Boston's $15 Billion Danger Hole Claims Life of Woman.

BOSTON -- At least 12 tons of concrete fell from the ceiling of this city's Big Dig late Monday, crushing a woman and fueling questions about the safety of the $15 billion underground highway and tunnel system.

The ceiling collapse in a connector section of Interstate Highway 90 followed a winter in which America's most ambitious urban infrastructure project was plagued by falling debris, floods, leaking walls and concerns about construction methods in the transportation labyrinth.

Your Tax Dollars At Work.

The Danger Hole is the perfect example of a government projects.

Wikipedia's entry on the Danger Hole demonstrates this quite well:

Reports of substandard work and criminal misconduct

On August 11, 2005, it was announced that the Massachusetts State Police searched the offices of the Big Dig's largest concrete supplier in June and found evidence of faked records that hid the poor quality of concrete delivered for highway project. However, it is not believed that the low-quality concrete is connected to the hundreds of leaks discovered in the tunnels that take vehicles under Boston.

On March 19, 2006, the International Herald Tribune reported that Massachusetts "Attorney General Tom Reilly plans to sue Bechtel/Parsons Brinckerhoff and other companies if the two sides do not reach an agreement over 200 complaints of poor work in the construction of a highway system under the center of Boston, the Boston Globe reported Saturday. Reilly was said to be seeking $67 million from Bechtel and $41 million from other companies."

On May 4, 2006, six current or former employees from the concrete supplier Aggregate Industries Inc. were arrested and charged for falsifying records regarding the poor quality concrete.

On May 5, 2006, due to the controversy, Massachusetts Governor Mitt Romney announced he would return some $3,500 in political contributions from employees of Aggregate Industries.

On July 10, 2006, at approximately 11:00 p.m., a steel tieback that suspends the concrete ceiling inside the tunnel structure failed near the eastern portal of the eastbound I-90 Connector tunnel leading to the Ted Williams Tunnel in South Boston, causing four three-ton sections of ceiling to collapse. A section of ceiling fell on top of a car traveling through the tunnel, killing newlywed 38-year-old passenger Milena Del Valle and slightly injuring her husband Angel Del Valle, who was driving.

And that doesn't even mention the flooding and previous falling debris. Good thing CNN's on it:

There have been water leaks and at least one incident when dirt and debris from an air shaft fell onto cars.

[Quick aside here; it looks like Chicago's subway system may be it's own Danger Hole. Or, as Kevin Whited would call it, "Danger Train Hole." And is it just a coincidence that both Danger Hole incidents happened on the same day as the terrorist attacks on Mumbai's train system?]
