Bridging rugged mountain valleys, the 942-meter Miaojialiang Grand Bridge has been successfully closed🌉 This landmark viaduct is a vital part of the Xi’an-Chongqing high-speed rail. Building such a massive structure deep in steep terrain shows extraordinary engineering courage. China keeps rewriting what mountain infrastructure can achieve. #China #Infrastructure
