Bigger problems at the Big Dig

| 7/7/2005

Officials have discovered a new problem area in Boston’s Big Dig project. A 1,500-foot section of the Interstate 93 tunnel that runs directly beneath Boston Harbor has a total of 60 defects, according to The Associated Press.

Port officials, using an outside engineering firm for an independent review, found that the North End section of the tunnel is in worse shape than the section of the tunnel that flooded in September 2004.

Big Dig officials told The Boston Globe that the tunnel is structurally sound, but has weaknesses in the walls that could turn into leaks if not repaired soon.

The Big Dig project, which has buried I-93 underneath downtown Boston, has been plagued with numerous leaks that have resulted in other safety hazards, including non-working fire doors.

The problems have, in turn, led to a series of investigations and legislative hearings. The project has so far cost the city $14.6 billion and is said to be the biggest construction project in U.S. history.
