The concrete part linking pillars of the project that collapsed is near railway tracks in Chatuchak district and about 100 meters from Wat Samiennaree.
The Bt 80 billion project was approved in 1990 and was a joint project of the Thai authorities and and the Thai subsidiary of Hopewell Holdings of Hong Kong.
The construction ceased in August 1997 during the Asian financial crisis, with only around 10% complete. The project was formally terminated by the Cabinet in 1998.
