The Makati Intra-city Subway or (MkTr) is an under-construction underground rapid transit line to be located in Makati, Metro Manila, that will link establishments across the city's business district. It will be built under a public-private partnership program between the Makati City Government and a private consortium, led by Philippine Infradev Holdings. Proponents of the subway are expected to begin construction by December 2018, and Makati Mayor Abigail Binay projects completion by 2025. The subway will cost $2.5 billion (or ₱125 billion) and is expected to accommodate 700,000 passengers daily. It will also have nine stations, with connections to the existing MRT Line 3, Pasig River Ferry Service, and the under-construction Metro Manila Subway.
