The rebuilding of the NLEX is one of the biggest infrastructure projects undertaken in the Philippines over the last ten years. It involved the rehabilitation, expansion and modernization of the 84-kilometer North Luzon Expressway.

The existing 295 lane kilometers from Balintawak to Sta. Ines were upgraded, and an additional 138 lane kilometers from Balintawak to Sta. Rita, Bulacan were constructed. Additional lanes were built in the mainline with eight lanes in both directions from Balintawak to Burol, and six lanes from Burol to Sta. Rita. Furthermore, major rehabilitation works were done on the four lanes from Sta. Rita to Balem and the two lanes from Balem to Sta. Ines.

All the existing 91 toll booths were demolished to give way to 145 new toll booths. Four toll plazas were constructed and expanded in Balintawak, Bocaue, Tabang and Dau while 26 permanent exits were widened. The Novaliches flyover and the Dau interchange were added to ease up traffic on both ends of the expressway.
