And at one point in the East Bay, you can drive on I-80 East and I-580 West [at the same time.](https://upload.wikimedia.org/wikipedia/en/4/41/West_580_with_East_80.jpg)

> Good point. While obviously an interstate highway can’t be expected to go all the way to the shoreline, I’d think that to qualify as a true E-W cross-country route, it should end somewhere in a city or town on the Atlantic or Pacific coast.

Given the desire for Interstates to end at other Interstates, I should think ending in a coastal state would be sufficient. Or within 100 miles of the coast.
