No single interstate highway crosses the United States entirely from coast to coast. Transcontinental travel relies on a network of routes such as I-80 and I-90. These form major east-west arteries.

While no single interstate officially traverses the entire continental width, I-90 is the longest, stretching over 3,000 miles.
TL;DR
While no single interstate highway is perfectly designed to cross the entire United States from one coast to the other, routes such as I-90 and I-80 form critical east-west corridors, covering vast distances and connecting major population centers.
These interstates are part of a broader network that allows for comprehensive cross-country travel, though often requiring transitions between different numbered highways to complete the journey. The system prioritizes connectivity and efficient movement across geographical regions rather than a single, uninterrupted transcontinental path.
