The Louisiana Department of Transportation and Development has closed the Hwy 1 bridge over Caddo Lake in Mooringsport for minor deck patching.  The bridge is expected to re-open sometime next week.  While the bridge is closed, traffic will be detoured via Highways 169 and 538 through the town of Mooringsport.  DOTD asks that motorists please be patient; drive with caution through the construction site; and be on the lookout for work crews and their equipment.
