National Route 1 (N1) is a primary national route that forms part of the Philippine highway network, running from Luzon to Mindanao. Except for a 19-kilometer (12 mi) gap in Metro Manila and ferry connections, the highway is generally continuous. Most sections of N1 forms the Pan-Philippine Highway except for sections bypassed by expressways.

Route description

N1 follows a route that runs from Laoag in Ilocos Norte to Zamboanga City via Bicol Region, Eastern Visayas and eastern parts of Mindanao. The highway connects most major regional centers on its route and runs through different landscapes. The highway is mostly named Maharlika Highway, but other sections use different names.

Ilocos Region

Main articles: Pan-Philippine Highway and MacArthur Highway

Patapat Viaduct

N1 begins at the intersection with N2 (Manila North Road) and N100 (Laoag Airport Road) in Laoag as Manila North Road or MaNor. It then crosses Padsan River via Gilbert Bridge and enters the city proper of Laoag, where it splits before turning to the east in front of Ilocos Norte Provincial Capitol, briefly following J.P. Rizal Avenue before turning to General Segundo Avenue; both are principal city streets passing through the city proper and through its outskirts. Approaching Bacarra, it becomes a rural highway. At Bacarra, it bypasses the town center to the north and runs through a rural area, and then enters Pasuquin, where it serves as a major municipal street. Between Bacarra and Burgos, it becomes a rural two-lane highway and passes through interspersed barangays along the South China Sea (West Philippine Sea) coastline. It soon climbs the mountains upon approach to Burgos, where the highway directly serves the town. The highway zigzags through the rough terrain, and overlooks the beach where Bangui Wind Farm lies. It then passes through Bangui, where it runs as a major street on the town center, crosses Bulu River, and enters Pagudpud, which bypasses the town proper. N1 runs through the foothills that mark the edge of the Northern Luzon Cordillera and runs close to the coastline of Bashi Channel, where the highway zigzags through the cliffs through the Patapat Viaduct, a 630-meter (0.39 mi) viaduct that is required for the highway to pass the steep cliffs marking the northern edge of the Cordillera Range.

Cagayan Valley

Main articles: MacArthur Highway, Cagayan Valley Road, and Pan-Philippine Highway

Bangag-Magapit Road
Location	Aparri – Lal-lo, Cagayan
Length	28.84 km (17.92 mi)

Entering the Cagayan Valley region, N1 follows Manila North Road up to barangay Bangag, Aparri, where it turns south and becomes Bangag-Magapit Road up to the Magapit Interchange in Lal-lo. In Lal-lo, N1 is carried by the Magapit Suspension Bridge over the Cagayan River before meeting the Magapit Interchange. At the interchange, it turns southeast and becomes Cagayan Valley Road from Magapit, Lal-lo to Tuguegarao, running parallel to the Cagayan River. In Tuguegarao, N1 turns east at its intersection with N106 (Tuguegarao Diversion Road) and N51 (Santiago–Tuguegarao Road) to bypass the city proper and run parallel to the Cagayan River up to Reina Mercedes, Isabela. It then enters the province of Isabela and Nueva Vizcaya as Maharlika Highway, although it is alternatively called Cagayan Valley Road up to Guiguinto, Bulacan. It serves as the main artery of Isabela alongside N51. At Nueva Vizcaya, N1 traverses the mountainous terrain between the Cordillera and Sierra Madre Mountain Ranges.

Central Luzon

Nueva Ecija

Main article: Pan-Philippine Highway

The highway soon enters Nueva Ecija at Carranglan. It then enters the poblacion of San Jose and Muñoz before turning east by its junction with N114 (Nueva Ecija–Pangasinan Road) in Santo Domingo. It then cuts through Talavera, Cabanatuan, Santa Rosa, San Leonardo and Gapan.

San Rafael to Guiguinto

Main article: Pan-Philippine Highway

Doña Remedios Trinidad Highway
Location	San Rafael – Pulilan, Bulacan

N1 as Doña Remedios Trinidad Highway in San Rafael, Bulacan

The highway soon enters Bulacan at San Miguel, where it begins on a straight route. It then enters the poblacion of San Miguel, which it bypasses, and the highway begins to curve through most of its length between San Ildefonso and San Rafael, where the route runs through rice paddies. It closely follows a transmission corridor between the San Miguel-San Ildefonso boundary and San Rafael, and a Meralco subtransmission line uses the highway on that portion. Plaridel Bypass Road intersects with Doña Remedios Trinidad Highway just before approaching the poblacion of San Rafael. The highway curves to the southwest near Baliuag, where the highway is known as Doña Remedios Trinidad Highway, while the old Cagayan Valley Road enters Baliuag. It serves as a bypass of Baliuag, with a flyover built on the intersection with another national road leading to Candaba. At Pulilan, it serves as a principal route through the town center. At Guiguinto, it crosses the North Luzon Expressway (NLEX) along with the Santa Rita Interchange, where Asian Highway 26 leaves for the expressway. It soon crosses the original route of NLEX at Tabang Interchange, where it also crosses the Philippine National Railways right of way.

Guiguinto to Meycauayan

Main article: MacArthur Highway

N1 begins to follow MacArthur Highway, which serves as a major toll-free highway over southern Bulacan. It soon enters Balagtas, where it directly passes through its poblacion. It soon crosses the Bigaa River, where it passes through residential and industrial areas, and curves upon entering Bocaue, where it bypasses the town center. A flyover restricted for use by light vehicles crosses Fortunato Halili Avenue to Santa Maria with service roads serving as frontage and heavy vehicle routes.

Entering Metro Manila, the highway follows MacArthur Highway over Valenzuela, which runs on a four to six-lane highway up to the Bonifacio Monument (Monumento) in Caloocan. N1 then turns east to follow Epifanio de los Santos Avenue (EDSA) up to Pasay. The whole road, bypassing the capital city of Manila, is notorious for congestion which causes delays as well as economic losses in the metropolis. EDSA runs through the central business districts of Metro Manila, most notably Araneta Center, Ortigas Center, and Makati Central Business District. The LRT Line 1 and MRT Line 3 utilizes the center island of EDSA on most segments between Caloocan and Pasay. N1 ends below the EDSA Flyover at N120/AH26/N61 (Roxas Boulevard) in Pasay.

A 19-kilometer (12 mi) gap in the highway is filled by the South Luzon Expressway and Skyway between Makati and Muntinlupa. It would have been filled by Taft Avenue Extension, starting from EDSA, going southwards via Quirino and Diego Cera Avenues and ends at Manila South Road below Alabang Viaduct through Alabang-Zapote Road.

N1 generally serves as a four-lane toll-free highway serving the suburban cities of northwestern Laguna alongside the tolled South Luzon Expressway. Most sections of N1 between San Pedro and Calamba serve as commercial streets bypassing the old poblacions. Most of N1 is four-lane with a painted median divider.

It enters Laguna in San Pedro, where it serves as a major commercial street, with a maximum of four lanes.

In barangay Real, the highway is alternatively known as Real Road.

Rizal Street for eastbound at its poblacion and becomes the longer zigzag road through the protected Quezon National Forest Park in the Sierra Madre mountain range. It then reaches the eastern coast of Quezon at Atimonan and traverses the municipalities of Plaridel, Gumaca, Lopez, and Calauag.

History

The direct predecessors of N1 were Manila North Road (Highway 3) from Laoag to Aparri and from Guiguinto to Caloocan, Cagayan Valley Road (Highway 5) from Lal-lo to Guiguinto, Highway 54 then in the province of Rizal, majority of Manila South Road (Highway 1) from Muntinlupa to Matnog, Samar-Leyte Road (Highway 1) from Calbayog to Santa Rita, Leyte-Samar Road (Highway 1) from Tacloban to Mahaplag and from Sogod, Southern Leyte to Liloan, Agusan-Davao Road, Davao-Cotabato Road (Highway 1) from Davao to Digos, Lanao-Cotabato Road (Highway 5) from Dadiangas to Mamasapano, Cotabato-Lanao Road (Highway 1) from Sultan Kudarat to Malabang, and Lanao-Zamboanga Road. With the conception of Pan-Philippine Highway (Maharlika) in 1965, more roads were constructed and added through the support of loans and grants from foreign aid institutions, including the World Bank. These roads altogether form the present alignment of N1 and Maharlika Highway, which was later designated as Asian Highway 26.

When the routes were assigned by the Department of Public Works and Highways, MacArthur Highway from Guiguinto to Caloocan, EDSA, Manila South Road from Muntinlupa to Calamba, and the segment of Pan-Philippine Highway from Laoag to Guiguinto and from Calamba to Zamboanga City were assigned as N1.
