Inspectors from the Tennessee Department of Transportation will carry out their regular quarterly testing and inspection of the Market Street Bridge downtown on Sunday.
Their work will begin at 8 a.m. with the bridge being closed to traffic.
The drawbridge will be opened as part of the process, officials said in a release.
The bridge should be reopened for use no later than 2 p.m., the release said.
Bad weather or unforeseen circumstances could lead to the inspection being put off to a later date.
