Bangna-Suvarnabhumi Line

The Bangna-Suvarnabhumi Line (Thai: รถไฟฟ้าบีทีเอส สายบางนา-สุวรรณภูมิ) is a proposed light rail line in Bangkok that would provide service from Bangna to Suvarnabhumi Airport. Although not included in the Mass Rapid Transit Master Plan, in December 2015 the BMA said it would push for its construction and would propose it to the cabinet in the near future. In April 2016 deputy governor Amorn Kitchawengkul said the project would take 3–6 years and cost THB 20 billion. The project would relieve congestion on the Bang Na – Trat road.
