Definitely look for water moving from one side to the other side of the road either by culvert or one of the small bridges. But there are a some really good spots that don't cross the road. Some of my best trout have come from there. Basically if you look at a spot and think it looks good then give it a try. You never know. Give it a few minutes and then move on. If a spot isn't producing it can turn on later in the day. For me I always take the right on the toll bridge instead of heading straight to Fourchon and work my way towards Grande Isle giving my spots a try along the way.
Not sure how old your kid is but be extremely careful along the road. People fly up and down Hwy 1!!!!
Good Luck!
