In southwest Knox County, work is now underway to construct a roundabout at South Northshore Drive and Choto Road.
That intersection used to be a two-way stop. It's now temporarily a four-way stop for safety as crews work.
Knox County Public Works says the roundabout should help with traffic congestion.
The work is supposed to done by the end of September, but the contractor is running behind, which means the roundabout may not be finished until October.
