The road's entire main section is designated as National Route 63 (N63), while its short, narrow spur section beneath Skyway's Sucat Exit is a component of National Route 144 (N144); both routes are part of the Philippine highway network. It also has an eastbound spur towards the West Service Road at Sucat Interchange, classified as an unnumbered national tertiary road.[1]
Etymology
Arcadio Santos, for whom the avenue is named
The avenue's present name is taken from Dr. Arcadio Santos, a native of Parañaque who was the sitting governor of Rizal when the road was opened in 1921, while the then-municipality was part of the province.[4][5] It is formerly and alternatively known as Sucat Road and was named for the barrio (now barangay) of the same name in Muntinlupa and its railway station to which it led. It is also alternatively known as Parañaque–Sucat Road, indicating its purpose of connecting the old Parañaque town proper, located by Manila Bay, with Sucat in Muntinlupa.
History
The avenue originated as a carabao trail that opened in 1921, overlooking salt farms and grass plains.[4] It was later paved with asphalt and initially featured two lanes.[6] Originally named Sucat Road and Parañaque–Sucat Road, it was later renamed Dr. Arcadio Santos Avenue.
In September 2013, a bill was filed in the Philippine House of Representatives to rename Dr. Santos Avenue to President Cory Aquino Avenue.[7] This bill, authored by Representative Eric Olivarez (Parañaque–1st), is still pending in the Committee on Public Works and Highways as of October 2013.[8]
Considered as the longest avenue in Parañaque, 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, continuing from Ninoy Aquino Avenue south of Ninoy Aquino International Airport Terminal 1, where the road narrows to three lanes from four. The road continues east to cross C-5 Road Extension, N. Lopez Avenue, President's Avenue, and the South Luzon Expressway (Sucat Interchange). Two namesake spurs branching from the avenue near Sucat Interchange carry southbound traffic to and from West Service Road, respectively. It terminates at the East Service Road, which runs parallel to the expressway next to the interchange, in Muntinlupa. It then continues east towards the Sucat railway station as Meralco Road.[1]
The eastern section of the avenue is known as the location of two of Metro Manila's biggest cemeteries, Manila Memorial Park and Loyola Memorial Park. Notable places located along the road also include SM City Sucat, SM City BF Parañaque, Amvel Business Park, which houses the El Shaddai church, and the Santana Grove strip mall.
