The Callahan Tunnel will be shut down Sunday night to allow for the inspection of all 2,800 wall panels, after one of them fell into the roadway Friday night and tied up traffic for several hours, a state transportation official said.
“We’ll physically yank on every panel,” said Frank DePaola, Massachusetts Department of Transportation highway administrator. “We apologize for this inconvenience for people who are traveling to the airport.”

The panels most likely became loose because their metal fasteners are rotting.
The panels, 4 feet by 9 feet and weighing about 100 pounds, were installed about 1990. Because of their age, the tunnel is inspected once every three months, DePaola said.
"Rotting" means rusting. If they "yank every panel", can they install STAINLESS STEEL fasteners?
