Epifanio de los Santos Avenue

Epifanio de los Santos Avenue (EDSA), formerly known as Highway 54, is the main circumferential road and highway of Metro Manila in the Philippines. It is an important commuting artery between the northern and southern parts of the metropolitan area. EDSA is a partially-controlled access, mostly 10-lane divided highway (expressway) with interchanges along its length that eliminate the need for traffic lights, though traffic lights exist where there is insufficient space or funds for a complete interchange. EDSA handles around 225,000 cars per section on average every day.

EDSA forms a major portion of one of the circumferential roads in Metro Manila, C-4. It runs in a rough semicircle around Metropolitan Manila and, from the south, passes through the cities of Pasay, Makati, Mandaluyong, Quezon City, and Caloocan. Its southern endpoint is at a roundabout near the SM Mall of Asia in Pasay and its northern terminus is at Monumento, a monument to Andrés Bonifacio, in Caloocan. When the avenue was constructed during the presidency of Manuel L. Quezon, it was named Junio 19 (June 19), after the birthday of national hero José Rizal. It was later renamed Highway 54, and under Republic Act in 1959 was further renamed in honor of Epifanio de los Santos, a noted Filipino historian.

The Metro Rail Transit (MRT), Line 3 of the metropolis' railway system, runs along most of EDSA, from Taft Avenue in the south to North Avenue near the SM City North Edsa Mall in northern EDSA. Future expansion of the MRT will extend it all the way to Monumento.

EDSA also figures prominently in the recent history of the Philippines for being the site of two peaceful demonstrations that toppled the administration of two Filipino presidents—the People Power Revolution of 1986 against Ferdinand Marcos and the EDSA Revolution of 2001 against Joseph Estrada.

Traffic management

Being the most important artery of the metropolis, EDSA handles a significant volume of the traffic that flows through the cities of Metro Manila. An average of 2.34 million vehicles go through EDSA every day.

The lead agency that manages the flow of traffic along EDSA is the Metropolitan Manila Development Authority (MMDA), an agency that is under the Office of the President and is advised by the Metro Manila Mayors League. One of the MMDA's traffic management schemes that is in effect on EDSA, among other major thoroughfares, is the Unified Vehicular Volume Reduction Program, commonly known as the Number Coding Scheme. Many people observe that the cause of traffic jams on EDSA are erring bus and jeepney drivers especially as a multitude of the public utility vehicles they drive are unlicensed or "colorum". Subsequently, buses have been the target of other traffic management programs, like the MMDA's Organized Bus Route Program.
