Metro Manila has a very extensive roadway system connecting the cities and municipalities of the metropolis and its surrounding provinces. The major roadways are the ten radial roads, braching from the capital city of Manila, and the five circumferential roads, which form semicircles around the city of Manila. It should be known that the Radial and Circumferential roads are not 'existing roads', per segment, but are labels that connect existing roads, so that they serve as guides. Some of the roads in Metro Manila are not yet paid to the government.
List of Roads
The ten (10) radial roads that serves the purpose of conveying traffic in and out of the city of Manila to the surrounding cities of the metropolis, and to the provinces.
The five circumferential roads are arranged in concentric semicircles in and around Metro Manila, so as to get traffic from the northern part to the southern part as easily as possible. There is also a new circumferential road, the C-6, which is under construction. The routes are described from north to south (clockwise).
