North America
The first macadam road built in the United States was constructed between Hagerstown and Boonsboro, Maryland, and was named at the time Boonsborough Turnpike Road. This was the last section of unimproved road between Baltimore on the Chesapeake Bay to Wheeling on the Ohio River. Before it was macadamized, stagecoaches travelling the Hagerstown to Boonsboro road in the winter had taken 5 to 7 hours to cover the 10-mile (16 km) stretch.
