National Route 1 (Vietnamese: Quốc lộ 1 (or abbrv. QL.1) or Đường 1), also known as National Route 1A, is the trans-Vietnam highway. The route begins at km 0 at Hữu Nghị Quan Border Gate near the China-Vietnam border,[1] runs the length of the country connecting major cities including Hanoi, Da Nang and Ho Chi Minh City, and ends at km 2301.34[citation needed] at Năm Căn township in Cà Mau Province.

Road layout[edit]

National Route 1 runs across provinces and cities of Vietnam:


  • Total length 2,300.45 km [1]
  • Road width: 10–12 m
  • Road surface: paved with asphalt
  • Total bridges: 874 bridges, bridge load varies from 25 to 30 metric tonnes


Highway QL-1, 1968.

The National Route 1 was constructed by the French colonists in early 20th century. It has been upgraded recently by Japanese ODA as well as loans from World Bank. During both the First Indochina War and Second Indochina War (the Vietnam War), Road 1A was the site of a number of battles between Vietnamese forces and French or American troops. One of the most notable engagements was the French Operation Camargue in 1953.

In South Vietnam, there were two divided sections of the main highway from Quang Tri to Ba Xuyen (Ca Mau): QL-1 (National Highway 1) and QL-4 (National Highway 4). Extensive upgrade work was done on the QL-1, and QL-19 by the U.S. Army Corps of Engineers[2] during the 2nd Indo China War. In 1966 the 19th Engineer Battalion began to "upgrade highway QL-1 from virtually a dirt trail, to a class 31 all-weather road,[3] from Qui Nhon north to Bong Son." By 1970, the QL-1 had been upgraded all the way to Mo Duc. QL-1 bypass the route around Saigon-Bien Hoa. In the Mekong Delta, NH4 (now National Highway 1A) stretches distance of Long An province to Ba Xuyen (Ca Mau) province.


The central section of the highway, from Hữu Nghị Border Gate to Cà Mau, is planned to be duplicated by the North-South Expressway.
