Upgrades will be made to the interchange at I-16 and State Route 17 through a partnership between Chatham County and the Georgia Department of Transportation (GDOT). Chatham County will sponser the preliminary engineering and GDOT will manage construction. The project will widen or replace the existing bridge over I-16 and ramps to accommodate additional traffic volumes to keep the interchange functioning at an acceptable level through 2050. Concept design and review of the alternatives is now complete. The divering diamond was determined to be the best option. Preliminary design is underway. Construction is anticipated in 2026.
