Traffic patterns on I-16 and I-75 in Macon-Bibb will change between December 19 and 26, 2025, as part of the ongoing I-16/I-75 Interchange Improvement Project. Southbound traffic on I-75 from just south of Pierce Avenue to I-16 eastbound will be shifted onto new left lanes of I-16 eastbound. This change will limit access to the Spring Street/Exit 1A ramp, with drivers being detoured to Martin Luther King Jr. Boulevard for exits.
For northbound traffic on I-75 from just north of Hardeman Avenue to I-16 eastbound, vehicles will also shift onto new left lanes of I-16 eastbound. From this direction, drivers can still exit at Spring Street/Exit 1A as usual.
Signage and lane striping are in place to guide motorists through these new configurations. The shifts are necessary for crews to continue work on pedestrian bridges over the Ocmulgee River.
Several long-term closures remain in effect. The far right lane of Spring Street at the I-16 westbound on-ramp and the right-hand on-ramp to I-16 westbound are closed for several months. The Spring Street on-ramp to I-16 westbound has been relocated to the far left lane.
During the week of December 19–26, construction activities will include continued work on bridge substructures and superstructures for various ramps and bridges along both interstates, pouring bridge deck spans, constructing retaining walls, installing drainage structures, repairing sidewalks and ADA-compliant ramps, installing street lighting, building sound and visual walls along I-75, and evaluating remaining work items near the Martin Luther King Jr. Boulevard exit.
The interchange project is a $620 million effort aimed at widening and reconstructing sections of both highways and their interchange in Macon-Bibb County. It is being completed in seven phases scheduled through 2030. When finished, the project will add collector-distributor lanes, additional interstate lanes, upgraded ramps, improvements to eleven bridges, new walls, enhanced drainage systems, and other upgrades designed to improve safety and mobility for local commuters, businesses, regional travelers, and freight moving throughout Georgia and beyond.
Officials caution that dates may change due to weather or other factors. Motorists should expect delays in work zones and are advised to use caution while traveling through these areas.
