Once considered the longest bridge in the world, its status is being challenged by recent projects in Europe and Asia. Still, the causeway is a marvelous engineering project and a wonder to behold as you drive over it with the blue of the water and the blue of the sky merging in the distance ahead of you. The bridge is 24-miles long, and consists of two parallel decks 80-feet apart each outfitted with two lanes of traffic. The decks are supported by more than 9,000 pilings and joined by seven turnaround zones for emergency vehicles. The Lake Pontchatrain Causeway is a singularly amazing bridge. But it may not be alone for long. A study is underway into whether another bridge is needed to span the lake.

• Lake Pontchatrain is named for the Count de Pontchatrain, Louis XIV's finance minister.
• An average of 30,000 vehicles cross the bridge each day.
• 1995 - A $79,000,000.00 rehabilitation project gets underway. It is expected to be complete in 2006.
