What was a significant effect of the interstate highway system on trucking?

The development of the interstate highway system significantly transformed the logistics and transportation industry, particularly in facilitating long-distance freight transport. This nationwide network of highways allowed for faster and more efficient movement of goods across vast distances, reducing transit times. The interstate highways are designed to accommodate large vehicles and facilitate uninterrupted travel, which is essential for the trucking industry. This advancement enabled carriers to expand their routes and service areas, making it possible to transport goods more efficiently and reliably than before.

In addition, the interstate system reduced reliance on older roads that were not conducive to heavy trucking, thereby streamlining the supply chain and enhancing the overall capability of the trucking sector to meet the demands of a growing economy.
