The bridge was built to replace a ferry. It's modern, but at least we can take comfort in knowing that no historic bridges were harmed in the making of this one.

At 12,883 feet in length, this bridge is the longest cable-stayed bridge in the Western Hemisphere, but it's 1,583ft main span is only the second longest in the western hemisphere.

According to the TIMED page, it is cable-stayed and not wire suspension. It is, however, the longest cable-stayed in the western hemisphere.

Is this bridge wire suspension or cable stayed? It has been said for the past few decades that a wire suspension is only necessary for real long spans. With that, most new constructions across rivers like Mississippi wind up being cable stayed. If this new bridge is a wire suspension, that would be more interesting and look better than a cable stayed.

The flooding of the Mississippi brought an early end to ferry traffic, and now this bridge is open. There are still minor things that need to be finished but it is now carrying traffic.

Cliff - The now-open bridge carries LA-10 across the Mississippi. There are plans to eventually expand the highway to 4 lanes all the way to Bogalusa. Hopefully they'll pair it with an elevated section over the Morganza Spillway, a bridge over the Atchafalaya, and a new interchange with I-49.

What route will utilize this bridge? LA 1 or LA 10 or just local traffic? Is this part of the proposed extension of I-49?
