Is Sichuan Highway Planning, Survey, Design and Research Institute OK?

All right. Sichuan Highway Planning Survey and Design Institute is good, because it has reached the domestic leading level in the fields of mountain highway survey and design, bridge design technology, mountain tunnel design technology, comprehensive technology of highway earthquake resistance and disaster reduction, and scientific research and experiment. They have created a number of classic projects such as Ya 'an-Xichang Expressway, Ganhaizi Bridge, the world's longest concrete-filled steel tubular truss bridge, and Queershan Tunnel, the world's highest extra-long highway tunnel. These projects not only reflect the technical strength of the institute, but also win wide acclaim. That's great.
