The years-long SR 76/US 79 project is a safety and capacity upgrade for the corridor linking Milan in Gibson County with McKenzie in Carroll County.
Fresh Pavement Glows On Infrared Camera
The video, posted to Facebook, captures the warmth radiating off the newly poured asphalt in bright contrast to the cooler surrounding roadway and terrain. According to myTDOT on Facebook, crews are currently laying asphalt on the main stretch from SR 77 to Newsome Road, and most of the project's grading is now complete. The agency captioned the clip with a seasonal nod to the October timing: “No trick, all treats here!”
With the bulk of the main roadway paving underway, the project update notes that crews will next shift their focus to the side roads. That phase would mark a transition from the highway's core corridor to the smaller connecting routes that feed into it, though the dossier's available updates don't spell out a timeline for that shift.
A Years-Long Push Between Milan And McKenzie
TDOT has framed the broader effort as a safety and capacity upgrade for the corridor linking Milan in Gibson County with McKenzie in Carroll County, per the same Facebook update. The corridor has also seen work between SR 77 and Cutlip Lane.
The state's official project page describes a much larger scope on paper: TDOT's project listing says the department is constructing and proposing to construct improvements to SR 76/US 79 in Carroll County, involving widening and realignment of roughly 12.6 miles of existing roadway. A rural modification document tied to the project, found on preprod.tn.gov, lists the work as widening a two-lane road to four lanes with portions on new alignment, carrying a total project cost of $45,048,500.
Side Roads And Past Progress Along The Corridor
Construction along the corridor hasn't been limited to the main highway. A TDOT construction update noted that Clay Farm Road has been closed for utility realignment and road construction, weather permitting, with a detour signed along Newsome Road, according to tn.gov. Separate construction updates from this summer listed ongoing grading, drainage, noise wall, signal, and paving work on US 79/SR 76, according to tn.gov.
The project has notched milestones before. Back in November 2024, tn.gov reported that TDOT opened the newest segment of SR 76/US 79 in Carroll County on November 11 of that year, seven months ahead of its original schedule. A lane-closure update from March 2025 also flagged ongoing grading, drainage, noise wall, signal, and paving work between SR 77 and Cutlip Lane as a source of lane closures along the route, per tn.gov.
For now, the thermal footage offers drivers and nearby residents a visual marker of how far the paving has come, even as the project's side-road phase and full completion timeline remain unaddressed in TDOT's public updates.
