Is anyone watching the turnpike agency?

..... Tens of thousands of similar authorities operate around the nation, governed by appointed boards that are not beholden to legislatures. They are called "quasi-public agencies" or "public corporations" because they are financed mainly by their own collection of tolls and fees from the public, as well as by investment income and other nontax revenues. We entrust them with a long leash and light oversight.

Most of the time, these agencies remain out of the news, quietly managing public functions such as toll roads, sewer systems, school construction, and public transit. Their inner workings come to light almost exclusively amid accusations of corruption or mismanagement.
