Radial Road 4

Radial Road 4, informally known as the R-4 Road, is a network of roads and bridges which comprise the fourth arterial road of Metro Manila in the Philippines. Spanning some, it connects the cities and municipalities of Makati, Manila, and Taguig in Metro Manila.
Previously, it ran along the Pasig Line, Kalayaan Avenue, M. Concepcion Avenue, Elisco Road, and Highway 2000 from Manila to Taytay, Rizal.
Initially conceived during the administration of Ferdinand Marcos, R-4's alignment was planned to be parallel to the Pasig River from C-2 in Manila to C-6 in Napindan, Taguig.
