List of streets and roads in Hong Kong

Hong Kong's Transport Department is responsible for management of road traffic, regulation of public transport services and operation of major transport infrastructures, while Highways Department is responsible for planning, design, construction and maintenance of the public road system.

In 2004, a new strategic route marking system was put in place, with most existing routes renumbered and exits to key places or to another route also numbered. (For example, a journey from Yau Ma Tei to the airport uses Route 3, taking Exit 5 to join Route 8. It is therefore identified as "3-5-8".) Routes 1 to 3 are cross-harbour north–south routes following the order in which the harbour tunnels were opened. Routes 4, 5, 7 and 8 run east–west, numbered from south to north. Route 9 circumscribes the New Territories. Route 10 runs from western New Territories from Route 9 and bends northward towards and passes the border to Shenzhen. However, the new system has caused some confusion to drivers used to relying on destination signs.

The routes are designated as follows:

• Route 1: Aberdeen – Wong Chuk Hang – Aberdeen Tunnel – Causeway Bay – Cross-Harbour Tunnel – Kowloon Tong – Lion Rock Tunnel – Sha Tin (to join Route 9)
• Route 2: Quarry Bay – Eastern Cross-Harbour Tunnel – Kwun Tong Bypass – Tate's Cairn Tunnel – Ma Liu Shui (to join Route 9)
• Route 3: Sai Ying Pun – Western Cross-Harbour Tunnel – West Kowloon Highway – Kwai Chung – Tsing Yi – Cheung Tsing Tunnel – Ting Kau Bridge – Tai Lam Tunnel – Yuen Long (to join Route 9)
• Route 4: Chai Wan – Island Eastern Corridor – Quarry Bay – Causeway Bay – Wan Chai – Central – Sheung Wan – Sai Ying Pun – Kennedy Town
• Route 5: Ngau Tau Kok – Kowloon Bay – Airport Tunnel – Hung Hom – Yau Ma Tei – Lai Chi Kok – Kwai Chung – Tsuen Wan (to join Route 9)
• Route 6: Reserved for future route. Proposed Central Kowloon Route – Proposed Southeast Kowloon T2 Route – Proposed Tseung Kwan O – Lam Tin Tunnel
• Route 7: Tseung Kwan O – Tseung Kwan O Tunnel – Kwun Tong – Wong Tai Sin – Sham Shui Po – Lai Chi Kok – Kwai Chung (to join Route 5)
• Route 8: Chek Lap Kok (Airport) – Tsing Ma Bridge – Tsing Yi – Stonecutters Island – Lai Chi Kok – Sha Tin to join Route 9.
• Route 9: Shing Mun Tunnel – Tai Wai – Sha Tin – Ma Liu Shui – Tai Po – Fanling – Sheung Shui – San Tin – Yuen Long – - Tuen Mun – Sham Tseng – Tsuen Wan
• Route 10: Airport – Tuen Mun, Lam Tei – Shekou, Shenzhen

The Transport Department has designated about 22 km (14 mi) of road length as exclusive "bus lanes", out of approximately 2,000 km (1,200 mi) of accessible roads.

The traffic CAM online provides near real-time road conditions for all major road users, as well as facilitating monitoring of traffic. There are about 115 closed-circuit cameras located on the routes to provide monitoring of traffic flow. Congestion is heaviest in Kowloon and along the northern shore of Hong Kong Island, where most cameras are located.
