# Why Was the US Interstate Highway System Linked to National Defense?

The US Interstate Highway System is often described as a major public works project, but its connection to national defense also appears in accounts of its creation. What specific security concerns shaped the system’s design or helped build political support for it?

I’m especially curious about how the defense rationale fit alongside everyday goals such as faster travel and trade.
