Bangkok Elevated Road and Train System

The Bangkok Elevated Road and Train System (BERTS, Thai: โครงการระบบการขนส่งทางรถไฟยกระดับในกรุงเทพมหานคร), commonly known as the Hopewell Project (Thai: 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 first government of Anand Panyarachun in 1992, and was finally halted by legal acrimony in 1997 with only 10-13% complete.
