Likewise, the points of attachment of the cables on the beam of the I. A cable-stayed bridge, one of the most modern bridges, consists of a continuous strong beam girder with one or One can calculate the length of the remaining cables more pillars or towers in the middle. A typical cable-stayed bridge is a continuous girder with one or two towers erected above piers in the middle of the When building a cable-stayed bridge, to figure out how span. From these piers, cables are attached diagonally to the long the cables need to be, engineers either use scale girder to provide additional support.

I think this would be a helpful part of the article. I'd be happy to draw up a hand sketch if someone else has the technology to turn it into a computer-drawn diagram. For highway and rail bridges, they have been used at spans as low as about 75m, but start coming into their own above about m, where girder bridges can be very expensive.

They then range up to about 1km, although there are obviously very few cable-stayed bridges with spans approaching that. It has been stated that spans up to about 1. It also added a picture. Looking at the picture, I see an extradosed bridge.

The towers are short and the cables are less than 45 degrees meaning that they impart more horizontal force than vertical support. I think that either a refernce is needed or the statement needs to be revised. Is the Donzere-Mondragon a modern cable-stayed bridge?

It isn't mentioned in Walther's book "Cable-stayed bridges", which describes the Stromsund bridge as "the first modern steel cable stayed bridge". From that, and looking at structurae, I'd guess that the Donzere-Mondragon bridge could be the first modern concrete cable stayed bridge. I don't think the cable angle is entirely relevant - one of the features of an extradosed bridge is that essentially it's a post-tensioned bridge in which the post-tensioning cables are brought above the line of the deck hence the term "extrados", normally referring to the top surface of an arch bridge, but here the top surface of any bridge.

While this might be true of Donzere-Mondragon, it's only a subset of the cable-stayed bridge type. I'll report back once I've looked through some other sources. There's lots more I could add if I get time, but that will do for now.

I've undone his change. Without any intent to be confrontational, if it's not cable-stayed, what is it?

It's not a suspension bridge formed from or hanging from a catenary rope, cable, or chain and it's clearly not a beam, cantilever, arch, or truss bridge. That could, however, have very well have been the reason the Howe trusses were added along the top of the deck, as shown in the HAER drawings, but according to the HAER notes the bridge was in service for 9 years before that was done and the original deck design was clearly not intended to have any vertical stiffness on its own.

To say that it wasn't a cable-stayed bridge in its original design and during its first 9 years of service, at least, seems to be splitting hairs.
