Urban planning, motor vehicles, or even wheel, first roads that were appeared on landscape thousands of years before. First roads were impulsively formed by humans walking common paths over & over to find water & food like molecules coalesced into cells & cells into more complicated organisms. The transportation of larger, heavier loads showed many limitations of dirt paths which turned into muddy bogs on the time of raining and followed introduction of wheel 7,000 years ago. The ancient stone paved roads was found about 4,000 B.C. in Indian subcontinent & Mesopotamia. Recent road-construction techniques might be traced into a process developed by Scottish engineer John McAdam in early 19th century. McAdam excelled multi-layer roadbeds with soil & crushed stone that was then settled down with heavy rollers. Modern day asphalt roads are able to support vehicles that emerged in 20th century. It was built upon McAdams' methods with adding tar as a binder.
