My understanding is that the diagonal stay cables don't really do anything. They're there because, to be on the safe side, Roebling overdesigned the bridge with them, with the bridge being really a suspension bridge. Aesthetically however, they look really nice. (The main structural problem with the Brooklyn Bridge is that, while the Brooklyn tower is resting on bedrock, the Manhattan tower is only resting on soil/silt...in an area with geological fault lines.)

Steel truss bridges are efficient in their use of materials but they have a downside. Typically trusses are not redundant - if you lose a single truss member than the bridge turns into a mechanism and collapses catastrophically. In contrast, a bridge that carries weight through bending typically has a slower failure mode.

Canada's most important - and probably least well known bridge - is a modern cable stay! The Nipigon River Bridge in northern Ontario; it's the narrowest east-west transportation bottleneck in the whole country. Literally anything driving from anywhere in Eastern Canada to anywhere in Western Canada WILL cross this bridge. Fun fact - Nipigon gets so cold in the winter (something the architects didn't consider properly) that the bridge actually buckled in 2016 while under construction - so all road traffic had to be rerouted through Minnesota, Wisconsin, AND Michigan - adding some 2,800kms to peoples trips.

The Deh Cho bridge is an engineering marvel, because of the extremes of weather and vast quantities of river ice the bridge’s design must account for.

For long spans the issue is height. The tower height is directly related to span, as the span grows, the height of the tower grows at a much quicker rate than a suspension bridge tower would. You hit a point where they get so tall, so large, so much work needed for the foundations, and comically long cables; that suspension bridges become way more economical.

The Queensferry Crossing near Edinburgh has one of these too. The old Forth Road bridge is a suspension bridge (it’s not really used anymore due to it being unsafe) and the original Forth bridge is a Cantilever bridge. It’s interesting to see the different designs all co-existing in one place.

It's also a good example of how span length is affected by the bridge form. For a similar size crossing, the Queensferry crossing requires three towers which dwarf the towers on the Forth Road Bridge. The Forth Road Bridge only has two towers and the suspension style bridge can cover a similar sized gap to the two main spans of the Queensferry Crossing. Obviously the advantage comes to maintenance, it's much easier to change out a few weakened cable stays than it is to replace an entire suspension cable.

i live near the cable stay Clark Bridge in Alton/St. Louis, it was built in 1994. I've always liked that they painted it yellow, it makes it stand out a bit.

The height we can build the towers on both ends determines the max span. With suspension design, the required tower height is usually lower than cable stayed bridge design.

Me: *looks outside* Bridge: sup

One potential advantage of a cable stayed bridge is that it can be designed with one tower, and it does not have to be symmetrical, unlike a conventional suspension bridge. One early cable stayed bridge, the Severinbrücke in Cologne, Germany (1959), has only one tower, and it isn't in the middle, which leaves more of the Rhine River open for the frequent shipping traffic. structurae.net/en/structures/severin-bridge Building two towers and their foundations is a major part of the cost of a suspension bridge, as well as a cable stayed span. Consequently, building a bridge with one tower instead of two saves a lot of money. However, cable-stayed bridge towers are under a lot of bending moment compared to conventional suspension bridges, where most of the load is transferred by the cables to the anchorages. Look at the enormous central anchorage on the west side of the San Francisco-Oakland Bay Bridge, which is really two separate suspension bridges connected by a roadway.

We would also like to remind bridge owners of an anecdote. John Roebling was the design engineer of the Brooklyn Bridge. After the bridge had survived several natural events much more successfully than some others, he was asked why. His response was that, since he did not know what he did not know, he designed the bridge to withstand *six times* his best estimate of the combined static and dynamic loads it might ever have to withstand. We tend, nowadays, to build things cheap. Tall buildings and big bridges should be the two major exceptions to that habit; each should really be designed to last a century. In my humble opinion.

That massive factor of safety was required due to the limitations of structural analysis at the time (extremely limited computational power). Now we have a much more complete understanding of the forces on bridges and so we can reduce the factor of safety. Overbuilding structures to that level would not be financially possible. Infrastructure budgets are already insufficient.

Cable-stay bridges look interesting, but there is something magical about a suspension bridge. In particular, the Verrazzano Narrows is often overlooked though its length and clean lines make it one of the most beautiful in the world. I grew up within sight of it, first in Brooklyn and then in Staten Island, where I saw it rising above the treeline and soaring into the sky.

You showed the Quebec's bridge being the largest Canteliver bridge made by the same engineer who did the Queensferry one in Scotland. Now, if you see the new Champlain bridge in Montreal, this is massive cable-stay one with three beds including the middle one for suburban train lines. It is so impressive and goes extends over 13 km where the St-Lawrence is very wide.

Primarily not having to build giant anchorages for the cables, which enables more spans. For example, a basic suspension bridge has two towers and three spans. The western section of the Bay Bridge near San Francisco is essentially two suspension bridges connected by a shared anchorage (built at high cost on water) and bookended by two at the ends; 4 towers, six spans. A cable stayed bridge in the same location would only require five spans. They're also better suited for railway traffic. The Great Belt bridge in Denmark does not carry trains, thus requiring the construction of a parallel set of tunnels, whilst the Øresund bridge, built around the same time, does.

@@ahqhue The reason Oeresund bridge uses cable-stayed was because they didn't need the span since they already had a tunnel built. The GBB was too long and in an extremely windy area to carry railway, and being the second longest span at the time, it wasn't possible for it to support trains. But I do want to point out that the Tsing Ma bridge in HK does carry high speed rail and a lower freeway, with a main span of 1.4 km, and in a typhoon prone location. It's mainly the affordability and not the flexibility that is an issue, as Cable-Stayed bridges can be almost 3x cheaper at worst and are better for spans below 1km

The only hope I have for old bridge maintenance is that golden gate and Brooklyn are never replaced. At the very least, I’d want them to be replaced by an alternative bridge built hundreds of feet away from the original one (for Brooklyn), or an undersea tunnel built below and beside the old bridge (golden gate), and for the original bridges to remain pedestrian only, and then if that’s not safe enough, then closed to access but maintained just as an icon.
