Good news for everyone. The new southern extension of BTS Sukhumvit Line is now open, allowing you to hop on and off for free for the first four months (until 15 April). The new line consists of eight stations and runs from the existing Samrong station to Kheha (National Housing Authority) station located in Samut Prakan province. They are Pu Chao, Chang Erawan, Royal Thai Naval Academy, Pak Nam, Srinagarindra, Phraek Sa, Sai Luat, and Kheha.
While details about tickets have not been officially announced yet, we've heard that the ride will cost no more than B65 for the whole extension after 16 April. Stay tuned for more updates!
