Suvarnabhumi Airport is located on a 3,100 ha site in the Samut Prakarn province of Thailand at Nong Ngu Hao (Nongnughao translated as Cobra Swamp), 30km east of Bangkok. Road access to the new airport will be provided by a series of new highways connected to Bangkok's existing outer ring road. The main access road is an elevated 2 x 5 lane road that leads from the passenger terminal through the northern part of the site to the new Bangkok–Chonburi highway.

The construction of the City Airport Terminal in Makkasan and a 28.6 km high-speed rail link to the new airport started in July 2005 and are planned for completion in November 2007. The airport express, informally known as the Pink Line and operated jointly with SRT's planned Red Line commuter service, will connect with the BTS Sukhumvit Line and MRT Blue Line at Phaya Thai and Phetchaburi stations respectively, offering airport-bound passengers a fast 15-minute limited stop journey from the city.

Free shuttle bus service is provided for passengers and airport staff. Expess route connects the main terminal directly to the transport center. Ordinary route connects to other airport facilities. For passenger convenience shuttle buses serving Suvarnabhumi airport are low-floor type.
