Lane closures and traffic shifts are set to continue on the I-16/I-75 Interchange Improvement Project in Macon-Bibb from February 13 to 20, 2026. The project includes installing lighting under the Spring Street Bridge and removing overhangs.
A long-term traffic shift will remain in effect through February 2026. Drivers traveling southbound on I-75 toward I-16 eastbound will use newly constructed left lanes of I-16 eastbound. This change restricts access to the I-16 eastbound exit ramp at Spring Street/Exit 1A, requiring motorists to detour past Spring Street and exit at Martin Luther King Jr. Boulevard. Northbound drivers on I-75 from just north of Hardeman Avenue heading to I-16 eastbound will also shift onto new left lanes but retain full access to the Spring Street/Exit 1A ramp.
Roadside signs and lane markings are being used to guide drivers through these new configurations. These shifts allow construction crews to build pedestrian bridges over the Ocmulgee River.
Several ongoing closures continue, including 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 moved to the far left lane.
Construction activities planned for February 13–20 include relocating poles and lines along Riverside Road, installing erosion control devices, building bridge substructures and superstructures for entrance and exit ramps, pouring concrete for new bridge decks, constructing retaining walls along both directions of I-75, installing drainage systems throughout the area, repairing sidewalks with ADA-compliant ramps, installing street lighting along I-75, constructing sound and visual walls, and evaluating remaining work items near Martin Luther King Jr. Boulevard.
The $620 million project aims to improve safety and mobility by widening and reconstructing sections of both interstates as well as their interchange. Work is divided into seven phases expected to continue through 2030. Upon completion, commuters can expect additional interstate lanes, new collector-distributor lanes, upgraded ramps, improvements to eleven bridges, enhanced drainage systems, new walls for noise reduction or aesthetics, and better infrastructure for local businesses and freight moving between Georgia’s southern coast and other U.S. destinations.
Officials advise that construction schedules may change due to weather or other unforeseen circumstances. Motorists should anticipate delays in work zones and are urged to drive carefully at reduced speeds.
