The $132.6 million improvement project just north of the Georgia state line at the Interstate 75-Interstate 24 interchange - otherwise known as the "Split" - is on track for completion by summer 2021 as some of the most significant features of the redesign begin to take shape.

Marietta, Georgia,-based C.W. Matthews Co. is working to complete new ramps and a new leg of I-75 to switch traffic onto its new alignment this fall, Tennessee Department of Transportation spokeswoman Jennifer Flynn said.

"This will allow construction of the remaining structures and ramps in the spring and summer of 2021 with traffic in its final alignment soon afterward," Flynn said.

More than 100,000 vehicles a day travel the interchange, known for its daily backups, outdated merge lanes and frequent crashes.
