The Theory of Everything: National Highways (Part-I)

By Amrit Gouda|Updated : March 10th, 2022

Thousands of years ago when there was no urban planning, no vehicles, or even the wheel the first road appeared on the landscape. Just same as the molecules unite into cells & cells into a more complex organism, similarly, the first roads were discovered. It was found by the human walking on the same path again & again in search of food & water. The small groups turn into larger ones such as the villages into towns, towns into cities same as normal walking path turn out into the formal & most suitable roads.

Street paving by stones was found during the time period around 4000 B.C. at the time of early human settlement during Indus Valley Civilisation by the people of Harappa & Mohenjo-Daro.

Roads were first created by Scottish engineer John Loudon Mcdam during the 19th Century. He built multi-layer roadbeds with soil and crushed stone together to packed down with heavy rollers to lock it all together. Over the past century, development has taken a drastic change towards new roads. After grading the surface, pavers come in and lay down fresh, continuous layers of asphalt followed directly by the rollers.

Much of the 20th century just like the Romans did lead to the development of the modern superhighway, including the German Autobahn and American interstate system.
