This list of roads in Metro Manila summarizes the major thoroughfares and the numbering system currently being implemented in Metro Manila, Philippines.
Metro Manila's major road network comprises six circumferential roads and ten radial roads connecting the cities of Caloocan, Las Piñas, Makati, Malabon, Mandaluyong, Manila, Marikina, Muntinlupa, Navotas, Parañaque, Pasay, Pasig, Quezon City, San Juan, Taguig, and Valenzuela, and the municipality of Pateros.
This list only covers roads that are listed on the Department of Public Works and Highways's Infrastructure Atlas, as well as the previous circumferential and radial road system prior to 2014, and other notable roads in the metro. These road classifications are defined as follows:
Both primary and secondary roads may be designated as bypass or diversion roads, which divert through traffic away from city or municipal business centers with affirmative feasibility studies, or roads that would connect or fill the gap between adjoining national roads.
Any roads not classified as national primary, national secondary, or national tertiary may be classified as follows:
Additional classifications are unclassified roads, road not yet given official classification, and private roads, roads that are maintained by private entities and may have access restrictions.
The first road numbering system in the Philippines was adapted in 1940 by the administration of President Manuel Quezon, and was very much similar to U.S. Highway numbering system. Portions of it are 70 roads labeled Highway 1 to Highway 60. Some parts of the numbering system are Admiral Dewey Boulevard (Highway 1), Calle Manila (Highway 50) and 19 de Junio (Highway 54).
In 1945, the Metropolitan Thoroughfare Plan was submitted by Quezon City planners Louis Croft and Antonio Kayanan which proposed the laying of 10 radial roads, which purposes in conveying traffic in and out of the city of Manila to the surrounding cities and provinces, and the completion of six Circumferential Roads, that will act as beltways of the city, forming altogether a web-like arterial road system. The Department of Public Works and Highways (DPWH) is the government agency that deals with these projects.
The road numbering for radial roads are R-1 up to R-10. The radial roads never intersect one another and they do not intersect circumferential roads twice; hence they continue straight routes leading out from the city of Manila to the provinces. The numbering is arranged in a counter-clockwise pattern, wherein the southernmost is R-1 and the northernmost is R-10. Circumferential roads are numbered C-1 to C-6, the innermost beltway is C-1, while the outermost is C-6.
There are ten 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, numbered in a counter clockwise pattern. All radial roads starts at Kilometer Zero, demarked by a across from the Rizal Monument in Rizal Park along Roxas Boulevard.
There are six circumferential roads around the City of Manila that acts as beltways for the city. The first two runs inside the City of Manila, while the next three runs outside the City of Manila. All are beltways around Intramuros.
The radial and circumferential road numbers are being supplanted by a new highway number system, which the Department of Public Works and Highways have laid out in 2014. The new system classifies the national roads or highways as national primary roads, national secondary roads, and national tertiary roads. Primary national roads are numbered with one to two-digit numbers. Secondary national roads are assigned three-digit numbers, with the first digit being the number of the principal national road of the region. Secondary national roads around Manila mostly connect to N1 and are numbered with 100-series numbers.
Expressways are assigned with numbers with an E prefix to avoid confusion with numbered national roads. The network consists of controlled-access highways and limited-access roads, with crossing traffic limited to overpasses, underpasses, and interchanges. Some existing expressways serving Metro Manila also form part of the latter's arterial road network (see the list above).
Many other streets in the metropolis are considered major roads. Only Dr. Arcadio Santos Avenue (Sucat Road or N63) is designated a primary national road that is not part of the arterial road system. Roads with 3-number designations are secondary national roads.
This list only covers roads that are listed as National Primary, National Secondary, or National Tertiary Roads on the Department of Public Works and Highways's Infrastructure Atlas or are considered as notable roads for the specific city or municipality.
Mabuhay Lanes are a network of roads in Metro Manila designated as priority traffic corridors, serving as alternate routes to the existing radial and circumferential road system of Metro Manila.
It was established in 2010 by the Metropolitan Manila Development Authority (MMDA) under chairman Francis Tolentino and Metro Manila Council through the issuance of MMDA Resolution No. 10-26 series of 2010, which designated six north-south routes parallel to the heavily congested EDSA as Christmas Lanes and Mabuhay Lanes. These routes were eventually expanded to 17 routes and retained permanently. As priority corridors, the segments of all roads designated as Mabuhay Lanes or Christmas Lanes are marked as no parking zones, no street vending zones, and no Christmas caroling zones. These segments are also subject to routine MMDA patrols that conduct vehicle impoundment via towing and clearing of other road and sidewalk obstacles.
