A deck arch bridge is a type of bridge that has been used for centuries, but its popularity has declined in recent times due to various reasons. Despite this, it remains one of the oldest and most iconic types of bridges, known for its strength and durability.

One of the primary concerns with deck arch bridges is the restriction they impose on the width of the river or waterway beneath them. This can lead to increased flow rates, which in turn can cause erosion around the bridge's foundations. Additionally, constructing multiple arches can be a complex process, requiring temporary supports in waterways and careful planning for approach roads.

The shape of the arch has also evolved over time, from semi-circular to elliptical with a low rise-span ratio. The use of random masonry (uncut and unprepared stones) or cut stone allows for different approaches to construction. For example, when using masonry, the angles of the faces can be cut to minimize shear forces.

Deck arch bridges typically employ a quantity of fill material above the arch to increase its dead weight and prevent tension from occurring as loads move across the bridge. The more weight placed on the bridge, the stronger it becomes. In fact, the earliest compression arch bridges relied on a keystone in the middle of the bridge to bear the weight of the rest of the structure.

Construction of a masonry arch bridge involves building each arch over a temporary timber frame, known as a centring. As a result, these bridges are designed to be constantly under compression, taking advantage of the strength of materials like stone and brick in this direction.

The earliest recorded examples of deck arch bridges date back to 1300 BC, with the Mycenaean Arkadiko bridge in Greece being an early example. The Indian proverb 'the arch never sleeps' highlights the recognition of the arch's strength as a resistant structure. Its development was initially pioneered in Mesopotamia and then spread globally.

In conclusion, deck arch bridges have been a cornerstone of bridge construction for centuries, offering a unique combination of strength, durability, and aesthetic appeal. While they may not be as widely used today, their legacy continues to inspire engineers and architects around the world.
