The Seoul Metropolitan Government said Sunday that it has begun construction on Phase 1 of a road restructuring project along the east side of Tancheon stream in Songpa-gu, near the Olympic Familia apartment complex. The city expects the work to make roads in the area more convenient and safer for users.

The city has restricted vehicle access to certain sections of the road since Saturday and is operating a temporary detour. The restrictions and the detour are expected to remain in place until the second half of 2030, when construction is scheduled to wrap up.

The Tancheon east road restructuring project was launched to address rising traffic demand from large-scale development in southeastern Seoul, including the Wirye new town and the Munjeong district.

The project will reconfigure 4.9 kilometers of road from the northern end of Samseong Bridge in Songpa-gu to the Dongnam-ro intersection, improving connectivity between Tancheon-dong-ro and Dongnam-ro and easing congestion on the Eastern Arterial Road and Songpa-daero.

The first section to enter full construction runs 0.6 kilometers from the Gwangpyeong Bridge intersection to the Dongnam-ro intersection. The existing road — split between a four-lane carriageway below the embankment and a two-lane carriageway above it — will be consolidated into a single six-lane road.

Along roughly 350 meters of that stretch, an underpass will be built, with a green ecological path of about 5,000 square meters connecting to Tancheon stream created above it.

The construction has restricted vehicle access to parts of Jungdaero 2-gil and Tancheon-dong-ro since Saturday. To keep traffic moving and minimize congestion, the city plans to redirect drivers to a newly built two-lane temporary bypass along the Tancheon stream bank.

Updated routes will be posted on variable message signs and banners at the site, and real-time traffic conditions can be checked through the Seoul Metropolitan Government's traffic information system Topis, as well as major navigation apps including T Map and Kakao Map.

Im Chun-geun, head of the Seoul Metropolitan Government's Urban Infrastructure Headquarters, said the city would do its best to manage the site and minimize traffic disruptions. "We ask citizens to actively cooperate by using the alternative and detour roads and driving safely," Im said.
