Highways are paths or ways connecting major towns or cities, or states. It is a busy road with different lanes. It is usually the quickest route for driving from one place to another.
The word "HIGHWAY" goes back to the elevated Roman roads with a mound or hill formed by the earth from the side ditches thrown towards the center, thus highway.

WHY DO WE NEED HIGHWAYS? : Highways play an important role in making travel easier and more expedient. A well-functioning highway system allows businesses to hold less inventory, use just-in-time inventory procedures, enjoy greater locational choice, and change distribution or production patterns in other ways. These provide human access to different places.
However, there are some disadvantages of Highways construction. Highways are vulnerable to season and weather impacts. Accidents and Breakdowns can take place if not constructed properly. But despite disadvantages, highways contribute to the economy. The interstate highway system reduces manufacturing and distribution costs in the domestic market. Highways also bring important social benefits.
