about federal highways

Оказывается, федеральное правительство США не имеет никакого отношения к сети federal highways - их всегда строили и поддерживали штаты.

The numbers and locations are coordinated by the American Association of State Highway and Transportation Officials (AASHTO). The only federal involvement in the AASHTO is a non-voting seat for the United States Department of Transportation.
