Seoul City announced on the 11th that Seosomun Elevated Road will operate detour bus routes starting from the 17th due to demolition and reconstruction work.
Seosomun Elevated Road was decided to be demolished after receiving a 'safety grade D' designation, which requires urgent repair work. Seoul City plans to gradually reduce lanes to alleviate inconvenience for citizens and traffic congestion.
First, starting on the 17th, one lane from the city hall towards Chungjeongno will be closed. As a result, a total of 20 metropolitan bus routes, including 9 from Gyeonggi Province and 11 from Incheon, will operate detours.
The 9 routes from Gyeonggi Province will detour using a total of 4 routes including Tongil-ro~Sajik-ro~Sejong-daero~Saemunan-ro. Routes 1002, 1004, 8600, 8601, and G6005 will go via Tongil-ro~Sajik-ro~Sejong-daero~Saemunan-ro. Additionally, M6117 and Leeum 1 will travel through Daehung-ro and Baekbeom-ro, while P9110 will go through Sogong-ro and Sejong-daero, and P9211 will detour via Sejong-daero and Namdaemun-ro.
The 11 routes in Incheon will operate via routes that turn around at Hongdae Entrance Station, Sinchon Station, and Dangsan Station.
Routes 1000, 1100, 1101, 1200, 1400, 1500, and 1601 will turn around at Hongdae Entrance Station, M6724 will turn at Sinchon Station, and routes 1300, 1301, and 1302 will turn around at Dangsan Station.
From September 21, when Seosomun Elevated Road is fully closed, 11 routes, including Seoul's local and trunk buses and late-night buses, will implement detour operations.
The 5 routes, including 172, 472, N62, N73, and N51, which previously passed through Seosomun Elevated Road, will detour via Chungjeongno~Tongil-ro~Sejong-daero. Additionally, the 2 routes, 600 and 602, which previously passed through Seosomun Elevated Road in one direction, will detour using Sejong-daero~Tongil-ro~Chungjeongno.
Route 603 will operate via Chungjeongno~Saemunan-ro~Sejong-daero, and 6701 will operate via Tongil-ro~Chungjeongno.
Route 7011, which previously turned right under the elevated road, will detour via Saemunan-ro~Chungjeongno, and Seodaemun 06 will turn around at Seosomun History Park.
However, the detour timing and routes may be adjusted depending on traffic system changes and congestion on the roads. Further details can be found on the websites of Seoul City, Gyeonggi Province, Incheon City, and other relevant local governments.
Yeojang-gwon, Seoul City's Transportation Office Director, said, "Since traffic congestion near the construction site is expected during the construction period, please use alternative means of transportation such as the subway." He added, "We will mobilize all administrative resources to reduce inconvenience for citizens."
