Route Coloniale 9 was built by the French in the early twentieth century to do something ambitious: push a road over the Annamite Range and connect the Vietnamese coast to the Mekong River towns of Laos. The geography that made this route strategically necessary also made it physically brutal — the mountains don't yield easily, and the road climbs and drops through terrain that becomes a natural chokepoint. As National Route 9, the road runs 82 kilometres across Quảng Trị Province, from Đông Hà near the coast to Lao Bảo on the Vietnamese-Laotian border, passing through Khe Sanh. In the 1960s and 1970s, that stretch became one of the most fought-over corridors in Southeast Asia.

The route has been progressively upgraded since, and with the comple...
