Project under renewed fire

Massachusetts State Auditor A. Joseph DeNucci has issued a report claiming that the Central Artery/Tunnel project in Boston, MA, suffered from design flaws which endangered worker safety and which unnecessarily raised costs. The auditor identified the problem as a leak in the sunken tube tunnel and the improper welding of the tubes' internal stiffening ribs. To correct the defect, design changes and rewelding would have to be performed, at a cost of $626,000.
