Tarmacadam is a concrete road surfacing material made by combining tar and macadam (crushed stone and sand), patented by Welsh inventor Edgar Purnell Hooley in 1902. It is a more durable and dust-free enhancement of simple compacted stone macadam surfaces invented by Scottish engineer John Loudon McAdam in the early 19th century.
The National Road (also known as the Cumberland Road) [1] was the first major improved highway in the United States built by the federal government.Built between 1811 and 1837, the 620-mile (1,000 km) road connected the Potomac and Ohio Rivers and was a main transport path to the West for thousands of settlers.
In addition, a macadam road was constructed from Main Street in Myersville to the first crossing of Middle Creek north of the town. [6] The gap between that crossing of Middle Creek and Ellerton was filled by a concrete road in 1928. [7] Wolfsville Road from Grossnickel to Middlepoint was started in 1930. [8]

The first segment of modern MD 212 to be built as a modern road was Riggs Road from Washington to the Adelphi Mill, which was then known as the Riggs Mill. The 14-foot-wide (4.3 m) macadam road was built in two sections, the first one from Ager Road near the modern MD 410 intersection to Northwest Branch opposite the Riggs Mill by 1910.
