Contractors working for the Georgia Department of Transportation (GDOT) will continue construction on the I-16/I-75 Interchange Improvement Project in Macon-Bibb from January 9 to January 16, 2026, as weather and site conditions allow.
Nightly lane closures are scheduled from Monday, January 12 through Friday, January 16, between 9 p.m. and 5 a.m. These include a single lane closure on Spring Street near the overpass bridge for lighting installation and a single lane closure on the Second Street bridge while crews install deck drains and remove equipment. Traffic in these areas will be slowed for safety.
A long-term traffic shift is ongoing through January 2026 as part of the project. Southbound I-75 traffic heading to eastbound I-16 will be directed onto new left lanes of I-16 eastbound, with restricted access to the Spring Street/Exit 1A ramp. Drivers will need to use Martin Luther King Jr. Boulevard instead. Northbound I-75 traffic toward eastbound I-16 will also use new left lanes but can exit at Spring Street as usual. Roadside signs and lane striping are in place to guide drivers through these changes. These shifts allow construction of pedestrian bridges over the Ocmulgee River.
Several closures remain in effect for several months: Spring Street’s far right lane at the I-16 westbound on-ramp and the right-hand on-ramp itself are closed; access has been relocated to the far left lane.
Construction activities planned for this period include vegetation clearing along I-75 from the interchange to Pierce Avenue, installation of erosion control devices, continued work on multiple bridge substructures and superstructures along both interstates, demolition of existing ramps, building new retaining walls, installing drainage systems, sidewalk repairs and ADA-compliant ramps, street lighting installation along I-75, sound and visual wall construction, and evaluation of remaining work items near Martin Luther King Jr. Boulevard.
The $620 million megaproject aims to widen and reconstruct sections of both interstates and their interchange in seven phases extending through 2030. When completed, improvements such as collector-distributor lanes (CD lanes), additional interstate lanes, upgraded ramps and bridges—11 bridges in total—new walls, better drainage systems and more are expected to improve safety and mobility for local commuters as well as regional travelers moving freight across Georgia’s southern coast and beyond.
Motorists should expect delays due to ongoing work zones during this period. The GDOT advises caution when traveling through affected areas and recommends checking real-time updates via phone at 511 or online at https://511ga.org/.
“The Georgia Department of Transportation plans, constructs and maintains Georgia’s state and federal highways. We’re involved in bridge, waterway, public transit, rail, general aviation, bike and pedestrian programs. And we help local governments maintain their roads. Georgia DOT and its nearly 4,000 employees are committed to delivering a transportation system focused on innovation, safety, sustainability and mobility. The Department’s vision is to boost Georgia’s competitiveness through leadership in transportation,” according to GDOT.
