Facts about Bridges - Information about Bridges and Tunnels

Forth Rail Bridge

Bridges are fascinating marvels of engendering that have managed to infuse themselves in our history like no other architectural objects. If you ever wanted to know more about bridges, their types, largest bridge structures or tragic failures, here is the perfect place to do so.

Bridge Types

Over the last 3000 years, engineers and architects have devised many ways of building bridges. Here you can see for yourself bridge types that are in use today, from what materials they are made, and for what uses are they built.

Arch Bridges

Arch Bridge is one of the most popular types of bridges, which can today be found all across the world. Here you can follow their path through history, from their first inception some 3000 years ago in Greece, to their renaissance in Ancient Rome, all up to modern times.

Bridge Failures

Bridges are structures that need to be built to withstand incredible external forces and last for decades or centuries. Sadly many bridges have succumbed to their wounds and took with them many human lives. Here you can find some of the most famous bridge disasters in human history.

Suspension Bridges

Suspension bridge is a very old type of bridge. It allows spanning of obstacles like rivers and chasms that other, more conventional, bridge types don't. But it didn't appear in the shape that we know today until more modern materials didn't appear.

Types of Suspension Bridges

Suspension bridges are relatively modern invention (at least those that are built to be large). They are cheaper and can have longer spans but can’t sustain as much weight as other types of bridges. Here are some variants of suspension bridges.

Cable-stayed Bridges

Cable-stayed bridge is a variant of a suspended bridge that is more economic that other types of bridges on middle distances and for middle loads. It also allows for some rather interesting designs.

Truss Bridge

One of the first modern bridges to be made were truss bridges. They could be made of wood which some places had plethora and could withstand larger weights. They were later made of iron and steel. Many of those old modern bridges still stand.

Cantilever Bridges

Modern cantilever bridge is one of the safest bridge variants because it can carry largest load. Since the dawn of the modern bridge, in 19th century, they were used to carry railroads.

Tied-arch Bridges

Tied-arch bridge is a bridge that carries itself and can be constructed at places that have problems with unstable soil. It can be problematic if it is not maintained properly but there are tied-arch bridges that are over a century old and are still in use.

Beam Bridges

Beam bridge is the oldest and the simplest type of the bridge. It appeared when the first tree fell over the stream and a human crossed it. Today we still make bridges that use similar principle.


Footbridge is a bridge for pedestrians. It is often simple (although it doesn't have to be) and its purpose is to take pedestrians over some obstacle like a river, road traffic or a railroad.

Movable Bridgee

First moveable bridges were built to prevent the enemy to reach the gates of the castle. Today they are made at places where a cheap bridge is needed but there is also a need for an unobstructed river traffic. Read more about different types of movable bridges.

Channel Tunnel

One of the seven modern wonders of the world – Channel tunnel between Britain and France has a much longer history than we could assume at first sight. It existed in the minds of dreamers for two centuries.
