THAILAND: The Bangkok Metropolitan Administration announced three options for the alignment of the Silom Line metro extension on March 3.

In December the city’s Traffic & Transport Office awarded a 40m baht contract to TEAM Consulting Engineering & Management Co for a feasibility study into extending the line north from its current western terminus of Bang Wa to Taling Chan on State Railway of Thailand’s Light Red Line.

The first option envisages a 7 km route following Ratchaphruek Road, with six stations. The second route would diverge from the first by heading west along Phran Nok-Phutthamonthon Sai 4; this option would be 10 km long with eight stations. The third potential alignment would be 8 km long with six stations and head west along Boromratchonnanee Road.

Project cost is put at 10bn baht. Environmental impact studies are to be completed in 2017, and construction could begin in 2019 for opening the following year.
