The Verrazano-Narrows Bridge, completed in 1964, connects Brooklyn to Staten Island and was the first bridge to do so. It is a double deck suspension bridge and was once the longest in the world. Its installation led to the rapid development of Staten Island, which was previously isolated and only accessible by ferry. The bridge […]
The Tay Bridge disaster in Dundee, Scotland, occurred on December 28, 1879, when a passenger train collapsed into the River Tay, killing all 75 passengers. The bridge was inadequately designed for the weather conditions and theories about bridge fatigue and design have been advanced. The disaster resulted in the death of Sir Thomas Bouch’s son-in-law […]
An access point bridge connects two isolated computer networks using a device called an “access point” in bridge mode. It extends the range of a wireless signal and is effective for connecting two existing networks wirelessly. Some access points can form only one wireless bridge, while others can connect to several additional access points simultaneously. […]
Becoming a bridge inspector requires an engineering degree, years of experience as an assistant technician, computer and scuba diving courses, and strong organizational skills. Attention to detail is crucial, as incorrect inspections can have serious consequences. Travel and working in adverse weather conditions are also expected. The job of a bridge inspector carries a great […]
A routing bridge connects multiple networks and allows communication between them, but does not handle network layer functions like IP assignment. It can be used to connect wired and wireless networks. It should not be confused with a bridge router, which combines the functions of a bridge and a router. A routing bridge is a […]
Kew Bridge Steam Museum in London explores steam engines for water pumping and supply. The museum features a variety of steam and beam engines and other technologies. It was once a fully functioning pumping station and was converted into a museum in 1973. The heart of the museum is Steam Hall, which features a green […]
Bridge design software simplifies the complicated process of designing a bridge by performing engineering calculations, identifying weaknesses, and creating simulations to test the boundaries of a design. It also allows for detailed planning and the production of 3D models. Bridge design software is a software product used in bridge design. Before the development of such […]
Bridge piers support the bridge and can be made of concrete, stone, or metal. They can be submerged in water and allow for roads to be built underneath. The pier shape is determined by the specific application and other factors such as wind. A bridge pier is a type of structure used to support a […]
The Tacoma Narrows Bridge in Washington state collapsed in 1940 due to a combination of design flaws, aerodynamics, and self-excitation. The collapse revolutionized bridge-building, and a new, safer bridge was built in 1950. On November 7, 1940, the big news of the day was the total failure and collapse of the Tacoma Narrows Bridge in […]
Toothpick bridges are a hands-on way to teach students about engineering, architecture, and construction. Participants build bridges using only toothpicks and glue, with rules specifying the number of toothpicks, type of glue, and other requirements. Competitions reward the most supported weight, unusual design, lightest bridge, or longest span. Triangles are a unique shape that distributes […]
Jet bridges, also known as airbridges or cargo bridges, allow passengers to board and disembark directly through an airport terminal without stairs. They are becoming standard at airports worldwide and can accommodate passengers in wheelchairs or with strollers. Jet bridges consist of a long arm that attaches to the gate in the airline terminal and […]
A moon bridge is a decorative pedestrian structure that is often placed over water, with a semi-circle shape that reflects the water in a full circle. It originated in Japan and is suitable for narrow waterways. There are two basic types of moon bridges, and they are popular in Asian garden styles. A moon bridge, […]
Suspension bridges suspend the roadway from cables attached to a main cable that runs over the length of the bridge. They are strong, light, and beautiful. The basic design has been around for centuries, and engineers continue to push the limits of the spans suspension bridges can span. A suspension bridge begins with the construction […]
A bridge router combines the functions of a bridge and a router to connect two LANs. Bridges connect LAN segments, while routers direct traffic. A bridge router is less expensive than using both a bridge and a router and provides just as good service. Most home networks use a peer-to-peer networking system and do not […]
A girder bridge is a simple and inexpensive type of bridge made of a horizontal beam supported by posts or pillars. It works on the principles of compression and tension and is commonly made of reinforced concrete or steel beams. The biggest limitation is its length, but longer spans can be achieved by daisy chaining […]
Truss bridges are old and durable, made up of pillars, ropes, and diagonal webs forming triangles. They support themselves using tension and compression. Different types include the king post, queen post, and Howe truss, with longer spans possible in modern variations. Examples include the New Fork River Bridge, Bridge over the River Kwai, Navajo Bridge, […]
Highway bridges are structures designed for vehicles to safely cross over or under obstacles. They are designed by engineers and can be made of various materials and systems. Maintenance is necessary to ensure public safety and prevent costly replacements. Interchanges and tunnels are common types of highway bridges. A highway bridge is a major road […]
A through bridge has the road bed suspended below the trusses or arches, with the roadway passing through them. Truss, suspension, and arch bridges are common types. Through bridges can be further classified by design, such as through truss or through arch. The roadway on an arch bridge is usually suspended from the arches by […]
Folding bridges are movable bridges that fold to allow vessel traffic to pass. They can be used for pedestrians or vehicles and are often made of metal with hydraulic systems controlling movement. Some designs curl into a circular shape. Folding bridges can be portable and useful for military or temporary bridge repair. They stand out […]
Pipe bridges are built to allow pipelines to cross rivers, ravines, and unstable areas. They can transport water, effluents, and liquefied natural gas. Engineers consider weight, weather, and environmental impact when designing these bridges. Some are built on site, while others are assembled nearby and lifted into place. In northern countries, mechanical pipe bridge crossings […]
