East Service Road in San Martin de Porres Bicutan shopping mall on East Service Road The
South Luzon Expressway and elevated
Skyway run for approximately along San Martin de Porres's western boundary. The main access road into the village and its principal north–south corridor is a
frontage road east of the expressway which is a national tertiary road known simply as East Service Road. The village's only road link with
Don Bosco and the rest of Parañaque is the Bicutan crossing at the three-level Bicutan Interchange serving as the junction between the South Luzon Expressway,
Doña Soledad Avenue and General Santos Avenue, and between the Skyway and Doña Soledad Avenue. Its main east–west access road starts from this interchange as a continuation of Doña Soledad Avenue into Central and Lower Bicutan towards the Pateros-Alabang Road (Manuel L. Quezon Street) and
C-6 Road on the shores of
Laguna de Bay. At the village's north end separating it from Western Bicutan and Arca South is Cucumber Road which gives access to the San Martin de Porres Barangay Hall and which is also linked to FTI Avenue and Tanyag Avenue in
South Signal Village at its eastern terminus. This portion of San Martin de Porres is a predominantly slum area with 600 families living there when a fire broke out in August 2015. Several Sitios on its eastern end, mainly Sitio Sampalocan and Sitio GSIS, could only be accessed by cramped one lane roads connecting to Rajah Sumakwel Street, Upper Bicutan, Taguig City, making them technical enclaves. A tricycle route operated by SUBTODAI connects these sitios to the DOST Terminal along East Service Road via Upper Bicutan, Taguig's Raja Trinanes and Rajah Sumakwel streets, and Central Bicutan, Taguig's A. Bonifacio Avenue. Within the gated community of United Hills Village (UPS1) south of Cucumber Road linked to the East Service Road at its west end is its main street, Narra Street, which leads to the San Martin de Porres Parish Church. Just south of United Hills is Marian Park and UPS2 which is traversed by Marian Road where the Dr. Arcadio Santos National High School is situated. Its central section near General Santos Avenue is dominated by the Bicutan Market and
Walter Mart Bicutan shopping mall. The village's southern portion is a narrow strip of warehouses fronting the East Service Road. The Bicol Commuter and
Metro South Commuter lines of the
Philippine National Railways run along the median between East Service Road and South Luzon Expressway; the
North–South Commuter Railway is under construction above these old lines. San Martin de Porres is served by the
Bicutan railway station situated near the Bicutan Interchange where a long footbridge also connects this village across the South Luzon Expressway to Don Bosco by the SM City Bicutan mall. ==References==
