The project, which winds through hilly terrain with numerous curves across 106 bridges totaling 16.4 kilometers, is Guangdong's first highway reconstruction and expansion project in a mountainous area. The varied topography required 7,303 precast beams spanning a wide range of types, lengths, and angles, a production challenge the project addressed through two intelligent beam yards.
