Ben Thanh – Suoi Tien Metro Line 1 is the pioneering urban railway project that marked a major milestone in the development of public transportation in Ho Chi Minh City. With a total length of 19.7 km, the line connects Ben Thanh Station in District 1 to Suoi Tien Station through 14 stations, including 3 underground stations and 11 elevated stations. The route consists of a 2.6 km underground section from Ben Thanh Station to Ba Son Station and a 17.1 km elevated section from Van Thanh Station to Suoi Tien Station.
