Construction work on the I-16/I-75 Interchange Improvement Project in Macon-Bibb will continue with several lane closures and traffic shifts starting December 17, 2025. According to the Georgia Department of Transportation (GDOT), contractors will close the right lane of I-16 westbound between milepost 2 and milepost 1 from December 17 through December 19, nightly from 9:00 p.m. to 5:00 a.m., for utility structure work.
A long-term traffic shift is planned through January 2026. Southbound drivers on I-75 heading to I-16 eastbound will be redirected onto new left lanes of I-16 eastbound, which restricts access to the Spring Street/Exit 1A ramp. Traffic will be detoured past Spring Street to exit at Martin Luther King Jr. Boulevard. Northbound drivers on I-75 heading to I-16 eastbound will also shift onto new left lanes but retain full access to Spring Street/Exit 1A.
Roadside signs and new lane markings are being installed to guide motorists through these changes. GDOT states that these shifts are necessary for crews constructing pedestrian bridges over the Ocmulgee River.
Ongoing closures include Spring Street’s far right lane at the I-16 westbound on-ramp and the right-hand on-ramp itself, both closed for several months. The Spring Street on-ramp to I-16 westbound has been relocated to the far left lane.
Construction activities scheduled for December 12–19 include bridge substructure and superstructure work, installation of drainage structures, sidewalk repairs, ADA-compliant ramps, street lighting installation along I-75, and construction of sound and visual walls.
The project is described as a $620 million safety and mobility initiative designed to widen and reconstruct sections of I-16, I-75, and their interchange in Macon-Bibb County. The project is being completed in seven phases with an expected completion date in 2030. Once finished, it aims to provide improved mobility for local commuters, regional travelers, businesses, and commercial freight across Georgia.
GDOT advises that dates may change due to weather or other factors. Motorists should expect delays and exercise caution while traveling through work zones. Real-time updates are available by calling 511 or visiting https://511ga.org/.
