Jamsu Bridge, Road bridge in Seocho district, Seoul, South Korea

Jamsu Bridge is the lower deck of a two-level crossing over the Han River in Seoul, linking Yongsan District with Seocho District. The pedestrian bridge is 795 m long and 18 m wide, and it sits only a few metres above the waterline beneath the Banpo Bridge built above it in 1982.

The bridge was built in 1976 as part of Seoul's expanding infrastructure. Within a few years, an additional bridge was constructed directly above it, creating an unusual layered crossing over the river.

The bridge becomes a gathering space during seasonal events, with local markets and food vendors setting up along its pedestrian walkways. Visitors witness everyday city life as people gather to shop and eat together.

Visitors can walk across or rent bicycles from the nearby park to cross the bridge. The experience is most pleasant outside rush hours, when the crossing is less crowded and easier to navigate.

The lower deck was reshaped into an elevated arch in 1986 so tourist cruise ships could pass beneath it. It is 795 m long and 18 m wide, and in autumn it hosts a market with live music and food trucks.
