https://thehill.com/policy/transportation/335318-trump-congress-head-for-fight-over-tolls “Tolling is generally restricted on interstate highways. This restriction prevents public and private investment in such facilities,” the White House fact sheet says. “We should reduce this restriction and allow the states to assess their transportation needs and weigh the relative merits of tolling assets.”

When Congress created the Interstate Highway System in 1956, states were prohibited from tolling the interstates, with the exception of states that already had tolls in place.

But lawmakers have slowly chipped away at the ban. Tolling is now allowed to add new capacity to an interstate highway or to reconstruct a bridge.

Congress also created a pilot program in a 1998 highway bill that allows three states to explore tolling on their interstates, though none of them have yet utilized the program.

If tolls are illegally added to any such road, the federal highway money is GONE and needs to be factored in to the CT revenue projections.

“..When Congress created the Interstate Highway System in 1956, states were prohibited from tolling the interstates..”

As I recall illannoy had tolls from the get go. Supposed to pay off the bond matching funds by early 80’s. However, they were such a rich source of revenues, patronage jobs, clouted Chicago contractors, etc that they have been perpetuated.
