambodia-China Friendship Bridge, a designation that ties it to a series of Chinese-funded crossings in Cambodia. Its April 2015 inauguration was attended by Prime Minister Hun Sen and Chinese Ambassador Bu Jianguo, and the structure is used daily by people crossing between Stung Treng town and the province's rural districts.

The bridge carries the road across the Mekong just outside Stung Treng town, linking the provincial town with the province's rural areas and onward toward Preah Vihear Province and the Lao border. It gives a faster, cheaper crossing than the river ferries it replaced, for both vehicles and trade traffic.

The bridge is officially the sixth Cambodia-China Friendship Bridge. Its US$2,558,125 cost was covered by a concessional loan from the Exim Bank of China, and construction was carried out by the Shanghai Construction Group with Guangzhou Wanan Construction Supervision as supervisor.
