AH 26 (26)N2

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

Route description

[edit]

N1 follows a route that runs fromLaoag inIlocos Norte toZamboanga City viaBicol Region,Eastern Visayas and eastern and southern parts ofMindanao. The highway connects most major regional centers on its route and runs through different landscapes. The highway is mostly namedMaharlika Highway orNational Highway, but other sections use different names, including alternative names assumed within somepoblacions (city or town proper).[1]

Ilocos Region

[edit]
Main articles:Pan-Philippine Highway andMacArthur Highway

N1 begins at the intersection with N2 (Manila North Road) and N100 (Laoag Airport Road) inLaoag asManila North Road (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, where thePan-Philippine Highway commences. It then briefly followsJ.P. Rizal Avenue before turning toGeneral Segundo Avenue; both are principal city streets passing through the city proper and through its outskirts. ApproachingBacarra, it becomes a rural highway. At Bacarra, it bypasses the town center to the north and runs through a rural area, and then entersPasuquin, where it serves as a major municipal street. Between Bacarra andBurgos, it becomes a rural two-lane highway and passes through interspersed barangays along theSouth China 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 whereBangui Wind Farm lies. It then passes throughBangui, where it runs as a major street on the town center, crosses Bulu River, and entersPagudpud, where it bypasses the town proper. N1 runs through the foothills that mark the edge of theCordillera Central mountain range and runs close to the coastline ofBashi Channel, where the highway zigzags through the cliffs through thePatapat Viaduct, a 630-meter (0.39 mi) viaduct that is required for the highway to pass the steep cliffs marking the northern edge of theCordillera Range.

Cagayan Valley

Bangag-Magapit Road
LocationAparriLal-lo,Cagayan
Length28.84 km[2][3] (17.92 mi)

Entering theCagayan Valley region, N1 follows Manila North Road up to barangay Bangag,Aparri. From there, it turns south and becomesBangag-Magapit Road up to the Magapit Interchange inLal-lo. Within Lal-lo, N1 is also known asLogac–Magapit Road between namesake barangays Logac and Magpit. The segment includes theMagapit Suspension Bridge, which spans over theCagayan River before meeting the Magapit Interchange.

At the interchange, it turns southeast and becomesCagayan Valley Road from Magapit, Lal-lo toTuguegarao, running parallel to the Cagayan River. In Tuguegarao, N1 turns east at the roundabout intersection with N106 (Tuguegarao Diversion Road) and N51 (Santiago–Tuguegarao Road) to bypass the city proper towardsPeñablanca and run parallel to theCagayan River up toReina Mercedes, Isabela. It then enters the province ofIsabela andNueva Vizcaya asMaharlika Highway, although it is alternatively called Cagayan Valley Road up toGuiguinto,Bulacan. It serves as the main artery of Isabela alongside N51. InSantiago, Isabela, it turns southwest at the Mabini Rotonda, its intersection with N51, and becomes a one-way northbound route. Southbound traffic is redirected via R.C. Miranda Road and Boulevard to bypass this one-way section.

At Nueva Vizcaya, N1 runs parallel to and crosses the Magat River. InSolano, it navigates through thepoblacion locally asJ. Manzano Street, cutting through asJ.P. Rizal Avenue, and finally exiting asAquino Avenue towards its segment bypassingBayombongpoblacion. Further inSanta Fe, it then reaches theDalton Pass, whereSierra Madre andCaraballo Sur meet.

Although Cagayan Valley Road is limited to Cagayan, its name also alternatively extends up to N1's section inBulacan.

Central Luzon

[edit]

Nueva Ecija

[edit]
Main article:Pan-Philippine Highway

The highway soon entersNueva Ecija atCarranglan. It then descends to theplain terrain inSan Jose as it approaches thepoblacion. It then cuts throughMuñoz andTalavera before turning east by its junction with N114 (Nueva Ecija–Pangasinan Road) inSanto Domingo. It then cuts through Talavera (once again, this time with thepoblacion),Cabanatuan,Santa Rosa,San Leonardo andGapan.

Bulacan

Doña Remedios Trinidad Highway
DRT Highway
LocationSan RafaelPulilan,Bulacan

N1 soon entersBulacan atSan Miguel, where it begins on a straight route. It then enters thepoblacion of San Miguel, which it bypasses, and the highway begins to curve through most of its length betweenSan Ildefonso andSan Rafael, where the route runs through rice paddies. At its intersection with San Rafael Municipal Road, the highway curves to the southwest to followDoña Remedios Trinidad Highway (DRT Highway) until the intersection of the old Cagayan Valley Road and Esguerra Street inPulilan. DRT Highway serves as a bypass of the old Cagayan Valley Road throughBaliwagpoblacion. At Guiguinto, it crosses theNorth Luzon Expressway (NLEX) along with the Santa Rita Interchange, whereAsian Highway 26 leaves for the expressway. It soon crosses the original route of NLEX at Tabang Interchange.

Guiguinto to Meycauayan
[edit]
Main article:MacArthur Highway
N1 asMacArthur Highway with the Bocaue Flyover inBocaue. This segment, however, is not part of the AH26 concurrency.

Past Tabang Interchange, N1 begins to follow Manila North Road once again, this time asMacArthur Highway, which serves as a major toll-free highway over southern Bulacan. It soon crosses thePhilippine National Railways right of way and entersBalagtas, where it directly passes through itspoblacion. It soon crosses the Bigaa River, where it passes through residential and industrial areas, and curves upon enteringBocaue, where it bypasses the town center. A flyover restricted for use by light vehicles crossesFortunato Halili Avenue toSanta Maria with service roads serving as frontage and heavy vehicle routes. The highway then curves and traverses through the residential barangays of Bocaue and soon entersMarilao andMeycauayan.

Metro Manila

[edit]

Valenzuela to Pasay

[edit]
Main articles:MacArthur Highway andEDSA
A reassurance marker for N1/AH26 atEDSA northbound inQuezon City

Entering Metro Manila, the highway follows MacArthur Highway overValenzuela, which runs on a four to six-lane highway up to theBonifacio Monument (Monumento) Circle inCaloocan. There, the Asian Highway 26 concurrency returns on N1 as it turns east to followEpifanio de los Santos Avenue (EDSA) up toPasay. The whole road, bypassing the capital city ofManila, 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 notablyAraneta Center,Ortigas Center, andMakati Central Business District. TheLRT Line 1 andMRT 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 theSouth Luzon Expressway (SLEX) andSkyway betweenMakati andMuntinlupa. It would have been filled byTaft Avenue Extension, starting from EDSA, going southwards viaQuirino andDiego Cera Avenues and ends at Manila South Road below Alabang Viaduct through Alabang–Zapote Road.

N1 resumes below the Alabang Viaduct ofSouth Luzon Expressway (SLEX/E2/AH26) inAlabang,Muntinlupa, where it intersects with SLEX's Alabang Exit, East Service Road, N411 (Alabang–Zapote Road), and N142 (Montillano Street). The highway assumes the nameMaharlika Highway,Manila South Road, or locally,National Road orOld National Road. It runs as a commercial artery through the city up to the boundary withLaguna inSan Pedro over theTunasan River. However, this section does not assume the Asian Highway 26 concurrency, which is designated instead to SLEX.

Calabarzon

[edit]

San Pedro to Calamba

[edit]
N1 asManila South Road inBiñan. This segment, however, is not part of the AH26 concurrency.

N1 generally serves as a four-lane toll-free highway serving the suburban cities of northwestern Laguna alongside the tolledSouth Luzon Expressway. Most sections of N1 betweenSan Pedro andCalamba serve as commercial streets bypassing the oldpoblacions. 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. It then enters the cities ofBiñan,Santa Rosa,Cabuyao, and Calamba, where it turns southwest past its intersection with N66 (Calamba–Pagsanjan Road) at the Calamba Crossing. In barangayReal, the highway is alternatively known asReal Road.

Calamba to Tayabas

[edit]
Main article:Pan-Philippine Highway
N1 inTurbina,Calamba

N1 soon crosses the South Luzon Expressway at the Calamba Exit, where the concurrency with theAsian Highway 26 returns on the highway, and passes through several western barangays in Calamba. It then enters the province ofBatangas inSanto Tomas, where it intersects withSTAR Tollway and bypasses thepoblacion. At the Santo Tomas Roundabout, where it meets N4 (Jose P. Laurel Highway) and Governor Carpio Avenue, it turns southeast as it leaves the province. It then re-enters the province of Laguna throughAlaminos and thenSan Pablo, bypassing itspoblacion.

N1 then enters the province ofQuezon atTiaong. There, it passes theVilla Escudero plantations and the site of the future Tiaong Interchange of SLEX Toll Road 4, then cuts through thepoblacion asDoña Tating Street and then veers east asDon V. Robles Street. It then traverses the municipalities ofCandelaria (asRizal Avenue through thepoblacion) andSariaya (asGeneral Luna Street through thepoblacion) and the city ofTayabas, where it turns southeast towardsLucena at the Calumpang Junction.

InPagbilaopoblacion, N1 briefly splits intoMSR Diversion Road (collective name for the segment locally known asC.M. Recto Street andPornobi Street, respectively) for westbound traffic andJ.P. Rizal Street for eastbound traffic. Onto the area of the protectedQuezon National Forest Park in theSierra Madre, it then becomes alternatively known asNew Diversion Road, the longer road bypassing the Old Zigzag Road alignment cutting through the park.

The route entersAtimonan, bypassing thepoblacion before reaching Quezon’s eastern coastline. It then continues throughPlaridel and thenGumaca, where it becomesJ.P. Rizal Street in thepoblacion south of the Gumaca River, then shifts eastward asA. Bonifacio Street toward Lopez. WithinLopezpoblacion, it is known asGeneral Vera Avenue before traversingCalauag.

The Visayas section of N1 begins at the intersection with N670 (Allen–Catarman Road / Allen Diversion Road) and Allen Old Road inAllen,Northern Samar, just south of the Port of Allen. It runs mostly along the western coast ofSamar Island, particularly the provinces of Northern Samar andSamar and notably through the cities ofCalbayog andCatbalogan. Through the Calbayogpoblacion west of the Calbayog River, it is also known asJose D. Avelino Street orSenate President Jose Avelino Avenue. In thepoblacion ofSanta Margarita, Samar, it briefly becomes a one-way southbound road as northbound traffic is diverted to the Santa Margarita Old Route, which covers short segments of Ramon Calagos and Barrantes Streets. It then climbs a mountainous terrain as it approachesGandara, where it straddles along the Gandara River and Tan-Correche Creek. It then enters the landlocked town ofSan Jorge and returns to the western coast of Samar atTarangnan. Further south in Catbalogan, it traverses through thepoblacion along local streets such asDel Rosario Street (where it briefly splits at the junction with Mabini Avenue, in front ofSaint Mary's College of Catbalogan),Curry Avenue,San Roque Street, andRizal Avenue Extension.

History

[edit]

The current alignment of N1 was formed by the integration and expansion of several colonial-era and post-war highway systems. Its direct predecessors included:[13][14][15][16][17][18][19]

More roads were later constructed and added to integrate with the present alignment of N1 andPan-Philippine Highway (also known as Maharlika Highway since 1979),[21] which was conceived in 1965 as the country's principal transport backbone and later designated as Asian Highway 26 (AH26).[22]

In 2014,Department of Public Works and Highways assigned the segment ofPan-Philippine Highway from Laoag to Guiguinto and from Calamba toZamboanga City,MacArthur Highway from Guiguinto to Caloocan,EDSA, and Manila South Road from Muntinlupa toCalamba as N1.
