Ortigas Avenue

Ortigas Avenue is a 12.1 km (7.5 mi) highway connecting eastern Metro Manila and western Rizal in the Philippines. It is one of the busiest highways in Metro Manila, serving as the main thoroughfare of the metro's east–west corridor, catering mainly to traffic to and from Rizal.

The western terminus of the highway is at the boundary of San Juan and Quezon City. The highway then traverses through Ortigas Center and along the cities of Mandaluyong, Quezon City, and Pasig, followed by the municipality of Cainta, and finally ending in the municipality of Taytay. Its section from Dr. Sixto Antonio Avenue in Pasig to Felix Avenue in Cainta is also part of the Manila East Road.

The portion of Ortigas Avenue from EDSA–Ortigas Interchange, Quezon City to the Buli Bridge at the Pasig–Cainta boundary is designated as Radial Road 5 (R-5). The highway is also designated as National Route 60 (N60) and National Route 184 (N184) of the Philippine highway network, respectively.
