National Route 22 (Vietnam)
National Route 22 is a highway in southern Vietnam stretching from the northwestern outskirts of Ho Chi Minh City, the commercial centre of the country, towards the Cambodian border to the northwest. It is the main route for trade and traffic between Cambodia and southern Vietnam. Under French administration, this highway was designated National Road 1.
The highway starts on the northwestern outskirts of Ho Chi Minh City, near Hóc Môn. The highway passes through the town of Củ Chi before reaching Trảng Bàng and Gò Dầu near the Cambodian border. At Gò Dầu, one branch diverges into the border town of Mộc Bài before crossing the border and becoming National Highway 1 in Cambodia. The main branch of National Road 22 continues northwest into Tây Ninh Province, the heartland of the Cao Dai religion before reaching the provincial capital of Tây Ninh. The highway continues north, reaching a border crossing at the town of Trai Bi and becoming National Route 1 in Cambodia, which leads to the regional centre of Kampong Cham.
