National Road 22 (Vietnam)

From Wikipedia, the free encyclopedia

National Road 22 (Vietnamese: Quốc lộ 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.

The highway starts on the northwestern outskirts of Ho Chi Minh City, near Hoc Mon. The highway passes through the town of Cu Chi before reaching Trang Bang and Go Dau near the Cambodian border. At Go Dau, one branch diverges into the border town of Moc Bai before crossing the border and becoming National Route 1 in Cambodia. The main branch of National Road 22 continues northwest into Tay Ninh Province, the heartland of the Cao Dai religion before reaching the provincial capital of Tay Ninh. The highway continues north, reaching a border crossing at the town of Trai Bi and becoming National Route 7 in Cambodia, which leads to the regional centre of Kampong Cham.
