Loose panels removed from Callahan Tunnel

Urgent scrutiny inside Callahan; 117 pieces gone, travel called safe

A state highway crew removed 117 loose panels from the walls of the Callahan Tunnel — each one bigger than a king-sized bed — late Sunday and early Monday, following an emergency inspection after a panel fell into the roadway late last week, the state’s top highway official said.

Three dozen workers pulled on every one of the 2,400 enamel-coated metal panels that line the roughly mile-long tunnel beneath Boston Harbor, after corrosion in unseen support brackets caused a panel to pop off Friday evening, said Frank DePaola, highway administrator for the Department of Transportation.
