Gimpo Bridge: A Vital Link in South Korea's Capital Region
The Gimpo Bridge (Korean: 김포대교) serves as a critical piece of transportation infrastructure in South Korea. Spanning the Han River, this engineering feat provides a seamless connection between the cities of Gimpo and Goyang, facilitating the movement of people and goods across the region.
As a key component of the Capital Region First Ring Expressway, the bridge is strategically positioned to alleviate traffic congestion and enhance connectivity within the metropolitan area surrounding Seoul.

Engineering and Design
The Gimpo Bridge is designed as a girder bridge, a structure where the deck is supported by longitudinal beams (girders). To ensure durability and strength, the deck is constructed from precast prestressed concrete—a method where concrete is cast in a factory and reinforced with high-strength steel tendons that are tensioned to resist compressive loads.
The bridge features a total length of 2,280 metres and a deck width of 38.21 metres. One of its most notable engineering specifications is its longest span, which reaches 125 metres.
