The Banghwa Bridge (Korean: 방화대교) is a bridge in South Korea. It crosses the Han River, connecting the Gangseo District, Seoul with Goyang, Gyeonggi Province. The bridge is a part of the Incheon International Airport Expressway. At over 2.5 km in length, it is the longest bridge to cross the Han River. Though mostly a girder bridge, the middle 540m section is an arch truss, resembling the shape of an airplane taking off.
