The Lake Pontchartrain Causeway turned into a commuter's nightmare Tuesday morning after at least six crashes led to multiple injuries and damaged vehicles strewn across the traffic lanes that could take hours to remove.

More than 24 hours after a massive pileup on the Lake Pontchartrain Causeway, officials have a better idea on the extent of the damage.

The Lake Pontchartrain Causeway in southeastern Louisiana is expected to fully reopen Tuesday night after dense fog contributed to multiple crashes Tuesday morning, bringing traffic to a halt and trapping drivers on the world's longest continuous bridge over water for several hours.
