I have paid tax - the federal gas tax.
Interstates are Federal roads, NOT state roads.
“Interstates are Federal roads, NOT state roads.”
Actually the States build the interstates highways and they are the property of the state they exist in.
“Interstate highways and their rights of way are owned by the state in which they were built. The last federally owned portion of the Interstate System was the Woodrow Wilson Bridge on the Washington DC Capital Beltway. The new bridge was completed in 2009 and is collectively owned by Virginia and Maryland[50] Maintenance is generally the responsibility of the state department of transportation. However, there are some segments of Interstate owned and maintained by local authorities.”

the gubmint and all the leftists would make every road a toll toad if they could. If The People don't push back this will become a reality.
Actually, all US Hiways and Interstate hiways are state roads. There are US Government specifications but the states own and build them
the question was decided in about 1825 when the first federal hiway was mandated from Cumberland Maryland to Vandalia Illinois.
I've never seen a federal snowplow on the Interstates. The contracts I bid as an estimator for the #1 highway contractor in America aren't let by the federal governemnt, but by state governments, often with a federal contribution.
