The major thoroughfares of the metropolis are classified as either a circumferential road or a radial road. But just what is a circumferential and a radial road by the way?
In layman's terms, circumferential roads are those roads that are meant to traverse the whole or a big portion of the metropolis. Radial roads, meanwhile, are those secondary roads also traverse multiple parts of the metropolis but the area covered by these roads are smaller, and they are also meant to connect circumferential roads to each other.
Another thing one could note upon seeing Manila's road network is that a circumferential road or a radial road bears several names because it traverses several areas. It's the prerogative of whoever is seated on the local government of the area, through a local ordinance, to either preserve the existing name of the road or replace it with a name that would be relevant to the area in which the road cuts through.
I. C-1 : Padre Burgos St., Ayala Boulevard, P. Casal St. and C.M. Recto Avenue
Location: City of Manila
C-1 is indeed the first circumferential road network to exist,as characterized by the infrastructure surrounding it like the old Senate Building, Rizal Park, and Intramuros. Compared to other circumferential road networks, C-1 is relatively shorter. The C-1 road network lets one traverse the Southwestern and Western areas of the capital.
II. C-2 : Pres. Quirino Avenue, Nagtahan, A.H. Lacson St. (Gov. Forbes) and Tayuman
Location: City of Manila
Commercial/residential fixtures characterize the area in which this road cuts through. It also provides a mix of other infrastructures such as schools, government offices (Malacanang is situated along this area), and oil depots of the region. The end of Tayuman, on the other hand, leads one to the major ports of the capital. The C-2 road network lets one traverse the Southern and Northwestern areas of the capital.
III. C-3 : Sen. Gil Puyat Avenue, South Avenue, Trabajo St., Coronado St., San Francisco St., 9 de Pebrero St., Shaw Boulevard., F. Manalo St., San Juan Bridge, G. Araneta Avenue, Sgt. Rivera St., and 5th Avenue
Location: Makati City, Mandaluyong City, San Juan, Quezon City and Navotas
This particular road network is very useful, especially for those frequenting the Port Area This network provides a quick way to get from Makati to Mandaluyong to San Juan. Going further straight ahead in Araneta Avenue leads one to Sgt. Rivera and to the Manila North Harbor in Navotas City. The C-3 road network lets one traverse the Southern and North/Northwestern parts of the capital.
The MMDA is currently thinking of other ways to solve the problem, to the point that chairman Bayani Fernando is thinking of ramming down the gates of exclusive villages so that the general public can use their roads. The Supreme Court has already decided on this controversial issue during the term of former chairman Jejomar Binay, so I don't think the current chairman can do anything except beat his chest. Besides, he might disenfranchise several influential families who live in these exclusive villages and get into trouble with the supporters of his supporter, President GMA.
IV. C-4 : Epifanio delos Santos Ave. (EDSA)
Location: Caloocan City, Quezon City, Pasig City, Mandaluyong City,
Makati City, Paranaque City, City of Manila
One ain't Filipino unless he knew of EDSA. From its daily traffic jams and three bloodless revolutions, EDSA (Highway 54 to some folks) is perhaps the best-known circumferential road. Primarily designed to ease up vehicular volume in the areas it cuts through, it has ably performed its purpose. This network also is the well-funded of them all, with its share of fly-overs and underpasses, and of course, the MRT. It's just straight ahead in here, no other names to remember, unlike the aforementioned networks. EDSA lets one cut through the whole metropolis. Almost every major road in the metropolis leads to EDSA.
V. C-5 : E. Rodriguez Avenue, B. Serrano Avenue (Santolan), Katipunan Road, Luzon Avenue, Republic Avenue
Location: Fairview, Loyola Heights, Libis and Bagumbayan in Quezon City, Pasig City, Taguig, Makati City
Up to now it has to be determined if this particular road network is 100% complete. Right-of-way problems (squatters, factories and other establishments) and other political problems led to the shelving of this project maybe twice or thrice. Originally a brainchild of former President Marcos, he initially envisioned a road that would literally cut through the metropolis. Literally in the sense that he wants this road to cut through the hilly portions of Taguig, Pasig and Makati. A wider Luzon Avenue has yet to materialize and Republic Avenue road area in Fairview remained a haven for informal settlers. The C-5 road lets one traverse the Northern, Eastern and Southern parts of the metropolis.
VI. C-6 : (ongoing)
Location: Bulacan, Rizal provinces, Marikina City, Antipolo City, Pasig City, Taytay, Rizal, Taguig, Paranaque City
The C-6 road cuts through the Northern suburban part of the Metropolis , particularly the provinces of Bulacan and Rizal. Potential right of way problems and terrain problems are some issues that keep the project from being in full swing. But when finished, this would be a great relief especially for those residing in the outskirts of the metropolis.
I. R-1 : Roxas Boulevard and Manila-Cavite Road (Aguinaldo Highway)
The historic Roxas Boulevard (Dewey Boulevard to some) has been lengthened to include the Manila-Cavite Road, otherwise known as Aguinaldo Highway. Nowadays, Cavite has traded its farming lands to commercial and residential development, while the cool city of Tagaytay is just kilometers away.
II. R-2 : Taft Avenue Road
Numerous schools and universities line up Taft Avenue. Some government offices also like the National Bureau of Investigation, Phil. Gen. Hospital and the Supreme Court are situated in this area. Taft Avenue is now also a major thoroughfare that leads to fantastic night spots, specifically in the Malate Area.
III. R-3 : Manila South Expressway
From Alabang, Muntinlupa, to Los Banos, Laguna, it's only the Manila South Expressway that could take you there. Now has an elevated portion called the Skyway if one's in a hurry.
IV. R-4 : Pasig Line and Kalayaan Avenue
The ambitious but essential R-4 road network has been slightly deviated to give way to the Pasig Expressway (PASEX) project. Under the proposal, the 15 km expressway runs west from Makati area and then north to Ortigas Avenue. It promises to provide a link to residential and commercial areas of Pasig and Makati.
V. R-5 : V. Mapa St., P. Sanchez, Shaw Boulevard, Pasig Boulevard
From Manila, this is a proven network if one wishes to travel towards the Eastern portions of the metropolis, particularly Pasig ang Pateros.
VI. R-6 : Legarda, Magsaysay Boulevard, Aurora Boulevard, Marcos Highway and Sumulong Highway
Another road network that traverses the district's University Belt Area. It also cuts through historical districts such as San Juan and Sta. Mesa. It cuts through five cities, namely, Manila, Quezon City, San Juan, Marikina and Antipolo. This serves as a link to the eastern and the western sectors of the capital.
VII. R-7 : Lerma, España, Quezon Avenue and Commonwealth Avenue
Another important road network in the metropolis. From the University Belt area, and then straight ahead to Espana (one of the oldest roads to exist), and then going straight ahead leads one to the northeastern part of the capital, particularly Fairview and Novaliches, both in Quezon City. This network also serves as a major link between the city of Manila and Quezon City.
VIII. R-8 : Quezon Boulevard, Andalucia, Dimasalang, A. Bonifacio Avenue and Quirino Highway
Don't be confused with the name Quezon Blvd. This particular Quezon Blvd. pertains to the one in Quiapo, Manila, passing by the Quiapo Church. Travelling straight ahead brings one to Andalucia St. Afterwards, by making a slight right, Dimasalang St. is now being traversed. Going straight ahead leads one to the North Cemetery / Chinese General Hospital area and A. Bonifacio St. Going further leads one to Quirino Highway (Novaliches-Ipo road), which is the first route to the town of Novaliches in Quezon City.
IX. R-9 : J. Rizal Avenue and McArthur Highway
Rizal Avenue or simply Avenida to some folks, this is the proven path that leads to the downtown areas of the metropolis, particularly Sta. Cruz, Binondo, Quiapo and Divisoria, all in the city of Manila, whereas taking the other side of this road leads to the Malabon, Valenzuela and Bulacan areas.
X. R-10 : Radial Road 10
Coming from Roxas Blvd and then straight ahead leads one to this road. This particular road network is meant to cut through the northwestern part of the metropolis, particularly Malabon and Navotas area. This is also another route if one wishes to go to the ports of the capital.
