Songdo (Korean: 송도), officially known as Songdo International Business District (Songdo IBD), is a smart city built on 600 ha (1,500 acres) of reclaimed land along Incheon's waterfront, 30 km (19 mi) southwest of Seoul, South Korea. It is connected to Incheon International Airport by a 12.3 km (7.6 mi) reinforced concrete highway bridge called Incheon Bridge. Along with Yeongjong and Cheongna, it is part of the Incheon Free Economic Zone.
The Songdo smart city features amenities across the district. Homages to international architectural hallmarks, such as New York City's Central Park and Venice's waterways, are planned to be incorporated. Many of the existing buildings were constructed as LEED-certified space, the green building certification of the United States Green Building Council.
