Cor-Ten still lives on.
If fabricated with its limitations in mind it works. But it has quite a record of failure, including Atlanta's Omni.
In all seriousness, it is going to be interesting to see what happens with respect to the condition of the steel on these bridges over the next few decades. Many of these bridges are composed of the so-called weathering steel. This weathering steel is intended to develop a patina of rust and then quit rusting. If I recall correctly, I believe that the infamous Omni Coliseum in Atlanta, Georgia was built from a similar material but it could not stand up to the humid Georgia climate.
Eastern Kansas does not have Gulf Coast humidity but it's not exactly a dry climate either. This bridge is going to have to sit out in the rather humid environment of Eastern Kansas. In forty or fifty years we can see how well it will have performed.
We can see how some of the Victorian era wrought iron bridges have performed across Kansas and the rest of the country. There are some 1870s and 1880s bridges out there that are not doing so bad as far as the condition of the iron is concerned. On the other hand there are much newer bridges in the region which are deteriorating rapidly due to moisture and salt. This bridge will have a chance to prove itself... how will it fare?
Not a Bowstring Nick... Just a "Welded Wannabe"! (Somewhere in the unknown region between a Pratt and a Parker.
I've said it a million times... I can handle these MOB's when they are used in new construction or replacing non-historic spans. But when an historic truss is sacrificed and the public is led to believe that it is a good thing... It's not! Even the rust on them comes off as fake to me as it tries to imply that they are "historic looking". I think they would actually look better with a bright coat of paint on them, but I know the manufacturers tout them as no paint needed. I won't be around for it but I'll be surprised if they last 50 years.
My Rant for the evening.
Up until about 40 years ago, Douglas County had a nice collection of early 20th century trusses. Now they are no more.
If you are a resident of Douglas County and you want to see some nice truss bridges, may I suggest Miami County...
Had not previously noticed that old listing for whatever reason....wreason....wow that old thru truss a beauty!! sad sad sad
Here is the former bridge:
It was the last remaining historic truss bridge in Douglas County save for the railroad bridge at Eudora. With the demolition of the old bridge, Douglas County became the first county in the eastern third of Kansas (roughly), without a single vehicular metal truss or Marsh arch within its boundaries. I would not be surprised if one or two other Counties have joined Douglas County since then.
Fun modern bridge I found on satellite this week, a hearty bridge with nice wood planking over Washington Creek just east of the town of Lone Star, Kansas.
