The works include construction of a 4.6 km long dual two-lane trunk road (with about 0.6 km at grade roads, 3.3 km viaducts and a 0.7 km tunnel) connecting Sha Tau Kok Road Interchange to BCP, and the associated environmental mitigation measures, landscaping, drainage/sewerage, waterworks and utilities works.

The tunnel was excavated by drill & blast method. Large diameter concrete bored piles was adopted as the foundation of the viaducts, while using the pre-cast segmental method to erect the prestressed box girder of the viaducts.
