KNOXVILLE, Tenn. — If you are headed to the airport Wednesday night, you might want to allow a little extra time.

TDOT said that there will intermittent closures of Alcoa Highway at Airport Hotel Drive between 8:30 and 9 p.m. both evenings. That's just past the airport if you are coming from Knoxville, so you may want to leave early just in case.

Contractors will be relocating power lines in that area, and when they need to pull the lead ropes and power lines across the highway, they will need to shut Alcoa Hwy. down for about 15 minutes. They will be placing a total of four lanes each night.
