King’s Highway (built 1650 to 1735) decades before the United States became a country, which makes the King’s Highway the oldest road in America. In 1735, it was basically a trail. By 1750 the entire road was in place. The road is 1,300 miles (2,100 km) long and connected Charleston, South Carolina to Boston, Massachusetts. The King’s Highway was the most important road in colonial America and served as the major transportation route for the colonies. A documentary film was created about the King’s Highway and many of the landmarks along the road. It played a critical role in the ultimate independence of the United States from England even though it was ordered to be built by Charles II of England. Today, highways and modern roads cover most of the original route. There are hundreds of historic places along the 1,300 mile highway.
