This study is to propose spatial interventions to activate port areas in the harbor city, Busan. Many ports including Busan North Port redevelopment are expected to redevelop soon. Most of them will be changed existing industrial ports to waterfront facility. However, these developments do not consider existing urban context. To resolve this problem, I suggest infrastructures and public spaces between existing urban structure and expected developments. This plan will increase accessibility to waterfront area and provide active public spaces. Especially, this study focuses on Busan North Port area. I propose an athletic park for local people and four pedestrian bridges to connect between city downtown and Busan North Port. / text
