Lots of bridges are made primarily from timber. These timber bridges have a lot of inherent benefits that relate to the material itself.
The Bridges That Are Constructed Out of Steel Have Vulnerabilities that Won't Affect Those Made of Wood
Bridges are usually made out of concrete, wood, or steel. While steel often seems like a very powerful material, it has vulnerabilities that will not affect wood. Steel has a strong tendency to rust, which is certainly not a concern with many bridge-building materials.
Rust can be particularly hazardous on bridges because it can truly threaten the structural stability of the entire bridge. Stopping a bridge or other structure from rusting further when it has already started to do so can also be challenging. While concrete will not experience the same issues as steel, it will also potentially present concerns that builders will not encounter with timber.
Concrete Bridges Can Start to Crumble in Time and Wooden Bridges Will Not Exhibit Comparable Issues
People can use concrete very successfully in a number of construction projects, and there are concrete bridges that have endured for a while. However, concrete material is still prone to crumbling, especially if it has to absorb a lot of stress from driving cars, footsteps, and everything else that a bridge will experience over the course of its existence.
These problems are less pronounced when concrete is used to make other sorts of surfaces that people use for walking since the concrete will be supported by something underneath. When concrete is used in walls, it's also subjected to more consistent levels of pressure. Situations become less predictable when the concrete is used to make a bridge. Concrete is also not always as resilient as wood when it does start to break down, especially when it's compared with modern, treated forms of wood.
Modern Bridge Construction Experts Will Make Use of Special Preservatives That Will Help to Make a Wooden Bridge More Consistently Stable
The people who are concerned about how different environmental variables could affect a timber type of bridge should remember that bridge builders are able to use advanced techniques now that will help them preserve these bridges. Those preservatives will help to keep the wood fresh and powerful for an extended period of time, while also making the wood resistant to everything from insects to problems with both water and fire. These sorts of treatments can even help to make wooden bridges more successful in multiple climates.
