A big traffic headache in Bossier Parish. The Dogwood Trail bridge off Stockwell Road at the western entrance of the Dogwood Subdivision has been closed. Parish Public Safety Director Sammy Halphen says a couple of bridge pilings are showing signs of stress and need to be replaced. Emergency repairs are expected to be completed by Friday evening. In the meantime, motorists entering and leaving the Dogwood Subdivision will have to use the eastern entrance off Bellevue Road.
