HISTORIC STEEL TRUSS BRIDGES (89)

   During my traveling, photographing covered bridges, lighthouses, and historic homes, I come across these fascinating, architectural wonders. These steel truss bridges were the transitioning era from the covered bridges to the modern bridges of today. A lot of these trusses designs are similar to the wooden trusses of the covered bridges. Sadly, these bridges, just as the covered bridges, are getting more and more uncommon to see. As more efficient bridges are being made, these old steel truss bridges are being replaced. Some smaller roads and rural areas are still home to these bridges, but even these are quickly being replaced due to the practicability of the cost of restoration and the load limits. There are city, state, and federal governments that have purposely kept some of these old bridges for historical purposes. However, to fully maintain their their true historic perspective is during the rehabilitation process, the original rivets are to be replaced by the rivet process, not by the newer engineering with bolts and nuts. The vast majority of these bridges are over 100 years old, however there are a few that are 80 years old but still constructed in the historic process. I am just starting this blog on May 12, 2023, I hope you will enjoy the posts. Please note, to see all posts, at the right bottom of each page click on "older posts".
