The $4.2 million project, which started in January, added a turn lane on each side of the bridge and a second lane on the 285 on-ramps to help traffic flow better.
“Before, you essentially only had half the bridge turning left on 285 east and 285 west,” said Mark McKinnon, a spokesman for the Georgia Department of Transportation, which was in charge of the project because Roswell Road is a state route. “We were able to extend those back well clear of the intersection on the bridge. There’s a lot more storage area for vehicles on the bridge now.”
The bridge currently handles about 43,000 vehicles a day, a number expected to increase to more than 52,000 in 2032. Marietta-based contractor C.W. Matthews conducted the project, which was officially completed Wednesday, its original due date, and “a little” under budget, McKinnon said.
Though the bridge widening is complete, he said commuters may see contractors doing “punch-list work” in the coming days to “go back and fix a small item or two.”
“For the most part, it’s complete and we think it's going to be really good for congestion out there,” McKinnon said. “It’s going to eliminate one of the biggest problems for traffic in that area.”
