There are what are called "Federal Aid Roads" but these include any road that a state or local government receives money for to build or maintain. Just because a road is an interstate or US highway does not make it a "federal" highway. All interstate numbered, US numbered and state numbered highways are state highways.
So the answer to your question is: no, there is no "federal highway." Now, to confuse you a little more, US 1 in Broward County, FL is named "Federal Highway" but it is a state road. All I was trying to point out is that there cannot be competing sets of standards for building and signing roads within a state. It would not happen. If a state uses metric for road construction, it is for all the roads in its jurisdiction rather than just federal aid highways. Of course, local governments (county and municipal) may have different ideas.
