If people don’t enjoy going to see smaller cities, they may wonder why go anywhere other than New Orleans or Baton Rouge when in Southeast Louisiana. There are some towns like Metairie, Hammond, Slidell, and Mandeville, Of course, Metairie isn’t that small of a city, but Mandeville is quite small. Why would anybody want to visit these places that aren’t a main city of Louisiana? However, there is a reason to visit the towns of Metairie and Mandeville in Louisiana. This is especially true if you like to see different bridges.
Metairie and Mandeville are the homes of the ends of the longest bridge in the world. Metairie is home to the southern end of the bridge and Mandeville is home to the northern end of the bridge. This bridge is the Lake Ponchartrain Causeway. It crosses Lake Ponchartrain in Southeast Louisiana.
The Ponchartrain Causeway is two parallel bridges, the longer of which spans 23.87 miles (38.42 km). The bridge spans 1/1000 of earth’s circumference.
More than 9,000 pilings support the two parallel bridges, each of which has two lanes for traffic flow. Over 30,000 cars now drive over the Ponchartrain Causeway every day. The speed limit on the bridge is 65 mph and does not change during day or night times.
The Ponchartrain Causeway was first the idea of Bernard de Mandeville (the founder of Mandeville) who ran a ferry service on Lake Ponchartrain. However, he did not first decide to have two parallel bridges. Those were built more than 30 years after the first construction of the Ponchartrain Causeway.
There is debate among some people whether the Ponchartrain Causeway is actually the longest bridge in the world. However, this has to do with how people say bridges are officially measured. Some say that bridges should be measured by the span while others say it is the total length of the bridge that counts.
The people who advocate the Ponchartrain Causeway as the longest bridge in the world get official support because it is listed in the Guinness Book of World Records as the longest bridge in the world.
Even if people disagree, if you have visited or seen the Ponchartrain Causeway, you can always tell them that it is the longest over water highway in the world. There is no debate about that claim.
Why not visit something different instead of New Orleans if you are going to be in Southeast Louisiana? Visit the longest bridge in the world, the Lake Ponchartrain Causeway!
