Having uncogested highway doesn't preclude ones from building double-decker highways. You see they are taking up so much space in hkskyline's photo:
Route 3 Construction thread
West Kln Expressway is a big pain, particularly the section near Yau Ma Tei. It occupies almost the size of Kowloon Park.
See Google's map
Whether it is the cost that matters, or simply the engineers in HK gov't don't realise they could save space in that way??
