History of the US Road Network
The US road network has a rich and fascinating history, dating back to the early 19th century. The first roads in the US were primarily dirt paths and trails, used by Native American tribes and early settlers. As the country expanded and population grew, the need for a more developed road network became apparent. The Lincoln Highway, established in 1913, was the first transcontinental highway, spanning from New York to San Francisco. This was followed by the US Highway System, which was established in 1926 and consisted of a network of highways that connected major cities and urban areas.
The Interstate Highway System
In 1956, President Dwight D. Eisenhower signed the Federal Aid Highway Act, which established the Interstate Highway System. This network of highways was designed to connect major cities and urban areas, with a focus on safety, efficiency, and national defense. The Interstate Highway System has since become a vital part of the US road network, with over 47,000 miles of highways that crisscross the country.
| Highway Type | Length (miles) |
|---|---|
| Interstate Highways | 47,000 |
| US Highways | 157,000 |
| State Routes | 190,000 |
| County Roads | 3,200,000 |
