Study: Big Dig Costs to Rise Again--By $100 Mil

BOSTON-An independent estimate of the Big Dig, the massive highway construction project being done here in the heart of the city, further ups the costs of this project that has been plagued by cost overruns.

The estimate was conducted by the accounting firm of Deloitte and Touche and, according to Rita Strazzeri, spokesperson for the Massachusetts Turnpike Authority, is almost the same amount as the internal review conducted by the Authority. “It’s a good sign that they came close together,” she tells GlobeSt.com.

The estimate states that the Big Dig will cost $100 million more than was previously estimated and comes a month after the MTA revealed $300 million in new overruns. The cost for the project is now up to $14.475 billion.
