The Metro Manila Subway Project’s Contract Package 102 achieved a tunnel breakthrough on September 14, 2026, at Quezon Avenue Station in Quezon City. The breakthrough connected a roughly 1.12-kilometer southbound tunnel from North Avenue Station to Quezon Avenue Station. This is described as the first tunnel breakthrough for the subway project and marks progress toward connecting communities across Metro Manila. Once the full line is operational, the project is expected to cut travel time between Valenzuela City and NAIA Terminal 3 from over 90 minutes to about 41 minutes. The milestone was a construction-site event, and the provided information gives no public attendance, registration, or visitor details; it is not presented as an event for spectators. The completed tunnel section is part of a 3.1-kilometer package covering Quezon Avenue Station, East Avenue Station, and their connecting tunnels.
Background
The Metro Manila Subway is planned as a 33.1-kilometer line with 17 stations, connecting Valenzuela City to NAIA Terminal 3 in Pasay City. At Quezon Avenue Station, the diaphragm wall was built with fiberglass-reinforced polymer bars in the breakthrough area so the tunnel boring machine could pass through without the cutterhead encountering conventional steel reinforcement. This cuttable reinforcement approach is commonly used to facilitate TBM passage through station walls.
