[Asia Economy Reporter Jo In-kyung] Seoul City announced on the 17th that following the opening of two lanes in the Suseo direction at the Maehun Underpass on the Gangnam Circular Urban Expressway last month, the two lanes in the opposite Gwacheon direction will be fully opened from 2 p.m. on the 19th.

As a result, the entire 19.7 km section of the Gangnam Circular Urban Expressway connecting the southern part of Seoul from Doksan-dong, Geumcheon-gu to Guryong Tunnel Intersection in Gangnam-gu will be connected. Previously, one lane for using the Maehun Underpass from the Gwacheon (Anyang) direction to the Suseo direction was opened on the afternoon of the 11th.

The Maehun Underpass, located between Seonam IC on the Gangnam Circular Urban Expressway and Yeomgok-dong West Underpass (Yangjae-dong, Seocho-gu), is part of the construction of Section 8 of the Gangnam Circular Urban Expressway. It consists of five lanes in both directions, extends 900 meters, and involved a construction cost of approximately 58.2 billion KRW.

Using this underpass allows vehicles to pass through Yangjae IC and Yeomgok Intersection without stopping at traffic signals, which is expected to reduce interference with vehicles using the Gyeongbu Expressway during peak commuting hours and improve the surrounding traffic flow.

The city plans to complete the restoration work above the Maehun Underpass, including the removal of the deck slab, installation of sidewalks, and road pavement, by September next year.

Kim Hong-gil, Acting Director of the Urban Infrastructure Headquarters of Seoul City, explained, "With the full opening of the Gangnam Circular Urban Expressway, traffic conditions in the southern Seocho and Gangnam areas centered around Yangjae-daero will be greatly improved."
