TREE NEWS update: The Tianfu Furong Bridge, a key control project of the Chengdu-Leshan expressway expansion, completed a dual-span synchronous rotation in the early hours of September 17. Each span is 116 meters long and 36.1 meters wide, with a combined rotating weight of 86,000 tonnes, crossing the Chengdu-Guiyang high-speed railway and the Chengdu Ring Expressway. The expansion project runs 136 km from Chengdu to Leshan, with over 80% of sections already open to traffic.

AI take

The engineering milestone matters less than what it unlocks: this was a control project, meaning the Chengdu-Leshan expansion's remaining sections likely hinge on it. With over 80% already open, the question is whether the final stretches now move on schedule. For regional logistics and construction-supply chains along the corridor, that timing is the practical signal to watch.
