Wall Panels Removed From Boston’s Callahan Tunnel

BOSTON — State transportation officials have decided to take down all 2,800 reflective wall panels from inside the Callahan Tunnel because it’s more cost effective than conducting frequent tests.

The state Transportation Department decided last month that it would conduct quarterly tests on the panels after one 4-foot-by-9-foot, 100-pound panel fell to the road. No cars were struck and no one was hurt. Authorities say the panel fell because fasteners attaching it to the wall had corroded.

State Highway Administrator Frank DePaola told the agency’s board Wednesday that crews have already removed about 75 percent of the panels.

He tells the Boston Herald it would cost just much, if not more, to test the panels than it would to take them down.

The downside is that the tunnel is now darker.

“We have put up message boards asking drivers to use their headlights now as they go through the tunnel because the raw concrete wall is dark and non-reflective,” DePaola said.

    How could a competent engineer fail to specify corrosion resistant or corrosion
    proof fasteners and brackets in an damp underwater application subjected to a
    constant corrosive environment from motor vehicle exhausts? How could galvanic
    corrosion from dissimilar metals not be taken into account? How can an
    Administration allow such an incompetent design to be procured and
    installed?
