Ho Chi Minh City–based Masterise Group has submitted a proposal to the Ho Chi Minh City People’s Committee to develop Metro Line 3 under a public–private partnership (PPP) model using a build–transfer (BT) contract. The company seeks approval to prepare an investment plan and has committed to self-financing the preparation of proposal dossiers, bearing all associated costs and risks if the project is not approved.

The proposed Metro Line 3 will span 45.8 km, connecting An Ha in the former Binh Chanh District to the Hiep Binh Phuoc depot in the former Thu Duc City. The route will run along key transport corridors including An Ha, Le Minh Xuan, Tan Kien Station, National Highway 1, Kinh Duong Vuong, Hong Bang, Hung Vuong, Cong Hoa Roundabout, Nguyen Thi Minh Khai, Xo Viet Nghe Tinh, and National Highway 13. Land acquisition for the line will be undertaken in a single phase, and total investment will be finalized after design completion.

Masterise stated that the PPP structure aligns with Vietnam’s Law on Public–Private Partnership Investment and supports Resolution 68 of the Politburo on private economic development. The model is expected to mobilize private capital, leverage technical expertise, reduce the financial burden on the state, and accelerate project delivery. The city’s Department of Finance, along with relevant agencies, has been tasked with reviewing the proposal before October 24, 2025.

In addition to Metro Line 3, Masterise Group has previously proposed major infrastructure projects in Ho Chi Minh City, including the Can Gio Bridge, Phu My 2 Bridge, and an expressway linking Ho Tram with Long Thanh International Airport.
