The planned 3-kilometre extension from Si Rat station to Muang Thong Thani has passed an environmental impact assessment (EIA) and will be sent to Cabinet in November, said the Mass Rapid Transit Authority (MRTA). 
The Pink Line will run 34.5 kilometres from Nonthaburi’s Khae Rai Intersection to Minburi district in Bangkok. 
The contractor, BTS-led consortium BRS, says work on the line is 60 per cent complete, with stations scheduled to open at the end of 2021. 
The spur-extension to Muang Thong Thani is expected to open in 2020.
