Key Differences
The term "Interstate" refers to a specific network of highways that are part of the U.S. Interstate System, established by the Federal Aid Highway Act of 1956. A "Freeway," on the other hand, is a generic term that denotes a high-speed, controlled-access roadway.
The Interstate system was designed for multiple purposes including defense, commerce, and general mobility, and it was federally funded. Whereas a "Freeway" can be a part of any road system, including state, county, or local systems, not necessarily funded or governed by federal guidelines.
All Interstates are freeways, but not all freeways are Interstates. This means while every Interstate is designed as a high-speed, controlled-access roadway, there are many freeways that are not part of the U.S. Interstate System.
The word "Interstate" is often used in American English to specifically reference the numbered highways within the U.S. Interstate System (e.g., Interstate 5 or I-5). "Freeway" can be used to describe any major highway or road that is devoid of tolls and intersections.
Interstates can easily be recognized by their unique shield-shaped blue and red signs with a number. Freeways might have varied signages based on the jurisdiction or state they are in.
