EDSA station was constructed as part of the original alignment of Metrorail (present-day LRT-1), beginning in September 1981, after an economic recession delayed the project’s initial timeline.

[2] The station was opened to the public on December 1, 1984, as part of LRT’s initial southern section, known as the Taft Line, which was the first segment to become operational.

[2][3] It existed long before the LRT-1 was extended northward along EDSA through Caloocan and Quezon City, adding two stations there as part of the North Extension, which opened in 2010.

[8] The project consists of the expansion of the structure through the third floor of the adjacent Liana's Supermarket & Department Store and constructing a bridge to connect nearby areas.

The expansion also features new comfort rooms, a wheelchair ramp, LED lighting setups, interior paint jobs, and floor finishes.
