The Cable Stayed Bridge

The cabled stayed bridge. When done right, it can really transform a skyline and especially look dramatic at night. Under certain conditions, it costs less to build and maintain than a suspension bridge, something to do with maximum road segment length. But it seems many of these projects are plagued with cost overruns. Rusted supports, salt water eating away. If they're supposed to save money, you wouldn't be able to tell based on news headlines. See eastern segment of the Bay Bridge.

If you travel around the world and return home only to see none, you wonder where are my taxes going? Why isn't the infrastructure being updated? Of course it makes no sense to tear down an old bridge and put up a new one just for the sake of it, but NYC, for example, has some pretty old, ugly looking bridges that must cost a pretty penny to maintain. The pigeon droppings alone costs a substantial amount to clean. The Williamsburg. The Manhattan. They just look... old.

The first cable stayed bridge in the US was built in Washington in the late 70s. Tampa has a stunning one. Boston's was finished 13 years ago. The one in Delaware is over 20 years old. Oakland has a new bridge to rival the GG. There are about 30 in the US. There are at least 60 in China alone and there are some stunning ones around the world. One of the bridges below is Calatrava's, but his projects tend to go over budget.

The NYC metro area is finally getting two. There are currently two in existence, but they're pedestrian bridges, at Rockefeller University and the Intrepid, that's it. You have the new Goethels and the Tappan Zee replacement, which 44 fast tracked because the TPZ was literally falling apart with holes and way over its 50 year shelf life and built to bear a lighter load than it does now. I guess that's not uncommon, we wait until the last minute or an accident to do something.

Who knows how much the final tally will be, but at least it's a sign we're updating our infrastructure. The new TPZ (The New NY Bridge? Hope it gets a more original name) has a pedestrian roadway, you'll finally be able to cross the Hudson on foot or bike from Nyack to Tarrytown. For 4 billion, there better be one.

A fascination of yours, or just something that happened to pique your interest today?

The first, find them interesting, bridges/tunnels, and use them all the time, by car, bicycle and foot. Also did the Lincoln Tunnel fun run (5K) and cycle across the GW. Infrastructure is sexy :-D

Cool. I didn't know what the new Goethals Bridge is going to look like when it is completed. Every time I drive on it I always think that's got to be a pretty cool project to work on.

These bridges are 16 and 12 years old respectively:

The Oresund Bridge - connects Denmark to Sweden. Toll? Around $50+ US. You definitely want to buy into the subscription plan, which cuts it in half.

Millau Viaduct in France - Toll is a more reasonable $10.

Fun fact: the Brooklyn Bridge is actually a hybrid suspension/cable-stay bridge.

Another fun fact: I'm also currently selling it. PM me for more info.

Nice try, buddy. I learned about this scam in my Adulting class.

Another one: You used to be able to sneak in and walk up the cable span to the top of the suspension tower if you're not afraid of heights. Going up isn't too bad, going down, when you see what's below you, stress. Then 9/11 happened.

Here's an image of the Sunshine Skyway that spans Tampa Bay and was referred to in the OP. It is pretty cool at night.

It was rebuilt after a tragic event in 1980. Don't know how much news it made in the rest of the country, but for those of us who traveled the bridge and lived in the area, it was very sad...

The Roebling Bridge here in Cincinnati was the unofficial test run for the Brooklyn Bridge; note their similarity.

I've been a part of the design team for 2 cable stayed structures.  Pomeroy-Mason and Ironton-Russell, both over the Ohio River, and both using a similar design has the Cooper River shown earlier.  Long span bridge design is by nature "cutting edge", but bridge owners do not like to be cutting edge for fear of maintenance problems.  A perfect example is the East section of the Bay Bridge.  The self anchoring design is a first in the US and the designers and contractors are learning as they go and the state is paying the price for the experiment.

The artistic, curved structures are more common in Europe and Asia because of looser building codes, construction practices, and willingness to try newer materials like carbon fiber. Not to mention they are a b*tch to design.  Ohio is doing a study on carbon fiber prestressing strands vs steel strands, unfortunately the cost for carbon fiber is currently 4X that of steel.  State DOT's do not have room in their funding to increase costs by 4, so we tend to stick with what is known to work.

Thanks for the info. I should look on YouTube or the streaming services for a documentary, would totally watch it.

Apparently I was wrong (why is there no one correcting me, Brooklyn hipsters?), there are three in the NY area, or more probably? I neglected the new Kosciuszko Bridge, I've passed by it enough times, totally forgot.

I like using the Zakim Bridge in Boston as my background on various websites. Pretty cool looking at night when it's all lit up.

The Delaware Memorial Bridge is also a pretty cool one that I've driven over a bunch.

Progress on the New NY Bridge. Even under construction, with some of the cables now in place, looks dramatic.

I drive on the Goethals at least a couple of times a week, it's been pretty cool to see how the construction develops. Every once in a while you see a flatbed on Route 1 with one of the cable supports on it.

Kosciuszko is open. INFRASTRUCTURE. NY finally has a cable stayed bridge, took us long enough. We're behind the cutting edge in A LOT of things.

    • Beer selection good. Food bad. I've been twice here in Pittsburgh. I had fun both times, but don't expect an actual accurate golf competition. If you don't care about the accuracy part actually being judged, and just want to relax, good night out.
    • Correct. I was pretty good with the chip and run but I'm reconsidering. My course has three tier greens and you must, must, must get to the correct tier or you will have a very difficult putt.  So ... I made a list of 12 shots that I can play from 30 yards and in depending on the lie and the pin location.  Here's how I dug my hole. I spent Sunday calculating my carry to run distances for all my chips. After I was done, I researched it and compared it to typical charts and as I did, one of the articles mentioned that with the slopes on today's greens, that "chip and run" is not a shot that is used much anymore. Instead, most players use a single club (52 or 56) for all the shots around the green and vary the trajectory and the swing length to flop the distance.  This was an "a-ha!" moment for me as I remember a tour player on Mark Immelman's podcast who said the same thing ... and that got me thinking.  So here is what I practice ... < 10 yards: Chip Putt (a la Paul Runyan) 10 - 20 yards: Basic pitch, trap pitch, trail edge pitch (all the same shot, only thing that changes is the trajectory), downhill version/uphill version, flop shot (as in over a bunker) 20 - 40 yards: 1/2 wedge (sw) from fairway, and from rough 40 - 60 yards: 3/4 wedge (SW) 40 - 100 yards: low spinner Short sand (less than 30 feet), long sand  Does this make sense? Or am I overdoing it? I feel like if I'm inside 30, I can score. In 25 rounds this year, my putting average is <2 from nGIR so I feel like even if I miss the green, I can still score and my confidence has soared as a result. I welcome thoughts. 
    • Luau Pork: Rub Black Hawaiian lava salt to generously cover the pork butt. Lay strips of bacon across the top to cover the pork. 2 Tbsp liquid smoke 1 tblsp olive oil 1/2 cup of water or beef stock. Cook 15min/lb. ———————- The black salt gives the appearance of the pork being cooked underground as it usually is in a deep cooking pit. The liquid smoke gives that rich ‘slow cooked Smokey’ flavor. Amazingly good!
    • My understanding is that an "Old school" chip is using an 8, 7 or 6 iron and letting that sucker run.
