Gourt Home::Gourt :: Seoul Subway Line 7
Seoul Subway Line 7 of the Seoul Metropolitan Rapid Transit Corporation was built 1990-96 (Jangam-Konkuk Univ.) and was completed 1 Aug. 2000 (central section 17 km. Konkuk University to Sinpung); the western section between Sinpung and Onsu was put into service on 29 Feb. 2000. This north-south line does not run through the city centre but links Gangnam directly to the northern parts of town.
The future plan is an extension to Incheon Subway Line 1 to relieve the traffic congestion in western Seoul and northern Incheon. 9 stations will be added by 2010 for the 9.8 km extension, starting from Onsu Station of Line 7 and ending at Bupyeong-gu Office Station of Incheon Subway Line 1*. Current length: 46.9 km.
