The Patapat Viaduct is a viaduct at the municipality of Pagudpud, Ilocos Norte, a coastal resort town on the northernmost tip of Luzon Island in the Philippines.
The bridge is elevated 31 meters over sea level. It is a concrete coastal bridge 1.3 km long and connects the Maharlika Highway from Laoag, Ilocos Norte to the Cagayan Valley Region. The viaduct was constructed by Hanil Development Co. Ltd. under the overall management of DPWH-PMO-PJHK and was completed and opened to traffic in October 1986. It rises along the town’s coastal mountains, which is the starting point of the Cordillera Mountain Range that snakes through Northern Luzon. It is the 4th longest bridge in the Philippines.
This viaduct was constructed to solve the problem of landslides in the area which have caused so many vehicular accidents in the past. Footed on the rocky seashore just several meters from the mountain side it gives motorists a spectacular view of Pasaleng Bay.
The bridge has become as one of the tourist attraction in Pagudpud. The inviting scenery often getting off the commuters and motorists from their cars to capture some pictures.
