Guicam bridge on track to transform transport in southwestern Mindanao

Construction of the Guicam Bridge in Zamboanga Sibugay is nearing completion, with the Department of Public Works and Highways (DPWH) reporting nearly 88 percent progress as of July 2025.

The %u20B11.155-billion project is a key component of the Improving Growth Corridors in Mindanao Road Sector Project (IGCMRSP), which is financed by the Asian Development Bank (ADB) and implemented under the national government's “Build Better More” infrastructure initiative. It is designed to connect Olutanga Island to the mainland via the municipality of Alicia, enhancing mobility and economic integration across the Zamboanga Peninsula.

Senior Undersecretary Emil K. Sadain, who oversees the DPWH’s flagship infrastructure projects, inspected the site on July 4 and instructed the contractor—Grace Construction Corporation in joint venture with Tianyuan Construction Group Corporation—to accelerate the ongoing girder installation and concrete slab works. The inspection team included project supervisors and technical consultants from DPWH and Renardet S.A. Consulting Engineers.

“Once completed, the bridge is expected to significantly reduce travel time, enhance regional logistics, and strengthen inter-island connectivity and access to essential services across southwestern Mindanao,” Sadain said. “This project will help improve the quality of life in the region and support inclusive growth.”

The Guicam Bridge will span 540.8 meters across the Canalizo Strait and consist of 12 spans supported by prestressed concrete girders. It will also include approach roads measuring 389.6 meters on the mainland side and 277.6 meters on the island side. The structure is designed with maritime navigation in mind, offering a clearance of 14.8 meters in height and 24 meters in width.

As of the latest update, all major foundation works have been completed, including 115 bored piles. Girder fabrication is also well advanced, with 40 of 48 girders finished and 36 already stressed and grouted. The bridge’s first span has its deck slab in place, and both embankment and pavement works are underway on the mainland and island approaches.

Officials said the bridge’s completion, targeted by early 2026, will provide critical infrastructure to link communities, reduce transportation costs, and promote trade, tourism, and public service delivery in the region.
