Seoul Southern Loop Road Widened to 9 Lanes Upon Completion of Municipal Road Grading Project
en.Wedoany.com Reported - The Seoul Metropolitan Government announced on April 29 that the "Southern Loop Road Grading Project," carried out over a 1.1 km section from Maebong Elementary School to Oryu IC in Guro-gu, will be fully completed on the 30th. The area around Gaebong 1-dong Intersection, where this municipal road is located, was previously divided by retaining walls up to three meters high, making access inconvenient. It has now been transformed into a pedestrian-centered space.

Seoul City has invested a total of 70 billion won in this municipal road project since March 2016. To alleviate chronic congestion, the road width has been expanded from the original 30 meters to a maximum of 46 meters, and the six-lane road has been expanded to nine lanes, including auxiliary lanes. The Oryu IC bridge has also been expanded from its original five lanes (two-way) to eight lanes, including auxiliary lanes, allowing for smoother vehicle flow compared to before. In February this year, Seoul City implemented all-direction left turns at Gaebong 1-dong Intersection, adjusting a traffic system that had previously relied on detours and U-turns.
The pedestrian environment was simultaneously improved. New sidewalks were installed in sections that previously lacked them, and existing underground pedestrian passages were converted to surface-level crosswalks. A large existing underpass was converted into a pedestrian-only passage, and a separate large vehicle-only underpass was newly built, separating pedestrian and vehicle circulation routes.
Lim Chun-geun, head of the Urban Infrastructure Division at Seoul City, stated, "We expect this municipal road project will serve as more than just a simple road expansion, becoming an opportunity to connect severed areas and ensure residents' right to walk safely."
