-----------------------------------------------


Georgia DOT contractors will close and replace the SR 299 at I-24 bridge in Dade County starting Friday, May 12th at 9:00 p.m. through Monday, May 15th at 5:00 a.m.

Georgia DOT says for the first time it is employing an innovative building method called Accelerated Bridge Construction (ABC) to minimize the project’s impact on the environment and traveling public. This technique will contain the existing bridge removal and new bridge installation within a single weekend (56 hours).

The bridge is the overpass for the I-24 at Exit 169 (SR 299) interchange, located approximately 0.6 miles south of the Georgia/Tennessee state line. Clearly marked detours will reroute travelers around the SR 299 bridge and associated loop ramps. (see map above)

The SR 299 bridge replacement is the debut of the ABC method in Georgia. “Taking care of our bridges is a high priority within the Department,” says Andrew Hoenig, Georgia DOT Senior Project Manager. “Being able to replace a bridge in an accelerated time frame allows us to apply industry innovation and complete the construction much sooner than a standard bridge reconstruction.”
