Construction remains behind schedule on the $161.6 million second phase of Chattanooga’s monstrous road-building project, the Interstate 75/Interstate 24 interchange at the Tennessee-Georgia state line. Work will continue into 2026, months beyond the original targeted late-2025 finish date.
Over the summer, a new finish line was reset to spring 2026, and both halves of the project — I-24 and I-75 — appear to be on course, according to state officials.
I-24 is largely complete as the year comes to a close, but state Department of Transportation reports show some paving, drainage and noise wall work remains as the contractor, Charleston, Tennessee-based Wright Brothers Construction Co., attends to final details.
“All lanes and ramps are now open on I-24,” agency spokesperson Gracie Shamblin said in an email. “The remaining work to be completed by spring of 2026 includes milling and paving North Terrace and South Terrace, texture coating bridges, retaining walls and noise walls, and final pavement markings on I-24.”
