The roads of Metro Manila are built around the [[Manila|City of Manila]]. Roads are classified as local, national or subdivision roads. There are ten radial roads branching out from the city. Also there are five circumferential roads forming a series of concentric semi-circular arcs around Manila. The circumferential and radial roads are systems of interconnected roads, bridges and highways. A problem with the circumferential roads are the missing road links. These are the roads that are not yet constructed to give way for development due to Metro Manila's rapid urbanization. The metropolis is resolving this problem through the completion of missing road links or through the construction of connector roads.

The radial and circumferential road system are being supplanted by a new numbered highway system implemented by the [[Department of Public Works and Highways]], and new signage are being placed with its implementation. Expressways are being assigned numbers with the E prefix. National roads are assigned 1 to 3 digit numbers, except for those classified as tertiary national roads.

An important circumferential road is the [[Circumferential Road 4]], with the [[EDSA|Epifanio de los Santos Avenue]] as its major component. It traverses the cities of [[Pasay]], [[Makati]], [[Mandaluyong]], [[Quezon City]] and [[Caloocan]]. [[Manila Metro Rail Transit System Line 3|Line 3]] follows the alignment of EDSA, from [[Taft Avenue]] in [[Pasay]] up to [[TriNoma]], terminating before it reaches [[Caloocan]]. [[Circumferential Road 5]] serves the people near the regional limits of Metro Manila and also serves as an alternate route for Circumferential Road 4.

Prominent radial roads include the Radial Road 1, composed of [[Roxas Boulevard]] and the [[Manila–Cavite Expressway]] (Coastal Road) that connects Metro Manila to [[Cavite]], Radial Road 3 or the [[South Luzon Expressway]] that connects Metro Manila to [[Laguna (province)|Laguna]], Radial Road 6, composed of [[Aurora Boulevard]] and [[Marikina–Infanta Highway|Marcos Highway]] that runs up to [[Rizal (province)|Rizal]] and Radial Road 8 or the [[North Luzon Expressway]] that serves as the gateway to the north.

The [[Skyway (Metro Manila)|Skyway]] serves as the region's main [[Controlled-access highway|expressway]], directly connecting the North Luzon Expressway and the South Luzon Expressway. It also enables access to Ninoy Aquino International Airport via the [[NAIA Expressway]] (NAIAX). The Skyway is the first fully grade-separated highway in the [[Philippines]] and one of the longest elevated highways in the world with a total length of approximately {{convert|42.79|km|mi|sp=us}}. Other expressways such as the Manila–Cavite Expressway and [[Muntinlupa–Cavite Expressway]] also connect Metro Manila to its surrounding areas.

The development of roads, highways and expressways are based on the [[Metro Manila Dream Plan]]. Ongoing projects in the dream plan include the rehabilitation of EDSA, [[CAVITEX–C-5 Link]], [[NLEX Connector]], and the construction of the missing road links for the circumferential roads.
