Notes: For more information on strategic routes and their update, see 'Further Reference Materials'.

Hong Kong strategic routes, including most trunk roads and expressways, have route numbers which enable drivers to quickly find the most convenient and direct route from one district to another. Route number shields as well as exit numbers are included on direction signs to guide drivers. Chainage markers are also installed at regular intervals to advise your position along the strategic routes.

Ten routes have been designated under the route numbering system. The three north-south routes (Routes 1, 2 and 3) pass through the three crossharbour tunnels, and their numbering sequence follows the opening of the tunnels (i.e. Cross-Harbour Tunnel, Eastern Harbour Crossing and Western Harbour Crossing). The six east-west routes (Routes 4, 5, 6, 7, 8 and 10) have sequences starting from south to north. The circular Route 9 circumscribes the New Territories.
