This structural form allows for the creation of wide spans, making arch bridges ideal for spanning large bodies of water or deep gorges. Here are some of the main types of arch bridges commonly used in civil engineering:

1. Round Arch Bridge
Also known as a semi-circular arch bridge, this is the most basic form of an arch bridge, with a simple circular shape. It is supported by two abutments and features a single arch that curves upward. This type of bridge was widely used during the Roman Empire and can still be found today in various ancient and modern designs.

2. Segmental Arch Bridge
As the name suggests, this type of arch bridge is made up of multiple segments instead of a single full arch. The segments are typically made of reinforced concrete and are joined together to create a curved shape. This design allows for longer spans and better resistance to tension and compression forces.

3. Multi-Arch Bridge
A multi-arch bridge consists of several arches placed in a row, often with decreasing heights towards the middle. This form is often used to bridge wider water bodies and provides more flexibility for the design of the bridge deck. It also allows for a more aesthetically pleasing look, with a rhythmic repetition of arches.

4. Horseshoe Arch Bridge
This type of bridge is characterized by its distinctive shape, resembling a horseshoe. It features a semi-circular arch with short, vertical sides that connect to the abutments. Horseshoe arch bridges were commonly used during the Islamic Golden Age and can still be found in various parts of the Middle East and North Africa.

5. Deck Arch Bridge
With a deck arch bridge, the deck is carried on top of the arches instead of hanging from them. This design allows for a longer span and can be used to create a wider and more open bridge deck. However, it requires stronger abutments to withstand the weight of the deck.
