Roads and expressways in South Korea

Expressways in South Korea were originally numbered in order of construction. Since August 24, 2001, they have been numbered in a scheme somewhat similar to that of the Interstate Highway System in the United States; the icons of the South Korean highways are similar to the US red, white and blue.

• Arterial routes are designated by two-digit numbers, with north-south routes having odd numbers, and east-west routes having even numbers. Primary routes (i.e. major thoroughfares) have 5 or 0 as their last digit, while secondary routes end in other digits.

• Branch routes have three-digit route numbers, where the first two digits match the route number of an arterial route. This differs from the American system, whose last two digits match the primary route.

• Belt lines have three-digit route numbers where the first digit matches the respective city's postal code. This also differs from American numbering.

• Route numbers in the range 70-99 are not used in South Korea; they are reserved for designations in the event of Korean reunification.

• The Gyeongbu Expressway kept its Route 1 designation, as it is South Korea's first and most important expressway.
