Impasse

Yesterday, the Big Dig claimed another victim, a 64-year-old man suffering from a heart attack who died inside an ambulance that couldn't navigate through traffic. The trip from Logan to Boston Medical Center should have taken 4 minutes. Instead, it took 25. They had to call a state police cruiser to escort the ambulance the wrong way through the eastbound tunnel — through the same section that has been closed since 12 tons of concrete killed Milena Del Valle two weeks ago.

Things are going to get worse before they get better.
