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
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.
