The National Transportation Safety Board’s hearing into the deadly 2006 ceiling collapse in a Boston Interstate 90 tunnel portal appears to be the catalyst for a flurry of related action. A state criminal investigation into the accident may be crystallizing and officials of some firms involved in the tunnel’s construction are trying to clarify the results of the July 10 hearing. NTSB concluded that fast-set epoxy usage on the tunnel ceiling anchors led to the fatal collapse that killed a 38-year-old local woman.
Officials close to the Central Artery/ Tunnel project confirm a published report that project consultant Bechtel/Parsons Brinckerhoff is being pressured to make a substantial financial settlement in exchange for immunity before the state attorney general releases findings in a criminal investigation into the accident. Those findings were scheduled for release this month.
