Radial Road 1


Radial Road 1, more commonly referred to as R-1, is a long network of roads and bridges that altogether form the first arterial road of Manila in the Philippines. The road runs north-south linking the City of Manila to the Metro Manila cities of Pasay, Parañaque and Las Piñas, down to Bacoor, Imus, Kawit, Noveleta, General Trias, Tanza, and Naic in the province of Cavite.

The road consists of the following segments from north to south:
