Via Atrios, the Big Dig is just about done:

bq. When the clock runs out on 2007, Boston will quietly mark the end of one of the most tumultuous eras in the city’s history: The Big Dig, the nation’s most complex and costliest highway project, will officially come to an end. Don’t expect any champagne toasts. After a history marked by engineering triumphs, tunnels leaks, epic traffic jams, last year’s death of a motorist crushed by falling concrete panels and a price tag that soared from $2.6 billion to a staggering $14.8 billion, there’s little appetite for celebration.

$14.8bn is an awful lot of money to spend on a road project to reconfigure the infrastructure of a large city by putting a chunk of the Interstate underground. As Duncan says, it’s slightly less than two months worth of U.S. government spending in Iraq.
