A couple weeks ago we did a little bit of analysis about how long it might take to pay off the Big Dig using productivity dollars. It came on the heels of media reports on how fast a trip through Boston or to Logan had become. We are still suckers for the MBTA’s version of airport transportation – we get to avoid the tolls and don’t have to pay for parking. This video isn’t of the greatest quality but it’s really short. You’ll see how fast some folks can make their way to the airport in an automobile.
