Finding the quietest and least trafficked freeways in the United States varies by region, but generally, low-traffic freeways are located in areas outside major cities or in regions with low population density.

Excluding special roads in sparsely populated mountainous terrains or military areas, let's explore some of the famous freeways in the U.S. that have low traffic and are quiet.

Interstate 80 (I-80) - Nevada

Particularly, the section connecting Utah and California has relatively low vehicle traffic. As it passes through deserts and vast areas, there are fewer vehicles, and many single lanes.

Interstate 70 (I-70) - Colorado

In the outskirts or mountainous areas of Colorado, this freeway is relatively quiet. Especially as it passes through national parks and mountainous regions, the number of vehicles is low.

Interstate 95 (I-95) - Maine

Maine has a lower population density than other northeastern regions, and I-95 has very low traffic in areas outside major cities.

Interstate 25 (I-25) - New Mexico

I-25, which runs through New Mexico, has low traffic, especially as it passes through mountainous areas and deserts. It is a quiet road in sections away from major cities.

Low-Traffic and Quiet Freeways in Texas

Interstate 10 (I-10) - West Texas

I-10 runs through western Texas, and particularly the section connecting El Paso and San Antonio has low traffic. Excluding large trucks moving logistics, there are few vehicles traveling between the small towns that appear along the way, making it a region where the 80 mph speed limit freeway is nicely connected. This area crosses desert terrain and vast plains, and I think it offers a fun road trip experience on U.S. freeways.

Interstate 20 (I-20) - North Texas

I-20 is a highway that crosses eastern and western Texas, and particularly the areas outside Dallas and Fort Worth have relatively low vehicle traffic. Especially in sections with many small to medium-sized cities, the roads are less crowded and quiet.

U.S. Route 287 - North Texas

U.S. Route 287 is a major highway that runs through northern Texas, starting from Fort Worth and continuing north, and this section is known for being a quiet road outside of major cities. It connects less congested areas within Texas.

Additionally, Texas has many wide rural areas and deserts, so roads connecting the outskirts of the state or small towns generally have low traffic.
