What percentage of interstate highway miles is found in urban areas?

The correct answer indicates that approximately 35% of interstate highway miles are located in urban areas. This percentage reflects the significant role urban regions play in the overall network of interstate highways, highlighting the importance of these routes in facilitating transportation and commerce in densely populated areas. Urban interstates often serve as critical arteries for the movement of goods and services, connecting residents and businesses to broader markets.

This statistic also underscores the need for ongoing infrastructure investment and maintenance in urban settings to manage the higher traffic volumes typically found in these areas. Understanding the distribution of interstate miles is essential for effective transportation planning and resource allocation, especially given the unique challenges that urban environments present compared to rural areas, such as traffic congestion and the integration of multi-modal transportation options.

In contrast, values lower than 35% may underestimate the extent of interstate highways in urban areas, while percentages above this incorrectly imply an over-representation of urban highways in the overall interstate system. Thus, 35% accurately captures the balance between urban and rural components of the interstate network.
