Contractors for the Georgia Department of Transportation (GDOT) will continue work on the I-16/I-75 Interchange Improvement Project in Macon-Bibb County from March 6 to March 13, 2026. Weather permitting, lane closures and traffic shifts are scheduled during this period.
From Monday, March 9 through Friday, March 13, Spring Street will have nightly lane closures from 9 p.m. to 5 a.m. These closures will allow crews to install lighting under the I-16 bridges.
A long-term traffic shift remains in effect through March 2026. Southbound traffic on I-75 heading to I-16 eastbound is now using newly constructed left lanes of I-16 eastbound. This change restricts access to the Spring Street/Exit 1A exit ramp; drivers must detour past Spring Street and exit at Martin Luther King Jr. Boulevard instead. Northbound I-75 traffic toward I-16 eastbound continues to have normal access to Spring Street/Exit 1A.
Roadside signs and new lane markings are directing drivers through these changes. The traffic shifts are necessary for construction of pedestrian bridges over the Ocmulgee River.
Some ongoing closures remain in place: 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.
Construction activities planned for March 6–13 include pole and line relocations along Riverside Road, continued installation of erosion control devices, bridge superstructure work at multiple locations, pouring bridge deck spans and edge beams, demolition of existing ramps, building new retaining walls along both directions of I-75, drainage system upgrades throughout the project area, sidewalk repairs with ADA-compliant ramps, street lighting installation along I-75, and construction of sound and visual barriers.
The $620 million project aims to widen and reconstruct sections of I-16 and I-75 as well as their interchange in Macon-Bibb County. Work is being completed in seven phases that will extend through 2030. When finished, improvements will include new collector-distributor lanes, additional interstate lanes, upgraded interchanges and ramps, enhancements to eleven bridges, improved drainage systems, and new walls designed for safety and mobility benefits for local commuters as well as regional travelers and freight transporters moving goods across Georgia and beyond.
Motorists are advised that schedules may change due to weather or other factors. Drivers should expect delays and use caution when traveling through construction zones. For up-to-date information about roadwork status or current traffic conditions in Georgia visit https://511ga.org or call 511.
