The Manila–Cavite Expressway, signed as E3 of the Philippine expressway network and R-1 of Metro Manila's arterial road network, is a 14-kilometer-long controlled-access toll expressway linking Manila to the southern province of Cavite in the Philippines. At its north end, it feeds into and from Roxas Boulevard in the city of Parañaque in Metro Manila, also part of R-1. At the south end, it splits into two termini, both along the north coast in Kawit, Cavite. The first feeds into the intersection of Tirona Highway and Antero Soriano Highway. The second southern terminus is on the intersection of Tirona Highway, Antero Soriano Highway and Covelandia Road in Kawit, Cavite.
The expressway also functions as a utility corridor carrying various high voltage power lines and water pipelines across the densely populated areas of Parañaque and Las Piñas. The final section of the Dasmariñas–Las Piñas Transmission Line and its substation were placed beside the highway.
