The MIMAROPA Regional Project Monitoring Committee (RPMC) conducted an emergency field validation on the status of Lumintao bridge in Calintaan, Occidental Mindoro, which was damaged by monsoon rains and typhoon Domeng.
The massive and high discharge of water flow caused the misalignment of piers 4 and 4 of the bridge.
On June 19, 2018, it was closed to all vehicles, only pedestrians and motorcycle carrying goods were allowed to pass. On June 30, 2018, light vehicles were allowed to cross the bridge.
During the field visit on July 9, 2018, the team observed that maintenance engineers of the Department of Public Works and Highways (DPWH) provided steel piles and beams at pier 3 to provide support and prevent the collapse of the bridge.
DPWH engineers are preparing pier 3 for the installation of gabion mattress. According to Celestino Aroc III, foreman, they are working 24 hours in shifts to fast-track the laying of gabion mattresses in all of the piers to protect them from further damage during high river water discharges.
Moreover, Nelson Rosario, foreman, said that the on-going works temporarily secured the bridge to prevent further damage due to high river water discharges.
With the temporary repairs by DPWH engineers, the bridge is now passable to all types of vehicle, with maximum load limit set at five (5) tons. DPWH Engr. Danilo S. Miniz said that replacement of Lumintao bridge will be funded in 2019. A validation of the MIMAROPA Regional Development Council’s endorsed DPWH 2019 Annual Investment Program, revealed a total funding of P300 million proposed for the bridge replacement.
The Lumintao bridge serves as a critical infrastructure linking the towns of Rizal, San Jose, and Magsaysay to the capital town of Mamburao. With the monsoon season barely starting, the remedial measures being implemented in Lumintao may not hold until the 2019 funding is approved and released.
The immediate reconstruction/replacement of the bridge is recommended. The DPWH should explore the possibility of implementing the project within the year, according to the RPMC.
