And mine as well.
One thing to be thankful for: at that point of the river (which is close to the source), it wasn't that high up. The larger bridges down near the mouth of the river are three times higher; if one of those fails, the casualty toll would be much greater.
We have a lot of old bridges here; the Huey P. Long bridge over the Mississippi is a major highway (US 90) and railroad bridge that's 72 years old, and crossing it scares the heck out of me. It's getting a major upgrade as we speak (they are widening the roadway, which currently has 2 9-foot lanes in each direction without shoulders; they are outside of the truss structure of the railway portion of the main span, as if it were an afterthought). They are going to add trusses over the roadways and widen them to 3 11-foot lanes, with left and right shoulders.
Bad as that sounds, there's the Twin Span bridge that runs from the New Orleans suburb of Slidell to eastern New Orleans. It was badly damaged by Katrina, and they have temporary steel roadways in place of the concrete sections that were knocked off by the storm surge. The speed limit is 45 MPH, and heavy trucks are not allowed, but people routinely speed and weight restrictions are ignored. I hope and pray that the new $800 million bridge they are building to replace it is finished before the erector-set falls apart.
