Metro Rail Transit Line 4 to Connect Rizal to EDSA Ortigas, Passing Through Ortigas Avenue Extension.

Traffic along Ortigas Avenue and Ortigas Avenue Extension has long been one of the biggest challenges for commuters and motorists traveling between Metro Manila and Rizal Province.

Soon, a major infrastructure project is set to change that: the Metro Rail Transit Line 4 (MRT-4).

What is MRT-4?

The MRT-4 is a planned 12.7-kilometer elevated heavy rail transit line designed to connect EDSA–Ortigas in Mandaluyong City to Taytay, Rizal.

It will run along the busy Ortigas Avenue corridor, passing through key business districts, residential communities, and commercial hubs in Pasig City, Cainta, and Taytay.
