Long-distance traveling across the United States‘ major cities became possible thanks to the interstate highway system. With the help of US interstate highway map, the article will explore the highway system in tailed.
Today, there are over 40,000 miles of highways spanning thousands of United States cities, from the West coast to the East coast.
In this article, we’ll go over the main geographical landmarks of the United States and explore the intricate highway system that links it all together. The following map shows all 70 US highways as well as the states, state capitals, and major cities.

History Of The Interstate Highway System-Interstate Highway Map
The Interstate Highway System was, in a large part, inspired by a US captain named Dwight D. Eisenhower. In 1919, he led the very first U.S. Army convoy across the whole country. The trip from Washington D.C. to San Francisco took 62 days.
After the Second World War, then-General Eisenhower took notice of the solid and durable structure of German highways. Soon after he became President in 1953, he started working on an interstate highway plan. In 1956, he finally signed the Federal Aid Highway Act.
These efforts soon came to fruition, and the interstate highways spread across the whole country in the coming years. You can check this interstate highway system map as follow.
Today, the Interstate Highway System counts 70 primary highways on the U.S. mainland. The network also extends to Alaska, Hawaii, and Puerto Rico. Although highways in these areas are mostly funded by the Interstate Highway program, they are not signed as such and do not necessarily adhere to the Interstate Highway standards.
Over the years, there were setbacks during the construction. Several highways were canceled, and others were protested against and left unfinished. The highway system had to be modified on numerous occasions.
With that in mind, the Interstate Highway plan was officially completed in 1992. Since then, the network has been expanded upon, and several primary highways have been constructed.
