The Bangkok Elevated Road and Train System (BERTS, Thai: โครงการระบบการขนส่งทางรถไฟยกระดับในกรุงเทพมหานคร), commonly known as the Hopewell Project (โครงการโฮปเวลล์) after main contractor Hopewell Holdings, was a failed project to build an elevated highway and rail line from central Bangkok to Don Mueang International Airport. Construction started in 1990, but was suspended by the 1st government of Anand Panyarachun in 1992, and was finally halted by legal acrimony in 1997 with only 10-13% complete. The project was cancelled in 1998. Due to its resemblance to standing stones, it has been comically nicknamed "Thailand's Stonehenge".
The 80 billion baht (US$3.2 billion) project was approved on 9 November 1990, without a feasibility study or clear timeline for completion, as a joint project of the Thai Ministry of Transport, the State Railway of Thailand (SRT), and the Thai subsidiary of Hopewell Holdings of Hong Kong. There were to be three phases: the first a north-south line from Hua Lamphong Railway Station, Bangkok's main train station, to Don Mueang International Airport; the second an east-west line from Taling Chan District to Hua Mak; and the third a spur to the port. Totaling 60 km, all three were to be built on top of existing SRT train lines.
Rumors of corruption swirled around the project from the outset. The first part of the project was due to be in operation by December 1995, with the rest completed by December 1999. However, construction ceased in August 1997 during the Asian financial crisis, with only around 10% complete.Gordon Wu of Hopewell blamed slow land acquisition on the Thai government, while Thai officials stated that Hopewell had simply run out of money. Both sides demanded financial compensation and threatened to sue the other for breach of contract, with Hopewell claiming the work had cost it US$575 million. The project was formally terminated by the Cabinet in 1998.
