There are three systems of major highways in the United States of America: The Interstate Highway System, the United States Numbered Highway System (also known as U.S Routes or Highways), and State Highways/Routes/Roads.

Interstate Highways[edit | edit source]

Interstate Highways are controlled-access highways, which mean they don't have intersections, traffic signals, or access to property. They are written in the format Interstate X (I-X).

An example of an Interstate Highway in American Truck Simulator

There is a number system for the main Interstates. Interstate freeways going west-east have even numbers and are numbered south to north (e.g. Interstate 8 is in the southern US and Interstate 90 is in the northern US). Interstate freeways going south-north have odd numbers and are numbered west to east (e.g. Interstate 5 is in the western US and Interstate 25 is east of that).

The main Interstate freeways featured in American Truck Simulator are:

There are also several auxillary Interstates featured in American Truck Simulator, which are numbered with a number in front of the originating Interstate. Odd means that its a spur and even means that it loops back:

Business Loop shield

Some Interstates also have business loops. They are short roads that connect the Interstate exits with other major highways.

US Highways[edit | edit source]

US Highway shield

US Highways are a system of highways and roads. The numbering system for US Highways is the opposite of that for the Interstates. East-west routes have even numbers and are numbered north to south. North-south routes have odd numbers and are numbered east to west. The format for US Highways is U.S. Route XX (US XX):

State Highways[edit | edit source]

States in the US also have their own highway systems:

Note[edit | edit source]

  • Because the game is set in two different scales – a 'regular' scale (1:20) and a 'city' scale (1:3) – these lengths are not to scale.
