Starting Tuesday, part of North Campbell Station Road will be closed for the next three weeks.
This closure is a third of a mile south of Yarnell Road. Drivers can use Yarnell and Lovell Roads as detours, but local access will still be allowed.
Over the next 21 days, crews will be lining up the road for a new bridge project. Knox County plans to reopen that spot on North Campbell Station on Tuesday, December 18.
