Does anyone know how high the interstate bridge is over the river? This could be a major hindrance to relief efforts in the short term and to travel through this region in the long term.
I was just looking at a map. The Tangipahoa River goes under I-55 about five miles down from this dam.

It is low. You don’t get into high, solid bridges until you get into the swampland south of Hammond
When I-55 passes over the Tangi River it is basically just a minor over pass typically like a bridge found on any Interstate passing over a creak or a small stream - there is no major structure just a typical over pass at the same elevation as the rest of the interstate. It is hard to see the actual river during normal times.
