Visit our Big Dig special report page for full coverage and photos of the tunnel collapse.
The NTSB has released an extensive set of photos that graphically depict mind-boggling negligence in Boston's Big Dig. Poor engineering, incompetence and perhaps worst, an utter lack of inspection over a known problem resulted in death, injury, runaway costs and endless inconvenience for drivers. Imagine driving over a bridge with visibly dangerous cracks in the girders - and doing nothing about them. That is the story of the Big Dig ceiling.
Tell us what you think after viewing these dramatic photos. When it comes to trust in public works, they are alarming to say the least.
