In South Korea, highways that are managed by the provincial governments are called Local highways (Korean: 지방도; Hanja: 地方道; RR: Jibangdo).
There are some 2-digits local highways, called State-funded local highways (Korean: 국지도; Hanja: 國支道; RR: Gukjido; short term of Korean: 국가지원지방도; Hanja: 國家支援地方道; RR: Gukga Jiwon Jibangdo).
These highways are basically managed by province level, but its routes are designated and controlled by the South Korean government.
Also, most of 2-digits Local highways stand for planned extension route of the same-number national highways or candidates for upgrading to national routes.
A lot of Local highways of Gyeonggi Province were changed in 1996 and 2005.
