The Candaba Viaduct (also known as Pulilan–Apalit Bridge and Candaba Pampanga Viaduct) is a 5-kilometer (3.1 mi) viaduct carrying the North Luzon Expressway (NLEX) across the Candaba Swamp in the provinces of Pampanga and Bulacan, Philippines consisting of six lanes (three northbound and three southbound). It was the longest bridge in the Philippines upon its opening in 1976, surpassed in October 5, 2021 by the 8.9 km Cebu–Cordova Link Expressway (CCLEX) upon its inauguration making the viaduct now the second longest bridge in the country. The viaduct was designed by Aas-Jakobsen and built by Construction Development Corporation of the Philippines (CDCP, later renamed to Philippine National Construction Corporation) as part of construction of the whole NLEX.[2][1] [3]
Overlooking Mount Arayat in the east and Zambales Mountains in the west, the viaduct is raised over Candaba Swamp, which keeps the highway open to traffic, even when the swamp gets flooded during the rainy or monsoon season.[4] Lighting, emergency callboxes and CCTVs along the viaduct are powered by solar panels due to the problem of installing power lines within the viaduct.[5]
