US Numbered Highways: A Network of Roads and Highways Connecting the Contiguous United States

The United States Numbered Highway System (also called US Highways) is a network of roads and highways connecting the contiguous United States. The system was created in 1926 by the American Association of State Highway and Transportation Officials (AASHTO) and is maintained by state and local governments.

US Highways are numbered according to a grid system. Odd-numbered highways travel north-south, with lower numbers in the east and higher numbers in the west. Even-numbered highways travel east-west, with lower numbers in the north and higher numbers in the south. Three-digit numbered highways are spur routes of parent highways.

​US Highways are not required to be signed with mileage markers. However, our videos are labeled with the route number, origin, and destination, as well as the state in which the video is located. In some cases, a video crosses state lines. We note this in the title of the video as well as the description. Directional information is also included in the video description.

Not all of the routes we travel are included in a playlist. If you are looking for a particular route that is not in a playlist, you can try searching for it above or browsing the route listings on the page.

Some of the most popular US Highways:

US Route 1: The longest US Highway, US Route 1 runs from Maine to Florida.
US Route 66: A historic US Highway, US Route 66 is known as the Mother Road.
US Route 20: The longest east-west US Highway, US Route 20 runs from Boston to Newport, Oregon.
US Route 50: The longest north-south US Highway, US Route 50 runs from Ocean City, Maryland to Sacramento, California.
US Route 101: A scenic US Highway, US Route 101 runs along the California coast.

US Highways are a great way to explore the United States. They offer a variety of scenery, from urban landscapes to rural farmlands. US Highways are also a great way to experience American history. Many US Highways were built in the early 20th century and have played a role in shaping the country.

If you are planning a road trip, be sure to consider US Highways. They offer a unique and memorable way to see the United States.
