Ratchadaphisek Road (Thai: ถนนรัชดาภิเษก,), also known as Bangkok Inner Ring Road (Thai: ถนนวงแหวนรอบในกรุงเทพมหานคร) is a major road in Bangkok, Thailand. Conceived in 1971 and opened in 1976, it connects earlier portions including Asok Montri, Wong Sawang and Charan Sanitwong Roads to form the city's inner ring road system. The road's name comes from the celebration 25th year of a monarch's reign of King Bhumibol Adulyadej.
Ratchadaphisek Road crosses major traffic arteries such as Sukhumvit Road and Sirat Expressway.
The Ratchadaphisek district stretches from the junction with Rama IX Road to the one with Sutthisan Winitchai Road. It is a well-known entertainment area,[1] including shopping complexes such as The Esplanade, cinema complexes such as Major Cineplex, a night bazaar, and night markets as well as love hotels.
Along with Royal City Avenue (RCA) and Patpong, portions of the district are designated as "entertainment zones" and thus allowed to remain open until 02:00.[2]
The MRT Blue line runs on Ratchadaphisek Road in two long segments; an elevated section in Thonburi between Tha Phra and Bang O stations, and an underground section between Lat Phrao and Queen Sirikit National Convention Centre stations. Ratchadaphisek MRT station itself is in the northeast section of Ratchadaphisek Road, in the Din Daeng district.[3]
