On May 24, 2021, Urban Avenue from Amorsolo Street was closed  to traffic to give way to the construction of the Makati Subway Project.

The Makati City government and Philippine Infradev Holdings Inc. sealed a joint venture agreement for the $3.5 billion Makati City Subway.

The Subway will have 10 underground stations with at least 30 entrances linked to key destinations around the city namely, Central Business District at the corner of Ayala and Sen. Gil Puyat Avenues, Circuit City, Makati City Hall, University of Makati and Ospital ng Makati. The stations will also have connections to the existing MRT Line 3, the Pasig River Ferry Service, and the under-construction Metro Manila Subway. Passenger capacity is expected to be at 700,000 daily. It is also mentioned that there will be 12 air-conditioned trains in the first year of operation with intervals of 3 to 6 minutes that will operate 18 hours everyday.

On December 12, 2018, the preparatory work, including soil testing and feasibility studies of the proposed locations for the subway line’s stations, officially began, followed by a ceremonial drilling ceremony in front of the Makati City Hall, near the site of one of the proposed stations of the subway. The signing of the memorandum of understanding between the Makati city government and a consortium consisting of Philippine Infradev and Chinese firms Greenland Holdings Group, Jiangsu Provincial Construction Group Co. Ltd., Holdings Ltd. and China Harbour Engineering Company Ltd was also held.

Furthermore, the Makati Subway will be very beneficial because the commutes will be faster and easier. And if the commutes are faster, there will be an increase in work productivity and opportunities for businesses. There will also be an increase in profits for real estate investors. And finally, there will be a reduction in air pollution.

As for the fares and ticketing of the subway, the upcoming line will use a distance-based fare structure and will be charged 20% to 25% higher than the fares of Line 1 and Line 3. A 25 % premium will bring the subway’s rate to about ₱38 for 10 stops
