Rep. Campos urges feasibility study for innovative infrastructure solution
AS traffic congestion and flood risks continue to plague Metro Manila, Makati City Rep. Luis Campos Jr. is proposing an ambitious infrastructure initiative: a dual-purpose road tunnel and flood control channel beneath Epifanio de los Santos Avenue (EDSA).
In House Resolution No. 2130, Campos calls on the National Economic and Development Authority (NEDA), in coordination with the Department of Public Works and Highways (DPWH), the Metro Manila Development Authority (MMDA), and the National Irrigation Administration (NIA), to conduct a comprehensive feasibility study for the project.
“EDSA is overstretched and flood-prone. We need bold, long-term infrastructure solutions that address both traffic congestion and climate-driven flooding,” Campos said.
Stretching 23.8 kilometers, EDSA serves as the primary artery linking northern and southern Luzon.
It remains one of the most heavily traveled highways in the country, accommodating over 400,000 vehicles daily—far beyond its designed capacity of 288,000.
Meanwhile, EDSA’s low-lying areas are increasingly vulnerable to flooding, which disrupts mobility and inflicts economic damage during the rainy season.
“This isn’t just about solving today’s problems—it’s about future-proofing Metro Manila’s infrastructure in the face of rapid urbanization and harsh climate change,” Campos said.
As a potential model, Campos cited Malaysia’s SMART Tunnel in Kuala Lumpur, which functions as both a roadway and a stormwater diversion system. The tunnel automatically closes to traffic during heavy rainfall to allow floodwaters to pass through and is typically cleared and reopened within 48 hours.
The proposed EDSA tunnel, Campos said, could deliver multiple benefits, including:
Alleviating surface-level traffic congestion;
Mitigating urban flooding through efficient stormwater diversion; and
Supporting the reuse of stormwater for agricultural irrigation, in line with President Ferdinand Marcos Jr.’s broader agenda for sustainable water management.
If deemed feasible, the proposed EDSA tunnel could significantly reshape the future of mobility and flood mitigation in the National Capital Region.
In 2019, San Miguel Corporation (SMC)—one of the country’s largest toll road operators—proposed the construction of a 10-lane elevated steel expressway above EDSA.
