BOSTON, MA - March 11, 2014 - The 53-year-old Callahan Tunnel was closed shortly after Christmas 2013 for a multi-million dollar renovation project. The floor had badly deteriorated, and after a wall panel fell in 2012, many more were soon discovered to be defective. Because the main thruway to East Boston and Logan International Airport carries 30,000 cars a day, many drivers and area businesses were concerned a three month closure would cause massive traffic problems and delays.
