Ants on an ant hill

A new bridge is in the process of being constructed over the interstate at Atlanta's 14th Street. Making room for the new structure's center support column required the moving of seven interstate lanes approximately 60 ft to the west. The construction site was located at the north end of the downtown connector, where I-75 and I-85 come together, with the road-work portion having been approximately 1,500 yd in length. This project scope also included lowering the grade of about 700 ft of the seven southbound lanes by 30 in. at the maximum point to take a "hump" out of the interstate. To accomplish this, the company had to cut just over 5 ft deep at the peak of the cut. To handle traffic flow, two lanes of I-75 were moved over on the weekend of Aug. 15 to new pavement previously built behind a barrier wall. I-85 traffic used a detour along the old Techwood Drive ramp during the Labor Day Weekend, when the main thrust of the project took place, beginning at 9 p.m. Aug. 29. The company would be assessed a $10,000-per-hour penalty should they be unable to finish and be off the road by 5 a.m. Sep. 2.
