All roads, large or small, in all countries of the world have very much the same history. Most began as narrow animal paths through the forest. Later these paths were widened so they could be used to get food to the market.
The Life of a Road tells how better roads can be built over these early ones, and how the most modern high ways are built today.
Readers will learn, too, the importance of roads in today's world. Roads tie a coutry together and are the means for getting food to the maket and goods from the market to the people.
We have built an age on wheels. Now we must build the roads on which it can travel.
