Ho Chi Minh highway north to Phong Nha

This road is loosely based on the Ho Chi Minh Trail which was a road system created by the Viet Cong during the war that enabled the army to move supplies from the north to all over the country. The original road ran through Laos and Cambodia but there are still lots of pathways coming from this which would have been used back then too. This was some isolated areas with very few other vehicles coming down, the main traffic still uses the highway one which comes down the coast line.
