Yellow Line extension passes EIA report hurdle 1 published : 27 Jan 2021 at 06:11 1 The proposed extension of the MRT Yellow Line between Ratchadaphisek and Ratchayothin intersections has passed its Environmental Impact Assessment (EIA). Transport Minister Saksayam Chidchob said the project's EIA report was approved by the National Environmental Board (NEB) on Tuesday. The extension is expected to benefit commuters by providing a connection from the Yellow Line -- which will link Lat Phrao in Bangkok and Samrong in Samut Prakan -- to the city's other electric train lines, namely the Blue and Green lines, the Airport Rail Link, as well as the Orange Line, which is currently under construction.
