The Hau Hoi Wan Trunk Road, Hong Kong is the 4th land corridor connecting Hong Kong and Shenzhen. The south section as discussed herewith is a part of the Trunk Road- Proiect and is mainly composed of viaducts totally made up of 92 spans, of which 62 spans are precast concrete girders with the longest span 43 m and 30 spans are cast-in-place concrete girders with the longest span 80 m. The concrete box girders of the precast spans of the viaducts are constructed with short-line match method, and erected with overhead launching gantry and RMD scaffoldings.
