Chao Phraya Sky Park
Chao Phraya Sky Park () 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. History 

This viaduct was the site of the construction of the Lavalin Skytrain project, which was the first electric train line of Bangkok. The construction route had been studied since 1979 until the construction contract was signed in 1990. After only 2 years, Lavalin Company was facing financial problems so the project had to be abandoned, leaving only the bridge. Subsequently, Bangkok Metropolitan Administration teamed up with the Urban Design and Development Center (UDDC), as well as the Office of the Health Promotion Fund and Chulalongkorn University to develop the landscape in the Kudi Chin area to the Khlong San area. Therefore, there developed a project to renovate the remains of this abandoned viaduct to be a public park in the middle of the river. It was designed by N7A, in charge of architecture, and LandProces,s in charge of landscape architecture, which was originally named Phra Prajadhipok Bridge Sky Park. It was later forwarded to Bangkok in 2018 by SGR Company, which bid for the project at a price of 122 million baht. The project was constructed in March 2019 and the contract expired in March 2020. Bangkok Metropolitan Administration organized a contest to name this park in the middle of the river again. The name that won the contest was "Chao Phraya Sky Park" and the park officially opened on June 25, 2020. Design 
An architect from N7A named Mr. Chakdao Navacharoen said the initial issue was quite challenging. The first building was constructed for the electric train project. The first drawback is that the project's placement is between a driveway with three lanes on both sides, making the bridge's walkway extremely small. However, the project's location is a benefit. Although it is obstructed by traffic on the Phra Pok Klao Bridge, it is still possible to see both the Memorial Bridge and Wat Arun. Location
