The Arkansas Department of Transportation said in a tweet that during a routine bridge inspection, ARDOT found a crack in the I-40 Mississippi River Bridge that requires further investigation, and that that bridge is closed to all traffic until further notice.
ARDOT is currently working with the Tennessee Department of Transportation to make sure the bridge is safe for motorists before it is reopened to any traffic.
Arkansas I-40 eastbound traffic should take I-55 (Exit 5) to cross the Mississippi into Memphis, and Tennessee I-40 westbound traffic should use Exit 4 to cross into Arkansas.
