Counting the total number of bridges in the world may be difficult at best and impossible at worst. Before we even begin to find an answer, we need to answer some critical questions:

  • What qualifies as a bridge?
  • Does any structure built to span a physical obstacle count as a bridge?
  • Should we count a wood plank connecting two sides of a three-foot-wide creek?
  • Are we referring to bridges that are wide enough to support car traffic?
  • What about pedestrian bridges?

The sheer number of bridges around the world and the constantly fluctuating number of them make this a complicated question. To get an exact number of bridges, we would need to take a snapshot of the surface of the earth. Of course, taking the snapshot is the easy part. Counting the bridges would be a monumental undertaking. And by the time we had an exact count, the number would be incorrect. There would be new bridges built, and old ones disappeared.

How many kinds of bridges are there all over the world?

For thousands of years, bridges served humanity. From the earliest civilizations to the present, bridges have served an important role. There are many different types of bridges in the world.

Arch Bridges

Humans all over the world have been building arch bridges for millennia. The ancient Greeks and Romans were expert arch bridge builders. The arch bridge is the most architecturally distinctive type of bridge. The arch is the feature that makes this type of bridge strong. Its most distinctive structural component, the arch, is always located below the bridge. Arch bridges can be constructed with a minimum of one arch, but they can be built with multiple arches.

What is the longest arch bridge in the world?

Chaotianmen Bridge, located in China, is the longest steel arch bridge in the world.

Tied Arch Bridges

Tied arch bridges, often called bowstring bridges or bowstring arches, look similar to arch bridges. This type of bridge transfers the weight of the load to the top chord that is connected to the bottom cords in the foundation. Tied arch bridges are some of the most beautiful. Unfortunately, they are expensive to repair and maintain.

Cantilever Bridges

Although cantilever bridges look similar to arch bridges, they are built with different technology.  Cantilever bridges support their load through diagonal bracing with horizontal beams supported only on one end.

Truss Bridges

Truss bridges are also popular. They are usually built with a diagonal mesh. Due to its design, a truss bridge can endure heavy loads and stronger forces than other types of bridges.

Beam Bridges

It is the simplest type of bridge. Each bean bridge contains one or multiple horizontal beams. Beam bridges are some of the oldest bridges constructed by humans. In the past, humans dropped logs over creeks, ditches, and narrow rivers. Modern beam bridges are separated into plate girder bridges, box girder bridges, girder bridges, simple beam bridges, and box girder bridges. There are fixed and movable truss bridges. Some of the standard build materials are steel, timber, iron, prestressed concrete, and steel-reinforced concrete.

Suspension Bridges

Spreading ropes and cables are dominating features of suspension bridges. Today, suspension bridges are very popular around the world. In ancient times, vines or ropes were used to construct this type of bridge. They are very flexible and respond well to vibrations caused by wind or earthquake. The Golden Gate Bridge, in San Francisco, California, is one of the most famous suspension bridges in the world.

Cable-Stayed Bridges

Cable-stayed bridges use deck cables that are connected to pylons. Even though cable-stayed bridges use cable, it is a very different type of construction. This type of bridge is ideal for medium and long distances. The most common build materials used on cable-stayed bridges are post-tensioned concrete, concrete or steel pylons, steel rope, and box girders. Although the Brooklyn Bridge is technically a suspension bridge, it also has components of the cable-stayed design.

Fixed Bridges

Most bridges are fixed bridges. That means that there are no movable parts in fixed bridges. They are engineered to stay in place until they are demolished.

Movable Bridges

Movable bridges are hybrid structures. They contain fixed and temporary features. Movable bridges offer the modularity and flexibility of temporary bridges. Movable bridges are designed to move-out-of-the-way as needed, to allow ships or any other type of under deck traffic through. London Bridge is the most famous movable bridge in the world.

Temporary Bridges

Temporary bridges are made of modular elements that can be moved with minimal construction. This type of bridge is popular with military operations. Temporary bridges are not intended as permanent structures.

Viaduct

A viaduct is a bridge or a connected series of bridges. Viaducts are ideal for connecting two points together that are of the same height. They are built over valleys, water, canyons, and gorges.

All viaducts are bridges, but not all bridges are viaducts.

Viaducts are popular in railroad centers such as Chicago, London, and Atlanta.

What is the longest bridge in the world?
