Roads in Hong Kong conform to the contours of the hill landscape of Hong Kong. Roads on the north side of Hong Kong Island and southern Kowloon have a grid like pattern. The roads and highways are designed to British standards. Highways conform to BritishMotorways.
<!-- Deleted image removed: -->Hong Kong's Transport Department is responsible for maintenance and control of highways and roadways.
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.
