Dr. Santos Avenue

The avenue was originally called Sucat Road and was named for the barrio in Muntinlupa and its railway station to which it led. Its present name is taken from Dr. Arcadio Santos, a native of Parañaque who was the governor of Rizal from 1920 to 1922 when the then-municipality was still part of the province.[4]

In September 2013, a bill was authored in the Philippine House of Representatives to rename Dr. Santos Avenue to President Cory Aquino Avenue. This bill authored by Rep. Eric Olivarez is still pending in the Committee on Public Works and Highways as of October 2013.[5]

The avenue will soon be served by the Manila Light Rail Transit Line 1 (via Dr. Santos station) to be constructed in the vicinity of C-5 Extension.

Dr. Santos Avenue runs through barangays San Dionisio, San Isidro, San Antonio, and BF Homes in Parañaque and Sucat in Muntinlupa. It begins in San Dionisio as the continuation of Ninoy Aquino Avenue south of Ninoy Aquino International Airport Terminal 1, where the road narrows to three lanes from four. The road continues due east to cross C-5 Road Extension, N. Lopez Avenue, President's Avenue, and the South Luzon Expressway (Sucat Interchange). It terminates at the East Service Road, which runs parallel to the expressway next to the interchange. It then continues east towards the Sucat railway station as Meralco Road.

The eastern section of the avenue is known as the location of two of Metro Manila's biggest cemeteries, such as Manila Memorial Park and Loyola Memorial Park. Notable places located along the road also include two SM shopping malls such as SM City Sucat and SM City BF Parañaque, Amvel Business Park, which houses the El Shaddai church, and the Santana Grove strip mall.

Intersections are numbered by kilometer post, with Rizal Park in Manila designated as kilometer zero.
