The second phase of the Subway Line 9 construction project, which is projected to run from Nonhyeon-dong to the Jamsil Sports Complex in southern Seoul, is now progressing smoothly. The work that has attracted the most attention involves the construction of a subway station under the current Jamsil Sports Complex Station on Line 2.
As Subway Line 2 currently carries about 2.3 million passengers every day, it cannot be shut down just because of the work on Phase 2 of Line 9. As such, a completely new construction method has been adopted to ensure successful completion of this section of the line.
The construction of the station has been described as “one of the most challenging subway construction projects ever undertaken” by Discovery Channel (USA), which filmed the project in March and will broadcast it on its 3-D channel this fall not only in the U.S. but also in many other parts of the world.
The Seoul Metropolitan Government is considering exporting the subway construction technologies it has accumulated over the past 38 years since 1974, when Subway Line 1 was launched as Korea’s first ever subway line, to major cities in Southeast Asia, the Middle East, and Latin America.
Recently, 94 journalists and other people related to subway construction, including foreigners from Singapore, Colombia, India, Saudi Arabia and Hong Kong, paid a visit to the construction site where a new construction method is being used to complete the station beneath the existing station on Subway Line 2.
Seoul Metropolitan Government operates nine subway lines covering 316.9km of track, as well as a national railway line in Seoul comprising 111.1km of track, 292 stations and 3,659 carriages.
The second phase project of Line 9 involves the construction of five subway stations between Nonhyeon-dong, Gangnam-gu and the Jamsil Sports Complex south of the Hangang River. The project kicked off in June 2008 and will be completed in 2014.
