Continuous Truss Bridge
A continuous truss bridge is a truss bridge that extends without hinges or joints across three or more supports. A continuous truss bridge may use less material than a series of simple trusses because a continuous truss distributes live loads across all the spans; in a series of simple trusses, each truss must be capable of supporting the entire load. Although some continuous truss bridges resemble cantilever bridges and may be constructed using cantilever techniques, there are essential differences between the two forms. Cantilever bridges need not connect rigidly mid-span, as the cantilever arms are self-supporting. Although some cantilever bridges appear continuous due to decorative trusswork at the joints, these bridges will remain standing if the connections between the cantilevers are broken or the suspended span (if any) is removed. Conversely, continuous truss bridges rely on rigid truss connections throughout the structure for stability. Severing a continuous truss mid ...

USACE Astoria-Megler Bridge
The United States Army Corps of Engineers (USACE) is the military engineering branch of the United States Army. A direct reporting unit (DRU), it has three primary mission areas: #The Engineer Regiment, Engineer Regiment, military construction, and civil works. USACE has 37,000 civilian and military personnel, making it one of the world's largest public services, public engineering, design, and construction management agencies. The USACE workforce is approximately 97% civilian, 3% active duty military. The civilian workforce is mainly located in the United States, Europe and in select Middle East office locations. Civilians do not function as active duty military and are not required to be in active war and combat zones; however, volunteer (with pay) opportunities do exist for civilians to do so. The day-to-day activities of the three mission areas are administered by a Lieutenant general (United States), lieutenant general known as the List of United States Army Corp ...

Governor Harry W
A governor is an administrative leader and head of a polity or political region, in some cases, such as governors-general, as the head of a state's official representative. Depending on the type of political region or polity, a ''governor'' may be either appointed or elected, and the governor's powers can vary significantly, depending on the public laws in place locally. The adjective pertaining to a governor is gubernatorial, from the Latin root ''gubernare''. In a federated state, the governor may serve as head of state and head of government for their regional polity, while still operating under the laws of the federation, which has its own head of state for the entire federation. Ancient empires Pre-Roman empires Though the legal and administrative framework of provinces, each administered by a governor, was created by the Romans, the term ''governor'' has been a convenient term for historians to describe similar systems in antiquity. Indeed, many regions of the pre-Roman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Charles M
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (James (wikt:Appendix:Proto-Indo-European/ǵerh₂-">ĝer-, where the ĝ is a palatal consonant, meaning "to rub; to be old; grain."

Julien Dubuque Bridge
The Julien Dubuque Bridge is a bridge over the Mississippi River that connects Dubuque, Iowa and East Dubuque, Illinois. The bridge is part of U.S. Route 20 (US 20). It is one of two automobile bridges over the Mississippi in the area (the Dubuque–Wisconsin Bridge north links Dubuque with Wisconsin), and is listed in the National Register of Historic Places. Description The Julien Dubuque Bridge is a light grey color. The bridge spans and is 28 feet wide. The longest span is 845 feet. History For a number of years, people living in the area wanted a bridge to replace the old bridge, which was called either the "High Bridge" or the "Wagon Bridge." However, economic conditions at the time made it difficult to get the financing together to build a new bridge. During World War II, a new bridge became even more important as it would help facilitate military transportation. In 1942, the first parts of the bridge began construction. In 1943, the bridge was completed. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Bridge Strike
Bridge strike or tunnel strike (also known as bridge bashing) is a type of transport accident in which a vehicle collides with a bridge, overpass, or tunnel structure. Bridge-strike road accidents, in which an over-height vehicle collides with the underside of the structure, occur frequently and are a major issue worldwide. In waterways, the term encompasses water vessel–bridge ship collision, collisions, including bridge span and support structure collisions. Impacts In United Kingdom, railway bridge strikes (called "bridge bashing") happen on an average of once every four and a half hours, with total of 1789 times in 2019. Several bridges have been hit over 20 times in a single year. The total cost borne by the state was around £23 million. In Beijing, China, 20% of all bridge damages are caused by bridge strikes. Texas Department of Transportation estimated in 2013 that an average cost to repair a bridge strike is $180,000 USD. Even without damages to the bridges, the strike ...

Francis Scott Key Bridge (Baltimore)
The Francis Scott Key Bridge (informally, Key Bridge or Beltway Bridge) was a steel arch continuous through truss bridge that spanned the lower Patapsco River and outer Baltimore Harbor/Port. Opened on March 23, 1977, it carried the Baltimore Beltway ( Interstate 695 or I-695) between Dundalk and Hawkins Point. It collapsed on March 26, 2024, after a container ship struck one of its piers. Officials have announced plans to replace the bridge by fall 2028. Initially named the Outer Harbor Crossing, the bridge was renamed in 1976 for poet Francis Scott Key, who wrote the lyrics to "The Star-Spangled Banner", the U.S. national anthem. At , it was the second-longest bridge in the Baltimore metropolitan area, after the Chesapeake Bay Bridge. Its main span of was the third-longest of any continuous truss in the world.Durkee, JacksonWorld's Longest Bridge Spans, National Steel Bridge Alliance, May 24, 1999.

The Ikitsuki Bridge is a continuous truss bridge that connects Ikitsuki to Hirado Island. Completed in 1991, it has a main span of . It is the longest continuous truss bridge in the world. History The bridge allows automobile access from Ikitsuki to Hirado and the rest of Japan. In 2009, a crack which seriously damaged the safety of the bridge was found in a diagonal member near an intermediate pier during an inspection for determining points to be annually inspected. The crack grew to be 20 cm long, and was thought to be caused by wind-induced vibrations.
