Project Details

The $90 million 14th Street Bridge Replacement, designed to relieve congestion at the 14th Street and I-85/I-75 Interchange, replaced the existing bridge over the Downtown Connector in Midtown Atlanta and constructed two new exit ramps; southbound to 10th Street, and northbound to 17th Street. The replacement of the 14th Street Bridge consisted of a new structure with forty-six 174-foot-long concrete beams spanning the Downtown Connector. Utilities occupying the existing bridge were relocated to a 72-inch-diameter tunnel, also constructed as part of this project. Located in downtown Atlanta on one of the most congested roadways in the area, this project presented unique traffic management challenges. Several detours were required, including a complete detour of I-75/I-85 over a Labor Day weekend, to provide safety for the traveling public and to allow accelerated construction while minimizing impacts to motorists.

As the prime contractor, CWM provided the overall project management in addition to self-performing the majority of the construction elements of the project. The project presented unique challenges, the most significant being opening the new bridge within 570 calendar days of shutting 14th Street down. On September 3, 2009 CWM opened the 14th Street Bridge approximately 100 days early. The project remained ahead of schedule and was completed before the May 31, 2010 fixed completion date.
