Suspension Bridge
Bridge that has cables suspended between towers that hold up the deck. This type is good for long spans such as in the case of river crossings.
Beam Bridge
A horizontal structure supported at each end by piers. Mainly used for short to medium spans and is one of the simplest bridge types.
Arch Bridge
Bridge with abutments at each end shaped as a curved arch. Often used for overpasses and when there is a need to preserve the natural beauty of a landscape.
Bascule Bridge
Also known as a drawbridge, it features a movable deck that can be raised and lowered using counterweights. Ideal for river crossings with ship traffic.
Bailey Bridge
Another type of portable, pre-fabricated truss bridge, similar to the Acrow bridge, but specifically designed during World War II for military use and now also for civilian purposes.
Covered Bridge
Traditional wooden bridge with a roof and enclosed sides. Used primarily for pedestrian or light vehicular traffic, adding aesthetic and historical value to the location.
Movable Bridge
Features a deck that moves to allow boat traffic to pass. Types include bascule, lift, and swing bridges. Suitable for busy waterways requiring tall ship access.
Tied-arch Bridge
Arches are restrained at the ends by tension members. It doesn't exert horizontal thrust on the support structures, making it suitable for locations that cannot support large horizontal forces.
Stressed Ribbon Bridge
Features a slender deck with tight, straight cables directly supporting it, often for pedestrian use. The design provides an aesthetically pleasing low-profile structure.
Point-supported Bridge
Uses columns or piers to support the deck at discrete points. It is commonly employed in the construction of flyovers and urban overpasses.
Transporter Bridge
Features a suspended gondola or platform which transports vehicles and passengers across a river or canal. Suitable when there is a need to avoid interfering with traffic on the waterway.
Cantilever Bridge
Constructed using cantilevers, which are horizontal structures supported on only one end. Used in locations where a central support would be impractical.
Viaduct
Long bridge composed of multiple small spans. Great for crossing over valleys or other terrain where the construction of large piers is possible.
Integral Bridge
The substructure and superstructure are integrated without any joints. This type is good for durability and ease of maintenance, commonly used for small to medium spans.
Trestle Bridge
Supported by a network of towers or piers laid out in a repetitive pattern. This type is often employed for railroads over valleys, streams, and gorges.
Pedestrian Bridge
Designed exclusively for pedestrians and sometimes cyclists. Commonly used in urban areas to safely cross over busy roads or natural obstacles.
Extradosed Bridge
Combines elements of both cable-stayed and pre-stressed concrete girder bridges, with the towers not being as tall as those of cable-stayed bridges. Suitable for spans where a full cable-stayed bridge may not be necessary.
Continuous Span Bridge
Without intermediate supports within the spans, this bridge type uses materials flexibly and efficiently. Ideal for medium-span applications like highway overpasses.
Floating Bridge
Made of pontoons or barges that support the bridge deck. Best suited for short spans across water bodies where anchoring is possible.
Acrow Bridge
A portable, pre-fabricated truss bridge designed for temporary use, commonly in military and emergency scenarios to provide quick assembly over gaps.
Double-decker Bridge
Characterized by two levels, typically with vehicles on one level and trains or pedestrians on another. Useful in dense urban areas where space is limited.
Cable-stayed Bridge
Features one or more towers from which cables support the bridge deck. A balance between simplicity and aesthetics, suitable for medium to large spans.
Stress-Ribbon Bridge
Has a narrow deck and is supported by tensioned cables running directly alongside the deck. This type of bridge provides an aesthetic solution with minimal environmental impact.
Truss Bridge
Comprises a structural network of triangles that support the bridge. This design uses materials efficiently and is suitable for various applications including road and rail.
Living Root Bridge
Constructed from the aerial roots of living trees, mainly the rubber fig tree. These bridges are sustainable and integrate completely with the surrounding ecology.
Rainbow Bridge
Characterized by large arches forming a shape reminiscent of a rainbow. Often chosen for their strong visual impact and to serve as a landmark.
Timber Bridge
Built primarily with wood, they are among the oldest types of bridges and are valued for their environmental friendliness and aesthetic appeal.
3D Printed Bridge
Produced using three-dimensional printing technology, often from metal or concrete. Focused on innovative design, material efficiency, and reduction in labor.
Steel Girder Bridge
Utilizes steel beams that support the bridge's deck. This bridge type is commonplace on highways due to its strength and ease of construction..
Network Arch Bridge
A type of tied-arch bridge where the ties between the arches and the deck create a network pattern. It allows for a longer span with less material.
