The toll authority in CT made money hand over fist selling thousands of tokens that never got used, and NYC was pissed off to no end and demanded that the toll authority had to change the token. Since they had no authority to make such a demand, they had to change the subway tokens instead.
It's a bit more interesting than that.
In 1975, a Connecticut Turnpike bridge over a river collapsed, killing nearly a hundred people. In response, the Turnpike Authority had one of the big engineering consulting firms look at the Turnpike's physical plant. The conclusion was that a massive amount of money would be necessary to keep the Turnpike up to snuff.
The Connecticut Turnpike, by lucky coincidence, was also I-95 for most of its length. In those halcyon days, the federal-state split on interstates was 90-10, both for building and maintenance. By contrast, the cost of money in the Carter era was horrendous, so issuing new bonds for the Turnpike was a bad bargain. Thus, the Connecticut legislature decided to pay the Turnpike's bonds off early and free up the highway. Now that it was a garden variety interstate, the Connecticut congressional delegation went to the appropriate people with palms extended and got federal funds on a 90-10 basis to fix the highway.
Ain't this a great country or what?
