Thought the Interstate was federally controlled ....
The last 3 federal transportation acts make this perfectly legal. It’s the wave of the future.
No, the Interstate system is owned by the states, DC, and Puerto Rico (There are three unsigned interstates in PR). Federal money is granted to the states to build a portion of it (Chargeable interstates), other portions are built out of state funds only (non-chargeable interstates).
The US government owns one bridge in Washington, DC only.
Aside from a few notable exceptions (Interstate 99, the Bud Shuster vanity road) the designation of roads in the system is controlled by the American Association of State Highway and Transportation Officials (AASHTO).
