Expressways in South Korea

Highway bus lane on Gyeongbu Expressway in the Republic of 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 Expressways 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.

• Belt lines have three-digit route numbers where the first digit matches the respective city's postal code.

• 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.
