The Most Populous City in the Lower 48 States Without an Interstate Highway

When discussing the most populous city in the contiguous 48 states of the United States that does not have an interstate highway within its metropolitan area, several intriguing facts come to light. Understanding the geography and infrastructure of these cities can provide a clearer picture of the peculiarities of the US transportation network.

Geographical Insights into the United States

To answer this question effectively, one might begin with a thorough examination of the geography of the contiguous 48 states. A USA map can be an invaluable tool for understanding the distribution of major cities, highways, and natural features. This map serves as a crucial reference, revealing the cities that stand out due to their unique conditions.

Among the larger cities in the region are such places as Fresno, California, with an approximate population of 500,000, and Bakersfield, California, which has around 400,000 residents.

Both cities lie along what used to be US Route 99, which has since been elevated to an Interstate-grade freeway, CA 99. These roads run parallel to the I-5 interstate highway, which is located about 40 miles to the east. This configuration means that while major roadways serve these cities efficiently, they do not have direct access to an Interstate highway within their metropolitan areas.

Population and Interstate Trends

Examining the population data for these cities, we find that Fresno and Bakersfield surpass others in their region with significant populations. However, other cities such as Fresno, California, and Mesa, Arizona, both over 500,000 in population, currently lack an interstate highway. All other cities mentioned in the lists have a population of less than 300,000.

Further Explorations

Taking a closer look at the larger metropolitan areas, we find that some cities stand out for reasons other than population size. For instance, Jacksonville in northeast Florida is the largest city by area in the contiguous 48 states, spanning an impressive 840 square miles (2,175.6 sq km). While Jacksonville has its accolades in area, it lacks an Interstate highway within its metropolitan boundaries.

Dispelling Misconceptions

The misconception that America is the United States can lead to confusion. It’s important to clarify that while the term "America" is commonly used to refer to the United States, there are other Americas, such as Brazil, which has Sao Paulo as its largest city. This can sometimes cause confusion, but for the context of this question, we are focusing specifically on the US.

Final Analysis and Alternative Examples

In the broader US context, when considering the largest city by population without an interstate highway, Honolulu, Hawaii emerges as a prime candidate. Anchorage, Alaska, is another potential city to consider, though it is less populated than Honolulu. However, Sitka, Alaska, stands out as the largest city by area in the United States, a distinction it achieves without an interstate highway.

Therefore, as the Interstate/Intrastate highway system is widely distributed in the USA, the literal answer to the question is Tokyo, Japan, the largest city by population on the planet, which is indeed not part of the Interstate Highway System in the US, highlighting the unique geography of the lower 48 states compared to international counterparts.
