Contractors working for the Georgia Department of Transportation (GDOT) will continue construction on the I-16/I-75 Interchange Improvement Project in Macon-Bibb County from November 21 to November 28, 2025. No lane closures are planned during this period, but maintenance and clean-up activities will proceed as scheduled, depending on weather and site conditions.
A long-term traffic shift remains in place through January 2026. Southbound traffic on I-75 heading to I-16 eastbound is being rerouted onto new left lanes of I-16 eastbound. This shift restricts access to the Spring Street/Exit 1A ramp, requiring drivers to use Martin Luther King Jr. Boulevard instead. Northbound traffic from Hardeman Avenue toward I-16 eastbound is also using new left lanes but retains full access to Spring Street/Exit 1A. Signage and lane striping are present to guide drivers through these changes. The traffic shifts allow crews to construct pedestrian bridges over the Ocmulgee River.
Some ongoing closures continue in the area. The far right lane of Spring Street at the I-16 westbound on-ramp and the right-hand on-ramp itself remain closed for several months, with access relocated to the far left lane.
For phases four and five, work includes constructing bridge substructures and superstructures for entrance and exit ramps at Spring Street, building a new Second Street bridge substructure, pouring concrete for new bridge decks on I-16 eastbound, continuing demolition of an old ramp to I-16 eastbound, installing retaining walls along both directions of I-75, and placing drainage structures throughout the project zone.
In phases two and three along I-75 from Hardeman Avenue to I-16 eastbound, crews are repairing sidewalks with ADA-compliant ramps, installing street lighting, and building sound barriers along both sides of the interstate.
Phase one focuses on evaluating remaining work between the split at I-16/I-75 and Martin Luther King Jr. Boulevard exit.
The overall project represents a $500 million investment aimed at improving safety and mobility by widening interstates, upgrading ramps and bridges, adding collector-distributor lanes, enhancing drainage systems, and providing better infrastructure for local commuters as well as regional freight movement. Work is being completed in seven design-and-construction phases expected to last until 2030.
Motorists are advised that schedules may change due to weather or other factors; delays should be expected while traveling through work zones. GDOT recommends checking real-time updates by calling 511 or visiting 511ga.org before traveling.
