The first roads appear to have been built in 4000 BC In Egypt, but the first paved roads were built in Babylon (bab-uh-lon) in 625 B.C.
The roads are there to reduce the congestion of cars. They are paved pathways to help cars travel easier.
Positive- helps people get to where they need to go. Roads make traveling easier and faster, and roads connect different places. They also don't have a bunch of rocks like trails do.
Negative- You have to take down trees to put new roads in. Also to build roads you have to blast mountain sides or take down a house here and there. Roads also go through natural areas and animals are in danger. Roads also increase pollution by allowing more cars in more areas.
How it works.
They make traveling easier by making smoother surfaces to drive on. They also keep people from getting lost with street names. They connect major locations.
Today's invention of roads have better surfaces. Thomas Telford and John Loudon McAdam invented modern tarred roads. Telford designed the idea of raising the middle of the road to help water drain off the road. Today's roads also have reflectors, many lanes, painted lines, rumble strips, barriers, and they are organized. People have also added bridges.
Roads made travel easier from north to south, and trips that took days took hours with the invention of roads. Small towns that were once isolated from what was going on in the world, and with the invention of roads, towns were able to communicate with each other.
