[Asia Economy Reporter Kangwook Cho] Korea Expressway Corporation announced on the 1st that the new entrance and exit ramps at Songpa Interchange on the Seoul Metropolitan Area 1st Ring Expressway will be partially opened from 16:30 on the 3rd.

The new entrance and exit ramps are located about 200 meters up from the existing location towards Namhansanseong (Seongnam), and roads directly connecting ‘Wirye (Entrance) → Pangyo (Main Line)’ and ‘Guri (Main Line) → Wirye (Exit)’ have been added.

Along with this, by undergrounding the expressway connection section to separate vehicles entering the expressway from those using general roads, traffic congestion around the frequently congested Bokjeong Station intersection area is expected to be dramatically improved.

Additionally, the section from Songpa Interchange to Seo Hanam Interchange operates a shoulder lane system to alleviate mainline congestion, while applying low-noise and water-permeable pavement to enhance driving stability during rain and reduce road noise.

Construction of the Songpa Interchange improvement project, which began in 2016 with a total project cost of 182.5 billion KRW, is part of the Wirye New Town metropolitan traffic improvement plan, and is expected to be fully opened by the end of this year after additional works such as installation of soundproof facilities are completed.

A Korea Expressway Corporation official said, "The new entrance and exit ramps are being partially opened to quickly resolve public inconvenience," adding, "However, since additional construction is ongoing, safe driving is required when passing through the section."
