I joke to my wife that this is "my" bridge, which of course it's not, but I have a small part in a research/engineering project that will make it into what's being called "smart infrastructure": capable of sensing, and telling not just engineers but the public at large, how it feels. I'll post more about that as our project unfolds, over the next few years.


My very cool bridge connects New Hampshire with Maine, across the strong tidal flows of the Piscataqua River.

Above, I posted some photos of the Memorial Bridge in Portsmouth, NH, where I have a small role in a new "smart infrastructure" engineering project. Some IT students working with one of the investigators recently put together this rotate-able 3D model, looks cool to me:

Is it possible that it is designed to get a protective oxide coating, so that the visible rust is only cosmetic?

Or is it just done for artistic reasons and will degrade much faster than necessary?

Or are they just being cheap?

If a bare steel bridge is built in an a relatively arid environment free from corrosive atmosphere (salt water) and of sufficiently thick steel, I'd expect it to easily last over 100 years sans paint.

If it's right over a creek like that in a river bottom,
I would not call it "relatively arid."
It will get condensation quite often.

Dingus,

That's Cor Ten steel. http://www.centralsteelservice.com/cor-ten.htm


It's also a favorite of artists who want the "aged" look.

Hey you all, & Dingus, the bridge crews around here( Tri state NY,NJ,CT) have been cool so far but they have pointed out that they have cameras too.

As for the over built foot bridge, that is Art, and How to spend A Million $$
If the increase in quality writing continues I will not dare share a TR to the "Park"
Where good tax dollars have been spent.

It is a whoot and may well fit on this thread?"?

With some paint and repaint, a thousand? Paint is way cheaper than new steel.

I just don't get it...

We people are fickle creatures, and I think you'd be hard pressed to find a public works project that was designed to last 100 years, let alone a 1000. Not only is it tough to get a community to approve funding for public works, it's tougher still for them to keep funding maintenance on those projects. That's the sad reality of it.

Also looking at that unpainted bridge, I'd guess the area you'd have to be most concerned with failing over time is the base connection.


You can paint it as often as you want, but it is a dynamic structure and you're not going to be able to keep paint in that joint and hence the areas in most need of protection likely won't be able to be protected.

With all that said, streams and rivers are also dynamic systems. I'd venture to say in 1000 years one shouldn't be surprised if the water way changed course or one or both of the banks eroded away to the point that a new bridge would be needed no matter how much care was used in the design, construction and maintenance of the original structure.
