Page "Big Dig" Paragraph 28

On September 15, 2004, a major leak in the Interstate 93 north tunnel forced the closure of the tunnel while repairs were conducted.

This also forced the Turnpike Authority to release information regarding its non-disclosure of prior leaks.

A follow-up reported on " extensive " leaks that were more severe than state authorities had previously acknowledged.

The report went on to state that the $ 14. 6 billion tunnel system was riddled with more than 400 leaks.

A Boston Globe report, however, countered that by stating there were nearly 700 leaks in a single section of tunnel beneath South Station.

Turnpike officials also stated that the number of leaks being investigated was down from 1, 000 to 500.
