Status (June 2019): I finally managed to make another post. I plan to make more but don't know how often I will be able to. I am also posting on my personal webpage and you can find information about me on my professional webpage.
There are many web pages to dedicated to cataloging all sorts of large, innovative, picturesque, or otherwise unique bridges. However, is is not so common to find pages dedicated to defective, deficient, ill-conceived, poorly maintained, or otherwise terrifying bridges - at least not unless they fail in a spectacular fashion. The most common results for a scary bridge search are for an article done as part of a much larger site. Also, some of those bridges are perfectly safe, fully functional, and often examples of exemplary engineering, construction, and maintenance. They are, at worst, worthy of an honorable mention on this site.
The entry of a bridge in this page is not intended as a sign of disrespect to its creators. No reason was found to believe that the bridge across Salto Del Soldado is unsafe, so long as use remains within its design criteria. But its overall nature makes it scary enough for an entry here; taking a walk across it could well get you killed. And the Conchi Viaduct is a remarkable feat of engineering and construction no matter how poorly maintained it is today.
Please remember that some bridges posted here were made with very limited resources, and are sometimes very old. Some were built in using horses, steam engines, or maybe just human labor. The fact that they still stand today speaks well of their creators. In some cases they were very short on resources: no professional engineers, very limited money, mostly (or all) salvaged material, and no heavy equipment. Nonetheless, they solved the problem with the resources they had. While the result can be rather scary, the author probably could not have done better given the constraints.
This is the discretion of the author. Considerations include:
With a few exceptions, all of the photos on this page were taken by the author (this site was not created to aggregate others work). One exception is the Treefort Bridge, of which the author built, and a photograph in which he appears. Another is a historic photograph. The current plan is for other photos to be used only rarely, as the situation (and copyright) warrant.
There is also an honorable mention section, for bridges that could be considered scary but don't meet the very low standards necessary for a full listing:
An Honorable Mention, Tahoma Creek Suspension Bridge.
It started with a discussion of the old Otowi Suspension Bridge in New Mexico. One engineer was discussing how few suspension bridges there are in New Mexico. The author pointed out one missing from the list, located on the Rio Grand south of Taos. Pictures of the bridge in question were later provided (see above). The bridge does indeed exist, though many engineers would consider it to be in need of a little maintenance, if not outright structurally deficient. Since that time, the author has continued locating and photographing scary bridges.
