Dangsan Railway Bridge carries Seoul Subway Line 2 across the Han River between Dangsan Station and Hapjeong Station. On clear days, trains crossing the bridge offer views of Yeouido, the National Assembly, and Seonyudo Park. The bridge opened in 1984 and was fully rebuilt for safety, taking its current form in 1999 at a length of 1,360 meters. Seeing a train pass from Gangbyeonbuk-ro requires timing.
