The Sports Authority of Thailand met on Thursday to discuss the concept, and confirmed that a 5.995 kilometre circuit would be created near the Royal Thai Naval Dockyard in Bangkok.
The circuit will run past several major tourist destinations, including the Grand Palace, the Temple of Dawn and Victory Monument.
Final approval for the track configuration is now set to go to government for sign-off within the next few months.
Thailand has been chasing the race for several years, with Red Bull a keen backer to hold a night race in the country's capital.
The event will almost certainly attract a bumper crowd, with Mark Webber having drawn 100,000 spectators to a street demo in the city back in 2010.
