Why are streets usually asphalt and sidewalks usually concrete?

In: 10

Answer 1

Concrete lasts a long time but when it is time to replace is very difficult and expensive to do. A concrete sidewalk will last basically forever as people don’t cause enough wear and tear to damage it. A roadway even when concrete will need to be replaced every few years. It’s better to use fast cheap asphalt every 5 years then slow expensive concrete every 10 years.
