NICK EICHER, HOST: Back in Civil War days, the Concord Covered Bridge in Cobb County, Georgia, burned down.
The locals rebuilt it in 1872, but now it faces a modern threat: GPS.
Drivers who are only following on-screen directions appear to be missing crucial warning signs, like this one: the bridge entrance is only 7-feet high.
Since December, five vehicles have smashed into a 7-foot warning beam placed immediately in front of the bridge.
But just as technology is threatening the bridge, technology also promises to save it.
Highway officials have installed a radar system that flashes a much-earlier warning when approaching vehicles are too tall to cross.
It’s The World and Everything in It.
