Chao Phraya Sky Park (Thai: สวนลอยฟ้าเจ้าพระยา) is an elevated, linear park in Bangkok, built on the central viaduct that used to be the structure of the failed Lavalin Skytrain project. The path, which is about 280 meters in length, was designed by Urban Design and Development Center, Chulalongkorn University, and opened in June 2020. The Sky Park is considered the first sky park in Southeast Asia.
