# Local Route 23 (South Korea)

Local Route 23 Cheonan–Seoul Line (Korean: 국가지원지방도 제23호선 천안 ~ 서울선) is a local route of South Korea that connecting, Cheonan, South Chungcheong Province to Mapo District, Seoul.

## History

The route was originally planned as part of an extension of National Route 23 from Cheonan to Munsan, but due to a lack of funding, the route was never upgraded and was designated as a state-funded local route on 19 July 1996 running from Cheonan to Paju, replacing Local Route 315. On 17 November 2008, the section from Seoul to Paju was upgraded to National Route 77, shortening Route 23 to its current configuration.
