The masonry arch bridges of stone or brick are the most genuine of arch bridges, some lasting a thousand years. Because they are made of worked stone, there is a slight chance they might even stand without mortar, like the Pont du Gard aqueduct. Yet arch bridges using rough hewn stones like Changhong Bridge need mortar to stand. Arches with a core of reinforced concrete covered by facade stone for decoration are not to be included in this list, the load-bearing part of the arch should be cut stone or brick, or as follows, unreinforced concrete.
In a closed spandrel stone arch bridge the hollow space can be filled with rubble and loose material. It can also be filled with concrete, in which case the filling itself become able to bear load in addition to the load carried by the ring of voussoirs. If the voussoir stones are thin they can not take a lot of weight so instead it is the concrete filling that becomes the structural part of the arch. The next step is to remove the voussoir stones completely, or only use them as facade stones. An unreinforced concrete arch is technically a masonry arch that use only very small stones, that is the aggregate of the concrete, sand and gravel. Such an arch would not stand without mortar.
Some modern bridges are built masonry style with precast concrete blocks, like Gladesville Bridge that has a span of 305 metres (1000 ft). These types are not in this list because their blocks are most likely made of reinforced concrete, that may make the assembled arch to have more in common with a modern reinforced concrete arch than a stone masonry arch.
The Maidenhead Railway Bridge may have the two longest arches made of bricks, 39 metres (128 ft).
Building new masonry arch bridges today is a solely Chinese business. There are 18 stone arch bridges with spans exceeding 100 m (330 ft). [1] There are probably several dozens of stone arches exceeding 40m in the Fujian province only. [2] Almost all bridges were built after 1950.
This list contains the longest masonry arch spans ever built being at least 50 metres (164 ft).
Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound and pasted together by mortar. The term masonry can also refer to the building units themselves.
An arch is a curved vertical structure spanning an open space underneath it. Arch can either support the load above it or perform a purely decorative role. The arch dates back to fourth millennium BC, but became popular only after its adoption by the Romans in the 4th century BC.
Stonemasonry or stonecraft is the creation of buildings, structures, and sculpture using stone as the primary material. Stonemasonry is the craft of shaping and arranging stones, often together with mortar and even the ancient lime mortar, to wall or cover formed structures.
The ancient Romans were the first civilization to build large, permanent bridges. Early Roman bridges used techniques introduced by Etruscan immigrants, but the Romans improved those skills, developing and enhancing methods such as arches and keystones. There were three major types of Roman bridge: wooden, pontoon, and stone. Early Roman bridges were wooden, but by the 2nd century stone was being used. Stone bridges used the arch as their basic structure, and most used concrete, the first use of this material in bridge-building.
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct may be made from a series of arches, although other more economical structures are typically used today.
Eugène Freyssinet was a French structural and civil engineer. He was the major pioneer of prestressed concrete.
A through arch bridge, also known as a through-type arch bridge, is a bridge that is made from materials such as steel or reinforced concrete, in which the base of an arch structure is below the deck but the top rises above it. It can either be lower bearing or mid-bearing. Thus, the deck is within the arch, and cables or beams that are in tension suspend the central part of the deck from the arch.
The Solkan Bridge is a 219.7-meter (721 ft) arch bridge over the Soča River near Nova Gorica in western Slovenia. With an arch span of 85 meters (279 ft), it is the world's longest stone arch railroad bridge. It holds this record because later construction technology used reinforced concrete to build bridges. It was originally built to carry the Bohinj Railway in the time of the Vienna Secession, between 1900 and 1905, and officially opened in 1906.
A skew arch is a method of construction that enables an arch bridge to span an obstacle at some angle other than a right angle. This results in the faces of the arch not being perpendicular to its abutments and its plan view being a parallelogram, rather than the rectangle that is the plan view of a regular, or "square" arch.
The Bridge near Limyra is a late Roman bridge in Lycia, in modern south-west Turkey, and one of the oldest segmented arch bridges in the world. Located near the ancient city of Limyra, it is the largest civil engineering structure of antiquity in the region, spanning the Alakır Çayı river over a length of 360 m (1,181.1 ft) on 26 segmental arches. These arches, with a span-to-rise ratio of 5.3:1, give the bridge an unusually flat profile, and were unsurpassed as an architectural achievement until the late Middle Ages. Today, the structure is largely buried by river sediments and surrounded by greenhouses. Despite its unique features, the bridge remains relatively unknown, and only in the 1970s did researchers from the Istanbul branch of the German Archaeological Institute carry out field examinations on the site.
The Langwieser Viaduct is a single track reinforced concrete railway bridge spanning the Plessur River and the Sapünerbach, near Langwies, in the Canton of Graubünden, Switzerland.
Canal Lake Concrete Arch Bridge is an arch bridge in Ontario, Canada, spanning a portion of Canal Lake on the Trent–Severn Waterway between Balsam Lake and Lake Simcoe. It is north-northeast from the town of Bolsover.
The Coxs River railway bridges are two heritage-listed railway bridges that carry the Main Western Line over the Coxs River at Wallerawang, City of Lithgow, New South Wales, Australia. The bridges were designed by engineering staff of the New South Wales Government Railways and built in 1870 by day labour. The property is owned by Transport Asset Holding Entity, an agency of the Government of New South Wales. It was added to the New South Wales State Heritage Register on 2 April 1999.
