A contract worker for TDOT was killed on Thursday morning near Flat Top Mountain.
The accident happened when a tractor trailer overturned on Highway 111.
TODT officials said a crew has been paving a section of Highway 111. Crews were preparing to work around 10 a.m. when a truck hauling coal overturned near where a contractor was standing by his truck.
TDOT was also dealing with an incident in Polk County where a truck went off into the Ocoee River. A tanker truck hauling fuel left the roadway Tuesday at about 6 p.m..
It spilled thousands of gallons of gasoline and diesel, and the accident closed the highway for nearly 30 hours. The road was opened to one late at 10:45 p.m. on Wednesday.
Officials on Thursday said US 64 in Polk County was still down to one lane at the site of the crash. The environmental contractor working on the cleanup will reassess progress on Friday.
Officials said, "If they do not feel that they have made sufficient progress, they will work through the weekend. During their work, the road will continue to be down to one lane. Flaggers will assist with traffic control. So far, traffic has been moving through the area smoothly with very little delay."
