In 1993, the Western Harbour Crossing Ordinance (Cap. 436) was enacted to govern the construction and operation of tunnel. Having decided to rely on the private sector, the government opted for a build–operate–transfer (BOT) model, for 30 years. Tenders for the project were invited, and was won by the Western Harbour Tunnel Company (WHTCL). The franchise was awarded for 30 years, ending August 2023. The Western Harbour Crossing Bill was also passed to award the franchise to the Western Harbour Tunnel Company to build and operate WHC.
