MACON, Georgia (41NBC/WMGT) – The Georgia Department of Transportation (GDOT) has announced overnight lane closures and traffic shifts for the I-16/I-75 Interchange Improvement Project in Macon from July 26 to August 2.

Contractors will work on various construction activities, impacting traffic flow in the area.

Starting Monday, July 29, through Friday, August 2, from 10 p.m. to 5 a.m., one right lane on I-75 exit ramps to I-16 eastbound and westbound will be closed. Emergency vehicles will slow traffic through these closures.

On Thursday, August 1, from 10 p.m. to 5 a.m., I-16 eastbound traffic will shift left onto two newly constructed lanes between Spring Street and Martin Luther King, Jr. Boulevard/Coliseum Drive.

Long-term closures continue on Webb Street for concrete pavement work at Walnut Street, with traffic detoured to Hudson Street and Orchard Avenue. Additionally, the far right lane of I-75 northbound at the Georgia 19/Georgia Avenue exit (exit 164) remains closed for several months. Spring Street’s far right lane at the I-16 westbound on-ramp and the right-hand on-ramp to I-16 westbound are also closed for several months, with the on-ramp relocated to the far left lane.

Motorists are advised to expect delays, exercise caution and reduce speed through work zones.
