Having grown up in “toll booth” states, I’m not particularly put out by the idea of Rhode Island putting up a few booths on the RI/CT line to make some money for the state (especially for infrastructure), as suggested by the ProJo editors. But two points–one a great big, red warning flag–they make are worth highlighting:

…care must be taken lest the toll system, presumably to be run by the Rhode Island Bridge and Turnpike Authority, become a patronage nest to rival the Massachusetts Turnpike Authority.
More generally, we should remember that high costs from unfairly sky-high public-employee benefits (wages themselves are not the problem; they are fair); poorly managed social-service programs; and other administrative woes are the biggest state government fiscal problems, not too little revenue.
