The expressway also serves as a major utility corridor, carrying various high voltage overhead power lines through densely populated areas where acquisition and designation of right of way or power line alignment and lands for their associated structures is impractical. A notable power line using the expressway's right of way for most or part of the route is the Hermosa–Duhat–Balintawak transmission line where it utilizes the alignment or right of way of North Luzon Tollway (NLT) or NLEX Main from San Fernando Exit in San Fernando, Pampanga to Harbor Link Interchange in Valenzuela, Metro Manila, with the power line also represents how close a motorist does to Metro Manila if going southbound and San Fernando if northbound.
The North Luzon Expressway was built in the 1960s as part of the government's program to develop areas adjacent to Metro Manila, with NLEX serving the north. The expressway was originally controlled by the Philippine National Construction Corporation (PNCC), until the expressway's operations and maintenance was transferred in February 10, 2005, to the NLEX Corporation, a subsidiary of Metro Pacific Investments Corporation (a former subsidiary of Lopez Holdings Corporation until November 2008). The expressway was expanded and rehabilitated from 2003 to February 2005, modernizing the road and its facilities.
The North Luzon Expressway's main segment, called the North Luzon Tollway (NLT) or NLEX Main, cuts northwards from Quezon City to the provinces in Central Luzon.
From Balintawak, the NLEX follows a straight north route, with sections lined by billboards. Two service roads run on either sides of the expressway from Balintawak to Barangay Lias, Marilao, albeit discontinuously and one service road on the west from Marilao Exit to Duhat, Bocaue. The N160 concurrency ends in the city boundaries of Caloocan and Malabon, near the Eternal Gardens Memorial Park and just below Skyway and its Balintawak Exit and few meters south of the former site of Balintawak toll plaza that operated until 2005. The expressway then bends westward at Harbor Link Interchange in Valenzuela and in Tambubong Interchange in Bocaue, Bulacan. The following exit, Tabang, leads passengers to the Tabang Spur Road. The Tabang Spur Road is a four-lane, 3.36-kilometer (2.09 mi) spur road in Bulacan that branches off NLEX Main at Tabang Exit in Balagtas and terminates at a partial cloverleaf interchange with MacArthur Highway and Cagayan Valley Road at Guiguinto Exit in Guiguinto.[3] The spur road carried the final leg of the expressway until the present route was extended to Pampanga.
The expressway narrows to three lanes per direction past Tabang Exit. It continues on a straight route, traversing paddy fields on the outskirts of Guiguinto, Malolos, and Pulilan. The Asian Highway 26 (AH26) concurrency leaves NLEX at Santa Rita Exit, where it follows Maharlika Highway, also known as Cagayan Valley Road, towards Baliwag and Cagayan Valley. A few meters after Pulilan Exit is the Candaba Viaduct (officially known as Pulilan-Apalit Bridge). The bridge traverses rice paddies and swampland in the municipalities of Pulilan, Calumpit, Bulacan and Apalit, Pampanga, and crosses Apalit Bypass Road and Pampanga River before the viaduct ends. The expressway continues again on a straight alignment. After San Fernando Exit, the expressway narrows into two lanes per direction. It continues a mostly straight and gently winding route through the rural areas of Mexico, crossing Abacan and Quitangil rivers, and traversing the eastern parts of Angeles and Mabalacat. NLEX connects with Subic–Clark–Tarlac Expressway via Clark Spur Road before the main line terminates at Sta. Ines Interchange, with a toll plaza serving the exit.
Collectively known as the North Luzon Expressway Harbor Link Project (NLEX Harbor Link Project),[4] these series of expressways connect the North Luzon Expressway to various points in Metro Manila. It currently runs from Mindanao Avenue in Valenzuela to Radial Road 10 in Navotas, linking the North Luzon Expressway to the Port of Manila. Once completed, it will run from Katipunan Avenue, a component of Circumferential Road 5, in Quezon City at the east.
The original stretch of the expressway, from Balintawak Interchange in Quezon City up to Guiguinto Exit in Bulacan, was completed on August 4, 1968. It is a fully fenced limited-access highway that consisted of a four-lane rural divided roadway, nine twin bridges, one railroad overpass, seven underpasses, and three interchanges.
Originally a project of the Department of Public Works and Highways, the completion of the major portion of the job fell on the Construction Development Corporation of the Philippines (CDCP, the precursor to PNCC) to pioneer the toll concept of funding infrastructure.[5] It was carried out under the private financing scheme provided by Republic Act No. 3741.
Additional work required by the government included the construction of the Balintawak – Novaliches Interchange Complex, the Tabang Interchange, and the approach road of the underpasses.
In 1976, the NLT extension, consisting of 50.9 kilometers (31.6 mi) of concrete road, was built as part of a highways program of the International Bank for Reconstruction Development (World Bank) linking major urban centers to the production centers in the north. The project features a 4-lane limited-access highway with a 5-kilometer (3.1 mi) Candaba Viaduct, a construction innovation utilizing precast beam system, 6 interchanges, 12 bridges, and overpass/underpass structures.[1]
Between 1985 and 1991, under the administrations of Ferdinand Marcos and Corazon Aquino, the expressway was extended by another 5 kilometers (3.1 mi) from its terminus at Dau Exit to Santa Ines Exit in Mabalacat, Pampanga, with a northbound lane from Dau Exit to the future connection to SCTEX had an asphalt overlay while the southbound lane was originally a concrete road before an asphalt overlay was added upon the expressway's rehabilitation.[6] In 1998, Manila North Tollways Corporation (MNTC) was granted the concession for the expressway, manifested in a Supplementary Toll Operation Agreement (STOA). Under the STOA, the government confirmed the assignment by PNCC of its usufructuary rights, interest and privileges over the existing expressway, including all extensions, linkages and diversions in favor of MNTC. These concession rights authorized MNTC to construct, finance, manage, operate and maintain all the project roads and charge tolls thereon.[7]
Expansion and rehabilitation
The San Fernando toll plaza in 2001, few years before the rehabilitation
From February 2003 to February 2005, the expressway underwent a major rehabilitation. Works included the widening of the Balintawak–Tabang segment from 6 to 8 lanes and the Tabang–Sta. Rita segment from 4 to 6 lanes, asphalt overlay, and the demolition of old tollbooths. The main contractor of the rehabilitation work was Leighton Asia with Egis Projects as the main subcontractor for the toll, telecommunication and traffic management systems. To help maintain the safety and quality of the expressway, various rules are in effect, such as restricting the left lane to passing vehicles only and banning overloaded trucks. On February 10, 2005, commercial operations began following the Toll Regulatory Board's issuance of the Toll Operation Permit. On the same day, the operation and maintenance of the expressway was transferred from the government-owned Philippine National Construction Corporation (PNCC) to the Manila North Tollways Corporation, which would later become known as NLEX Corporation.[7][8]
On February 12, 2007, the entire stretch of the expressway began another rehabilitation regarding its drainage systems. Within this period, certain lanes of the road were closed to the traffic. This in turn caused massive traffic jams along the road and the speed limit on the construction sites were reduced from 80 km/h (50 mph) and 100 km/h (62 mph), respectively, to 60 km/h (37 mph).[citation needed] The program was finished on October 7, 2007.[citation needed]
Further extensions
NLEX in San Simon, after the 2016 expansion project
On June 5, 2010, NLEX Segment 8.1 or NLEX Mindanao Avenue Link was opened. The new spur road of NLEX is a part of the C-5 Road North Extension and is built to provide another entry point to the expressway from Metro Manila and decongest Balintawak Interchange.
On February 28, 2019, the main stretch of NLEX Segment 10 or the NLEX Harbor Link, from Karuhatan to C-3 Road, was opened to traffic.[9][10][11] On February 21, 2020, its C3–R10 Section was partially opened up to its Malabon exit ramp;[12] the remaining section to Radial Road 10 was opened on June 15, 2020.[13]
NLEX Connector is a 7.7-kilometer (4.8 mi) elevated highway serving as a connector between NLEX and SLEX. Section 1 was opened to the public, while Section 2, which is 59.12% complete as of December 2023, was partially opened and is planned to be finished in the fourth quarter of 2023.[15][16]
Proposed renaming
The main expressway has been a subject of some legislative measures for its proposed renaming. These were filed to commemorate to the historical significance and contributions of its intended namesakes, respectively. However, none has taken effect to date, as these await a counterpart measure from the Senate before it can be signed into law by the President of the Philippines.
On May 10, 2015, the House Committee on Public Works and Highways approved House Bill No. 4820 that seeks to rename the expressway to President Corazon C. Aquino Expressway (CAEX), in honor of former President Corazon Aquino, who was regarded as an icon of democracy. It was authored by Magnolia Rosa Antonino-Nadres, the then-representative from Nueva Ecija's 4th district.[17]
Currently, NLEX terminates at the Sta. Ines Exit in Mabalacat, Pampanga. Plans to continue the expressway beyond have been raised over the years, with the cooperation of DPWH, to extend the Sta. Ines Interchange towards Subic–Clark–Tarlac Expressway, also in Mabalacat.[21]
Pillars have been built on NLEX between its Balintawak toll plaza and Skyway Stage 3's Balintawak/NLEX off-ramp to accommodate a future toll road to the New Manila International Airport in Bulakan, Bulacan.[26] The future project, to be built by San Miguel Corporation, will expand the capacity of NLEX by adding new 4–5 lanes up to Marilao, which was selected for another toll road to the future airport. After the completion of this elevated toll road, NLEX will have 11–13 lanes total (3–4 lanes per direction on NLEX + 5 lanes on the elevated segment) from Balintawak Cloverleaf to Marilao, ultimately bypassing the NLEX's open section.
The toll road project, later known as the Northern Access Link Expressway (NALEX), was approved by the Toll Regulatory Board in June 2022. It would be 19 kilometers (12 mi) long from Skyway Stage 3 to a roundabout in Meycauayan, near the airport. Another 117-kilometer (73 mi) stretch would be built beyond the NMIA roundabout, ending at the southern end of the Tarlac–Pangasinan–La Union Expressway in Tarlac City. When completed, NALEX would be 136 kilometers (85 mi) long. The NALEX project costs ₱148 billion and the first segment is targeted to be completed by 2026.[27]

Toll plazas of NLEX
The tollway has two sections: an open section and a closed section.[28] The open section, which is between Bocaue Exit and Balintawak Toll Barrier and the entire NLEX Harbor Link, employs the use of a barrier toll system, which charges a flat toll based on vehicle class. It is employed to reduce the number of toll barriers (and associated bottlenecks) within Metro Manila. The closed section, which is from Bocaue Exit northwards and the northbound exit to Philippine Arena (south of Bocaue), is distance-based, charging based on the class of vehicle and distance traveled.[29] The section south of Balintawak toll barrier is toll-free, especially to vehicles travelling between Quirino Highway and Balintawak Interchange.
When the expressway was modernized, an electronic toll collection system was set up for Class 1 vehicles while prepaid magnetic cards were assigned to Class 2 and 3 vehicles to speed up transactions at toll booths. These have since been replaced by a unified ETC system operated by Easytrip Services Corporation. In accordance with law, all toll rates include a 12% Value-Added Tax (VAT). With the movement of the northernmost toll gate to Sta. Ines, the NLEX and SCTEX toll systems have been merged into one combined system, with tolls for all enclosed destinations listed.
The toll rates, implemented since June 15, 2023, are as follows:[29]
Emergency telephone boxes are located throughout the whole length of the expressway.[30] Parking bays (lay-bys) are also placed on regular intervals on the expressway, for use in emergency situations.[31]
North Luzon Expressway has eleven service areas with 5 on both northbound and southbound of the main line, mostly located on the closed toll section north of Bocaue, and one on Tabang Spur Road. Each service station hosts a gas station, a convenience store, restrooms, car repair, and lubrication services. Except for Shell Tabang NLEX, these also have restaurants and ATMs, with some also providing ETC installation and reloading for Easytrip RFID users.[citation needed]
The expressway was featured in the music video to the song "Toll Gate" by the band Hale.
It was also featured in the movie Sa North Diversion Road in 2005, based on Tony Perez's stage play of the same name. It was created by Dennis Marasigan.
From June 6–17, 2007, On North Diversion Road, the play written by Tony Perez, was performed at The Arts House, Singapore, by young & W!LD, an actor training division of Singapore's W!LD RICE Theatre.[38]
Notes
^The North Luzon Expressway is also known by its former names: the Manila North Diversion Road (MNDR), North Super Highway (NSH) and the Manila North Expressway (MNEX).
^N160 is also designated to the expressway's untolled segment from Balintawak Interchange in Quezon City to beneath the Balintawak/NLEX Exit of Skyway, near the former site of the Balintawak toll plaza, in Caloocan, officially a secondary road called the Manila North Diversion Road according to the Department of Public Works and Highways. The road is maintained by the department's Quezon City 1st District Engineering Office.[2]
^These designations only apply to the main segment of the NLEX.
