Is there a highway with no speed limit in the US?

That's right, there's a 40 mile stretch of a toll road between Austin and San Antonio where you will be able to legally drive 85 miles per hour — the highest speed limit on any highway in the U.S. Since 1995, 35 states have raised speed limits to 70 MPH or higher on some portion of their highways.
