April 19, 2012 JOHNS CREEK, Ga. — The McGinnis Ferry Road bridge over the Chattahoochee River is slated for completion over the summer.
Georgia Department of Transportation District 1 Communications Officer Teri Pope said construction on the bridge began Jan. 12, 2010. The horizontal beams were laid across the river over the weekend.
"That's a very exciting milestone event on a bridge project," she said.
Pope then described the process of building a bridge. The vertical caissons rise out of the river and the horizontal beams are laid on top to support the driving surface. Steel deck pans are laid between the beams to bind the structure together. After the pans are in place, work begins on the driving surface. Steel rebar is laid in a grid and concrete is poured; the rebar's purpose is to strengthen the concrete.
Once the concrete is poured, it will cure. Then GDOT will texture it and lay the stripes dividing the driving lanes from the shoulder and each other.
Pope explained that in addition to constructing the bridge, there is still work to be done on McGinnis Ferry Road itself. Only one open lane leaves Johns Creek, but two enter it.
"We've got to get traffic lined up with the new bridge," she said.
When it is finished, the road will have two lanes on either side divided by a grassy median, just like the rest of McGinnis Ferry Road.
Pope said GDOT is getting close, with an anticipated completion date over the summer. The official completion date is still being negotiated with contractor CW Matthews of Marietta.
Pope thanked the community for its patience, but warned drivers to slow down in the work zone to protect themselves and workers from injury. All fines for vehicular violations are doubled in work zones.
The combined project is 1.1 miles long and will cost $7.6 million. Like almost every other GDOT project, it is funded by federal and state gas tax collections. The federal gas tax funds 80 percent of the project, while the state gas tax funds 20 percent.
"First and foremost, I'm very excited that the bridge will be completed," said Mayor Mike Bodker.
He said this is the final piece of the puzzle in clearing up the eastbound congestion building up since McGinnis Ferry Road was widened.
"This will make driving between Gwinnett and Johns Creek much easier," he said. View images.Editor, Johns Creek Herald
