15. 157,724 Miles Of Highway
Even though railroads in the United States may be relics of the past, highways are still in use. The Federal Highway Administration (FHWA) is the government agency in the United States that is in charge of adding to the already huge number of miles of highways.
There are 157,724 miles of roads that go all over the continental United States of America as of today. Since these roads connect every state, town, and county, there is a lot of maintenance that needs to be done on them. Surprisingly, maintenance is not done by the federal government. Instead, it is given to the state governments. Because of this, some roads are kept in better condition than others.
16. Australia Vs The United States
Australia is in a unique place in the world because it is both an island and a continent. This island country in the Pacific Ocean is home to the largest coral reef in the world as well as some of the most poisonous plants and spiders in the world. It is about the same size as the United States, so it is on the same level as that country.
This map shows that the U.S. is about 27% bigger than Australia. This can be compared to how big Australia is. Even though the country is smaller, it has a much smaller population that needs to be taken care of. The United States needs every inch of land it can get because the number of people living there is growing quickly.
