New warning devices will be installed at the historic Concord Road Covered Bridge.
Approval was given by a 5-0 vote on April 23 by the Cobb County Board of Commissioners.
Detection Engineering Technology, Inc. was awarded the $19,540 contract for installation of two more over-height vehicle notification devices, according to Cobb Department of Transportation Director Erica Parish.
To attempt to discourage repeated collisions with warning devices at the bridge, Cobb DOT officials have researched additional warning systems for over-height vehicles.
Installation of these two new over-height vehicle detection devices “will provide effective sequencing of multiple existing warning systems,” Parish said in an April 23 memo to County Manager Rob Hosack.
The new warning devices consist of a traffic signal mast arm with plastic-covered chains hanging down to a height of seven feet, the maximum clearance of the bridge, she said.
Over-height vehicles will hit these new physical hanging warning devices, she explained.
Then drivers will see the existing electronic warning signs identifying the vehicle as over height and instructing them to turn around to avoid damaging the covered bridge, she added.
