The Georgia Department of Transportation plans to begin inspection today of the Ga. 53/Dawsonville Highway westbound bridge over the Chattahoochee River portion of Lake Lanier. As part of the work, engineers will use a piece of equipment known as a “snooper” that has a basket and can carry a person under the structure, also known as the Jerry Jackson Bridge. “The snooper looks like a big arm is reaching around then under the bridge,” said Billy Cantrell, district maintenance engineer.
