Here's a video on how they kinda made it.

Kathy: 125,795 feet (total length of bridge) = 23.8 miles.

How many miles long is the bridge?

Having been born and raised in Metaire, LA, as a child, 7 yrs. old. I can remember just waiting for "The Causeway" to open. On a Sunday "outing", the family packed into the car for our first crossing. What a wonderful memory. When we got to the Northshore, we turned around and headed for home. Pls realize that at that time Mandeville was almost non-existant, and Covington was just a speck on the map.

When the second span was opened, now having a driver's license, I was one of the first to cross. Oh, how the memories flood back (no pun intended). Just a penny for every time I made the crossing!

What brought this on, I received an e-mail that claimed that the Donghai Bridge in China is the longest bridge in the world at 32.5km (20.19 mi.---if my conversion factor is correct). That leaves it approx. 3 miles short of our beloved bridges.

I cross this bridge northbound and southbound every Wednesday and Saturday for my horseback riding lesson. It is an engineering marvel!! I have crossed so many times it seems like it takes no time at all to get across to me. If it's your first couple of times traveling across it it seems long.

I live in Baton Rouge so we never take this route. But I am proud to have the worlds longest bride in my state.

It's great, I was in New Orleans but I don't have a expirience traveling across this bridge, I think is so borred,water at both sides, but this thing made me think in how great can be the humans.

How do u build this bridge

How do u build thsi bridge

We traveled across that bridge northbound in 1995. As far as current bridge(s!) go legnthwise, this one takes the proverbial cake. There are five nacvigation humps (cue that overplayed but still very catchy "Black Eyed Peas" song hit): going northbound as did we (my parents and I):

a) nad b) two small fixed prestressed-concrete spans, a larger hump, anotbher smaller "hump",and then the drawbruidge that si pciutred above several times.

Glad to have found this site.

This bridge is sweet! :)<---(this was supposed to be a smilly face) how long did it take y'all, and how ya do it? It makes me wonder where we got the tecnology, time, and material to do things like this. Anyways, I'll find time later to wonder. This is Kendra Miller from Amarillo Texas wishing New Orleans luck. I wish my group had more time than we did to help y'all out. Bye.

The only thing i wonder about the Causeway Bridge is how long did it take to build it and how'd y'all do it?

The Twin Spans (I-10 connecting Slidell to New Orleans East) has been totally destroyed. Huge sections missing; the westbound lane now looks like a huge dotted line.

The southbound span of the Causeway suffered some damage at the connection to south shore. This is in the process of being repaired quickly. The northbound span of the Causeway is undamaged however, carrying emergency traffic only in both directions.

From what I can gather, this bridge has suffered some damage from Hurricane Katrina, but not nearly as extensive as the I-10 bridge over Lake Pontchartrain east of New Orleans. If anybody has more information, please post a comment here.
