A major detour awaits many motorists this weekend. From six o’clock tomorrow morning until nine o’clock Sunday night, the Jimmie Davis Bridge across the Red River will be closed.The state Department of Transportation and Development needs to make some repairs to the bridge deck and can’t do it with traffic whizzing by. Motorists who would normally take the Jimmie Davis Bridge will have to use the Shreveport-Barksdale Bridge over the weekend —getting to it on the Bossier side from Barksdale Boulevard or the Arthur Ray Teague Parkway and on the Shreveport side from Youree Drive or the Clyde Fant Parkway. As always, the work will be weather-permitting
