Bangkok's transport committee approved BTS upgrades to the Chit Lom elevated walkway linking Gaysorn Plaza, Hyatt Erawan and Amarin Plaza: non-slip flooring, roofs, lighting and more CCTV. Also: the Green and Gold line assets and debts are being transferred to MRT authority (MRTA), and a unified fare system is set to start 1 January 2027 with a fare-reduction policy and card-reader readiness checks. For shops and offices near Chit Lom, expect walkway works and possible foot-traffic disruption; for transport-dependent businesses, a single fare card is coming in early 2027.
