"The US Department of Transportation's inspector general has drafted an internal memo that says the Big Dig's cost may rise by tens of millions of dollars, according to state, industry, and federal officials.

US Representative Michael E. Capuano, a Somerville Democrat who spoke to federal officials about the memo's contents Thursday, said no one should be surprised that the cost may rise, given its history.

"We're being told the concern is less than $100 million," he said. "That's a lot of money, but in the scheme of things, it's not huge in relation to a $14 billion project."
