From Times Wire Reports

Big Dig project managers persuaded the designer of the Interstate 90 connector tunnel ceiling to reduce by half the number of bolts supporting each ceiling hanger, the Boston Globe reported, citing a 1998 memo it obtained. Portions of the Big Dig remain closed after four 3-ton concrete ceiling panels fell in the I-90 connector tunnel and crushed a car on July 10, killing a 38-year-old woman.
