Thanks, Laman! I'll check this out on the map. I appreciate your advice!
Ok with that definition of big bridge than you will probably want to avoid I-10 going into NO from Slidell, fair amount of water to pass over there, and you definitely do not want stay at the state parks south Covington and use the Causeway lots and lots of water that way. The only way to get to NO without going over some type of long water crossing would be to go all the way BR on I-12 than back south on I-10 than about Gonzales get off 1-10 go a few miles west get on Hwy 61 south which then will bring you into the Kenner, Metarie, NO.. There is a KOA in Kenner close to the airport.
