The Hong Kong Strategic Route and Exit Number System
: 香港主要幹線及出口編號系統) is a system adopted by the Transport Department
of the Hong Kong Government
to organise the major roads in the territory into Routes 1 to 10 for the convenience of drivers. When the system was first implemented in 2004
, the government launched a large campaign to promote it to the public. One of the slogans is "Remember the Numbers; Make Driving Easier" (認路記號碼，唔使路路查).
The system comprises nine major series of roads in Hong Kong, numbered Routes 1 to 5 and 7 to 10, which can be classified into three categories: the three north-south routes, the five east-west routes and the New Territories
Circular Road. The route numbers are represented as black on yellow "road-shields"
on overhead roadsigns.
The system also implemented exit numbering
on the aforementioned routes. The exits of each route are numbered sequentially; some exit numbers are suffixed with a letter of the alphabet. Exit numbers are indicated by white in black rectangular boxes on overhead and roadside signs.
