America's most notorious union-only project labor agreement (PLA), Boston's "Big Dig," will come to completion with the end of 2007. What a bittersweet day for citizens of Boston. The Associated Press puts it this way:

"Don't expect any champagne toasts."

As also noted by the AP, the Big Dig's history was "littered with wrong turns" such as a major tunnel leak in 2004, as well as the tragic death of a motorist in 2006.

Financially, the Big Dig sapped taxpayers for $14.8 billion, over five and a half times the original cost estimate of $2.6 billion.

This train wreck of a public construction project should serve as "exhibit A" of the gluttonous waste inherent in PLAs. Such projects are also a "lose-lose" for employees that wish to remain nonunion because they are blackballed from working, as well as for the taxpayers forced to foot the bill.
