National Route 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, runs the length of the country connecting major cities including Hanoi, Đà Nẵng, Hồ Chí Minh City, Cần Thơ, and ends at km 2482 at Năm Căn commune in Cà Mau province.

History

The National Route 1 was constructed by the French colonists in early 20th century. 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 Quảng Trị to Ba Xuyên (Cà Mau): QL-1 (National Highway 1) and QL-4 (National Highway 4). It bypassed Saigon-Biên Hòa. Extensive upgrade work was done by the U.S. Army Corps of Engineers 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, from Qui Nhơn north to Bong Son." By 1970, the QL-1 had been upgraded all the way to Mo Duc.

The road was upgraded using official development assistance from Japan, and loans from the World Bank.
