Article I Section 9 Clause 4:
No Tax or Duty shall be laid on Articles exported from any State.
Would traveling in your car across state lines constitute an article being taxed by a toll?
Article I Section 9 Clause 5:
No Preference shall be given by any Regulation of Commerce or Revenue to the Ports of one State over those of another: nor shall Vessels bound to, or from, one State, be obliged to enter, clear, or pay Duties in another.
Same argument. Your car on an "interstate highway" is assumed to be a vessel bound from one state to another. Would paying a toll on such a road constitute paying a duty to enter another state?
I've seen tolls on state highways and turnpikes, but not on interstate highways. I know that "interstate" is a description that has likely been morphed into "federally funded," because there are many "interstate" highways that exist only within a state, such as Interstate 12 in Louisiana, or city bypasses like 680 or 595 as offshoots of I-80 in California or I-95 in Florida.
So, is putting tolls on "interstate" highways constitutional?

I-294 around Chicago is a toll road. It’s interstate AFAIK.
