You either go over, under or through but never around a bridge. They can be used to cross oceans and rivers, transport cars, and connect two cities. While bridges carry out various functions, it is their shape and size that make all the difference. Here’s a closer look at what we have worked on in the past and what makes each bridge unique:
1. Arch Bridge
The arch bridge is one of the most popular types of bridges, it came into use nearly 3,000 years ago, especially during the Roman Empire. The arch can always be found located at the bottom of the bridge. This type of bridge is supported mostly by forces of compression, carrying some tension under the arch. You can still see this style used today but with a modern twist. This is a Glulam free span arch bridge we made, perfect for a stroll out in a park.
2. Short-Span Bridge
In the case of Short-Span Bridges, the decking is supported by joist framing. The load carried by the decking and the joists are transferred to the pile caps, piling, and abutments.
3. Beam Bridge
A beam bridge is known for being the simplest and most cost-effective bridge to build. Beam bridges tend to be short since most of the support is located toward the edges. They can typically be found in beaches, lakes and national parks across the United States. Check out this steel free span bridge we built to protect the environment and get individuals safely to the other side.
4. Cantilever Bridges
Cantilever bridges are most similar to arch bridges in appearance yet use truss formation above and below the bridge. Their primary function is to be used for road traffic and long distances. Here’s a before shot of our cantilever bridge in Northville, Michigan.
As you can see, a bridges design depends greatly on its purpose. Whether it’s for functional, aesthetic or economic reasons, all these things are taken into consideration when building. Despite the different style or size, bridges are spectacular structures that make it easier for us to travel from place to place. There’s a lot more to these impressive landmarks than meets the eye, and our team at Nature Bridges is excited to help you get started on your next project.
