What Are the Different Parts of the Highway Transportation System?
The highway transportation system in the United States can be divided into several different parts: the interstate highway system, the national highway system, state and local highways, and private roads.
Interstate highways are the main arteries of the highway transportation system, connecting different parts of the country.
The interstate highway system was created by the Federal-Aid Highway Act of 1956. It is a network of freeways that crisscrosses the country, linking major cities and metropolitan areas.
The interstate highway system comprises over 47,000 miles (75,000 km) of roadways.

The parts of the interstate highway system
The interstate highway system can be further divided into three parts: the primary interstate system, the auxiliary interstate system, and the urban interstate system.
Urban Interstate System
The primary (urban) interstate system is the core of the network, connecting large cities and metropolitan areas. It consists of over 25,000 miles (40,000 km) of roadways.
Examples of the primary interstate system include:
Interstate 90 (I-90), which runs from Seattle, Washington to Boston, Massachusetts
Interstate 80 (I-80), which runs from San Francisco, California to Teaneck, New Jersey
Interstate 70 (I-70), which runs from Baltimore, Maryland to Cove Fort, Utah
Auxiliary Interstate System
The auxiliary interstate system consists of over 22,000 miles (35,000 km) of roadways. It connects smaller cities and rural areas to the primary interstate system.
Examples of the auxiliary interstate system include:
Interstate 5 (I-5), which runs from Mexico to Canada along the West Coast of the United States
Interstate 35 (I-35), which runs from Duluth, Minnesota to Laredo, Texas
Interstate 95 (I-95), which runs from Maine to Florida along the East Coast of the United States
National Highway System
The National Highway System (NHS) is a network of over 160,000 miles (260,000 km) of roadways that are essential to the economic and defense infrastructure of the United States.

The parts of the national highway system
The national highway system can be further divided into three parts: the interstate system, the national freeway system, and the national scenic byways system.
More about the national highways

It is a network of highways that connects different parts of the country, including rural and urban areas.
The national highway system comprises over 160,000 miles (257,000 km) of roadway.
How many national highways are there?
There are currently 1,021 national highways in the United States.

The national highways go to all 50 states and the District of Columbia.
National highways are secondary roads that are also part of the national highway system.
They connect smaller towns and rural areas to the interstate highway system. National highways make up over 12,000 miles (19,000 km) of the highway transportation system.
Which states have the most national highways?
Texas has the most national highways with 1,163, followed by California with 1,085 and Florida with 932.

All-American Roads
These are the most scenic roads in the country and must meet certain criteria, such as having unique features that cannot be found anywhere else in the United States.
National Scenic Byways
These roads provide a unique and enjoyable experience for travelers. They must meet certain criteria, such as having outstanding scenery or historical significance.
