When setting speed limits for roads in Hong Kong, the Administration has regard primarily to safety and takes into consideration a number of factors including

(i)

(ii)

(iii)

the length of the route;

topography and geometric design of the route; and

road surface characteristics.

It is on this principle that the speed limits of the roads connecting Route 3/ Route 9 have been determined. It should be noted that permitting higher vehicle speed would not necessarily increase road capacity as a longer distance between vehicles is required for safe braking,

Routes 3 and 9 join Tuen Mun Road at the northern end and the Western Harbour Crossing and the road network on Hong Kong Island at the south. Because of the topography, design and safety, the speed limits on Tuen Mun Road and on Hong Kong Island cannot be increased.
