The Big Dig, that is:

When the [high occupancy vehicle lanes] were opened two years ago, with their very own tunnel under the Fort Point Channel, state officials predicted they would change the way Boston area drivers commute to work.

The roads sit largely unheralded and unused, given that the adjacent Interstate 93, the highway they are supposed to relieve, is rarely clogged by traffic in that area. The cost for these three miles of open pavement: an estimated $250 million.

And as if that wasn’t good enough:

The high-occupancy vehicle lanes were conceived nearly two decades ago to allow the Big Dig to meet state and federal clean-air rules by encouraging shared commutes.

I guess we need to go over this again:

High Minded Politicians + Government Regulations + Government Pork = Yet another empty, expensive, useless government project. Ah, America.
