Residents of Manila better avoid passing through the Nagtahan area for the time being. The Metropolitan Manila Development Authority (MMDA) announced that the Nagtahan Flyover has been off-limits to trucks starting last October 1, 2021. But it's not just trucks that are affected. The agency adds that only one lane of the structure will be accessible to motorists driving light vehicles for the time being.

The reason for the closure is this: the Department of Public Works and Highways (DPWH) is working to upgrade the Nagtahan Flyover. And they're not working on the pavement; they're working on strengthening the bridge to withstand seismic events like earthquakes and eruptions.

Older bridges and flyovers were constructed using standards (e.g. older AASHTO standards) that have since been outdated by the learnings from recent seismic events worldwide. To meet with newer DPWH Seismic Design Specification, the agency will undertake the removal and replacement of Nagtahan Flyover’s existing steel casing, provide additional reinforcing steel and protective coating to its piers, and restore affected pavement and sidewalk. However, additional funding will be required for the final Phase 2, which will cover the remaining 6 out of its 14 piers and a lighting system on the flyover.

The Department of Public Works and Highways (DPWH) will be handling the repair and rehabilitation works on the Nagtahan Flyover. According to DPWH Secretary Mark Villar, the agency was allocated PHP 50 million for Phase 1 of the Nagtahan Flyover Strengthening.

According to the MMDA, repair and rehabilitation of the Nagtahan Flyover will be done in several segments. Segment 1 and 2, the Northbound section (R. Magsaysay to G. Tuazon) will be finished within two months. Afterward, Segment 3 or the Southbound (G. Tuazon to R. Magsaysay Area) within 1.5 months. Segment 4 and 5 Northbound (EARIST to R. Magsaysay Blvd. area) within 2 months. Lastly, Segment 6 Southbound (R. Magsaysay to EARIST area) within another 1.5 months. Overall, the MMDA expects repairs to be completed by April 2022.

As an alternative route, vehicles going north are advised to take Osmeña Highway, right to Quirino Avenue, left to Quirino Ave. Ext., left to U.N Ave., right to Romualdez St., left to Ayala Blvd, and Roxas Blvd. to their destination. Meanwhile, soundbound vehicles may take A. Bonifacio Ave., right to C3, R-10, to their destination.
