Washington, DC -- The National Transportation Safety Board will hold a public Board meeting on Tuesday, July 10, 2007, at 9:30 a.m., in its Board Room and Conference Center, 429 L'Enfant Plaza, S.W., Washington, DC.

There is one item on the agenda:

On July 10, 2006, a passenger car was traveling eastbound in the Interstate 90 (I-90) connector tunnel in Boston, Massachusetts, en route to Logan International Airport. As the car approached the end of the I-90 connector tunnel, a section of the tunnel's suspended concrete ceiling became detached from the tunnel roof and fell onto the vehicle. Concrete panels from the ceiling crushed the right side of the vehicle roof as the car came to rest against the north wall of the tunnel. The passenger was fatally injured and the driver had minor injuries. A total of about 26 tons of concrete and associated suspension hardware fell onto the vehicle and the roadway.
