Road Network

Hong Kong's road network is amongst the most heavily used in the world. In December 2025, the public road network of Hong Kong is about 2,269 km in total length – 450 km on Hong Kong Island, 484 km in Kowloon and 1,335 km in the New Territories respectively, with over 810,000 vehicles travelling, together with the dense development and the undulating terrain, bringing considerable challenges to the road maintenance works of the Highways Department.

The territory has 2,269 km of roads, 1,488 road structures, 24 road tunnels (including three immersed-tube harbour crossings and a subsea tunnel constructed by tunnel boring) and five major cable-supported bridges.
