This road gets flooded and disappeared twice a day in France

posada Gua France this 4.3 kilometer stretch of road links the French mainland with island of Norman's here on France's Atlantic coast at first glance  you might think that's not a bad road to drive on wait a few hours and your   opinion will change as the tide comes in and causes the entire route to vanish twice a day this road is underwater and any car that mistimes their crossing is going with it even if you time the tides just right driving this road can be a challenge because it's wet and covered  with seaweed which can make it as slippery as ice
