# Gyeongbu Expressway

The Gyeongbu Expressway (Korean: 경부고속도로; Asian Highway Network AH 1) is the second oldest and most heavily travelled expressway in South Korea, connecting Seoul to Suwon, Daejeon, Gumi, Daegu, Gyeongju, Ulsan and Busan. It has the route number 1, signifying its role as South Korea's most important expressway. The entire length from Seoul to Busan is 416 kilometers (258 mi) and the posted speed limit is 100 kilometers per hour (62 mph), enforced primarily by speed cameras.

## History

Inspired by the Autobahn during a trip to Germany, South Korean President Park Chung Hee proposed the construction of the Gyeongbu Expressway as an election pledge in 1967.$^{:26}$
* February 1968 - Construction begins at the behest of South Korean President Park Chung Hee, who named Park Myung-keun in charge of construction.
* 21 December 1968 - Seoul-Suwon segment opens to traffic.
* 30 December 1968 - Suwon-Osan segment opens to traffic.
* 29 September 1969 - Anseong-Cheonan segment opens to traffic.
* 10 December 1969 - Cheonan-Daejeon segment opens to traffic.
* 19 December 1969 - Busan-Daegu (via Gyeongju) segment opens to traffic.
* 7 July 1970 - The last segment, the mountainous Daejeon-Daegu segment, opens to traffic, completing South Korea's first long-distance limited access expressway.
* December 1987 - Work begins to widen to six lanes in selected areas. Some areas are widened to 8 or 10 lanes by 1996.
* February 1995 - Bus-only lane (essentially an HOV-9) established between the northern terminus and Sintanjin for important holidays.
* 14 July 2000 - Eight vehicles, including three buses and a five-ton truck, collide near Gimcheon, killing 18 and injuring over 100.
* 25 August 2001 - All expressways in South Korea reorganize under a pattern modeled after the United States' Interstate Highway System. The Gyeongbu Expressway's route number of 1 is the only one not to change; however, its kilometer markers change from a north–south progression to south–north.
* December 2002 - Korea National Expressway Corporation passes control of the northernmost 9 km stretch of expressway (between Yangjae and Hannam Bridge) to the City of Seoul.
* 1 July 2008 - Bus lane enforcement between Seoul and Osan (Sintanjin on weekends) becomes daily between 6 AM and 10 PM. On 1 October this is adjusted to 7 AM to 9 PM weekdays, 9 AM to 9 PM weekends.
