From TDOT,

Beginning at 9 a.m. on Monday, June 1, crews will close Woodson Drive and Wye Way at the intersection with Alcoa Highway while crews place fill material, install storm drain and utilities, and construct the new roundabout and curbs.

As part of the improvements to Alcoa Highway from Woodson Drive to Cherokee Trail, TDOT is building a new roundabout at Woodson Drive to make the intersection of this essential roadway with the collector road and Wye Way safe and efficient. This location is close to where Woodson Drive connects to Alcoa Highway.

The detour will take drivers to Cherokee Trail and the UT Hospital entrance. It's bad enough they are directing people to Cherokee trail, a skinny, dangerous, steep road, but then they are putting more traffic at the entrance to UT Hospital. Being a local, I'd probably go to Maloney Road. It is a little out of the way, but a much better road. Although, that underpass at Mount Olive School would probably slow down traffic.
