[Asia Economy Reporter Lim Cheol-young] The Seoul Metropolitan Government announced on the 18th that it has completed the expansion work of the 1.1 km section of Nambusunhwan-ro from Gwangbokgyo to Saseonggyo (formerly Anyanggyo) in Guro-gu, expanding from 4 lanes to 6 lanes in both directions, and will fully open it from 6 a.m. on the 20th.

With this opening, the bottleneck on the Nambusunhwan-ro section between Gwangbokgyo and Saseonggyo is expected to be resolved, significantly improving traffic congestion during rush hours. The average vehicle travel speed will increase from the current 32 km/h to 37.6 km/h, about 5.6 km/h faster, and the service level, rated from A to F, will improve from grade D to grade C, according to the Seoul Metropolitan Government.

The "Gwangbokgyo~Saseonggyo Road Expansion Project" began in April 2016 and was completed after 5 years and 8 months (68 months). Saseonggyo, originally built in 1977, was demolished and reborn as a beautifully designed arch bridge (275 m). The number of piers within the exclusion zone was reduced from 8 to 4, and the spacing between piers was widened from 25 m to 37.5 m by installing an arch bridge, which is expected to become a landmark representing Anyangcheon with its elegant appearance.

Gwangbokgyo and the surrounding roads were expanded to 6 lanes (835 m). A new bridge 9.3 m wide was constructed in the Oryu direction, and a pedestrian bridge 4.4 m wide was additionally installed in the Guro direction. Sidewalks were newly constructed on both sides of the road, greatly improving the pedestrian environment and allowing convenient use of the riverside space. Although the road was deregulated as a car-only road in June 2014, sidewalks were not created, causing significant inconvenience to residents using Mokgamcheon and Anyangcheon.

Lee Jeong-hwa, Director of the Urban Infrastructure Headquarters of Seoul, said, "The resolution of the bottleneck section on Nambusunhwan-ro will greatly alleviate traffic congestion, and connecting the previously disconnected sidewalks will allow citizens to use the Anyangcheon riverside space more conveniently." She added, "We thank the citizens for enduring the inconvenience during the long construction period. We will do our best to make Seoul a convenient and safe city for its citizens."
