UK firms this week lost out on millions of pounds of work when Hong Kong law makers blocked the proposed HK-22bn (£2.8bn) Route 10 highway.
Construction supervision contracted to Maunsell, Mott Connell and Scott Wilson will now be cancelled.
The decision to scrap the scheme - running across the north west New Territories connecting new road and bridge links to China with the rest of the highway network - came after the legislator refused to sanction the £12M detailed design of the northern section.
Mott Connell in joint venture with Scott Wilson was responsible for the detailed design and construction supervision of the southern section of Route 10 running between Tsing Lung Tau and So Kwun Wat.
Maunsell was part of a larger group responsible for the detailed design and construction supervision of the Tsing Lung suspension bridge that would link the New Territories with Lantau Island.
Cheaper proposals will now be considered including that of Sir Gordon Wu, former head of Hopewell Holdings and now chairman of the Port and Maritime Board, for a north-south bridge and tunnel link between Tuen Mun and Chek Lap Kok airport.
