Florida International University Pedestrian Bridge Collapse
The Florida International University pedestrian bridge collapse occurred on March 15, 2018, when a 175-foot-long (53 m) section of the FIU-Sweetwater UniversityCity Pedestrian Bridge collapsed while under construction. The collapse resulted in six deaths (one worker and five motorists), ten injuries (six serious and four minor), and eight vehicles being crushed underneath. Of the serious injuries, one employee was permanently disabled. At the time of the collapse, six lanes of road beneath the bridge were open to traffic. The pedestrian bridge was designed to connect the town of Sweetwater to the campus of Florida International University (FIU) in University Park, a suburb west of Miami, Florida, United States. The two were separated by a busy eight-lane highway, which the bridge was designed to span. The engineering design error that directly led to the collapse was identified by the National Transportation Safety Board (NTSB) as a miscalculation of r ...

National Transportation Safety Board
The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, bridge failures, and railroad accidents. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. It has four regional offices, located in Anchorage, Alaska; Denver, Colorado; Ashburn, Virginia; and Seattle, Washington. The agency also operates a national training center at its Ashburn facility. History The origin of the NTSB was in the Air Commerce Act of 1926, which assigned the United States Department of Commerce responsibility for investigating domestic aviation accidents. Before the NTSB, the Federal Aviation Administration's (FAA; at the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tamiami Canal
The Tamiami Canal or C-4 Canal, is a canal located in southern Florida in the United States. It flows in a west to east direction from the western part of the state in the Everglades past the Miami International Airport to a salinity control center near the Miami River. It averages in depth and is over wide in some areas. In 2019, a worm-shaped amphibian caecilian, ''Typhlonectes natans'', was found living in the canal. Normally found in Venezuela and Colombia, its capture was the first record of a caecilian in the United States.

Saffir–Simpson Scale
The Saffir–Simpson hurricane wind scale (SSHWS) classifies hurricanes—which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms—into five categories distinguished by the intensities of their sustained winds. This measuring system was formerly known as the Saffir–Simpson hurricane scale, or SSHS. To be classified as a hurricane, a tropical cyclone must have one-minute-average maximum sustained winds at 10 m above the surface of at least 74 mph (64 kn, 119 km/h; Category 1). The highest classification in the scale, Category 5, consists of storms with sustained winds of at least 157 mph (137 kn, 252 km/h). The classifications can provide some indication of the potential damage and flooding a hurricane will cause upon landfall. The Saffir–Simpson hurricane wind scale is based on the highest wind speed averaged over a one-minute interval 10 m above th ...

Cable-stayed Bridge
A cable-stayed bridge has one or more ''towers'' (or ''pylons''), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly. Cable-stayed bridges were being designed and constructed by the late 16th century, and the form found wide use in the late 19th century. Early examples, including the Brooklyn Bridge, often combined features from both the cable-stayed and suspension designs. Cable-stayed ...

Accelerated Bridge Construction
Rapid bridge replacement or accelerated bridge construction (ABC) is a technique that allows bridges to be replaced with minimum disruption to traffic. The replacement bridge is constructed on a site near the bridge to be replaced. When it is completed, the old bridge is cut away and removed using self-propelled modular transporters (SPMTs). Then the SPMTs lift the new bridge, transfer it to the work site and put it in place. Often the highway or railroad carried by the bridge is closed for just one weekend. Conventional techniques typically replace half a bridge at a time, with all highway traffic redirected under the other bridge half, often for a year or more, while construction progresses. Accelerated bridge construction (ABC) alternatives consist of ABC components and ABC techniques. Components can be categorized into prefabricated bridge elements (e.g. beams, bridge decks, footings, columns, pier caps, abutments etc.) or prefabricated bridge systems (e.g. bridge modules with s ...

Florida Department Of Transportation
The Florida Department of Transportation (FDOT) is a decentralized agency charged with the establishment, maintenance, and regulation of public transportation in the state of Florida. The department was formed in 1969. It absorbed the powers of the State Road Department (SRD). The current Secretary of Transportation is Jared W. Perdue. History The State Road Department, the predecessor of today's Department of Transportation, was authorized in 1915 by the Florida Legislature. For the first two years of its existence, the department acted as an advisory body to the 52 counties in the state, helping to assemble maps and other information on roads. The 1916 Bankhead Act passed by Congress expanded the department's responsibilities and gave it the authority to: establish a state and state-aid system of roads, engage in road construction and maintenance, acquire and own land, exercise the right of eminent domain, and accept federal or local funds for use in improving roads.

United States Department Of Transportation
The United States Department of Transportation (USDOT or DOT) is one of the executive departments of the U.S. federal government. It is headed by the secretary of transportation, who reports directly to the President of the United States and is a member of the president's Cabinet. The department's mission is "to develop and coordinate policies that will provide an efficient and economical national transportation system, with due regard for need, the environment, and the national defense." History Prior to the creation of the Department of Transportation, its functions were administered by the under secretary of commerce for transportation. In 1965, Najeeb Halaby, administrator of the Federal Aviation Agency (predecessor to the Federal Aviation Administration, FAA), suggested to President Lyndon B. Johnson that transportation be elevated to a cabinet-level post, and that the FAA be folded into the DOT. It was established by Congress in the Department of Transportation Act ...

Transportation Investment Generating Economic Recovery
Rebuilding American Infrastructure with Sustainability and Equity (RAISE), previously called Better Utilizing Investments to Leverage Development (BUILD), and Transportation Investment Generating Economic Recovery (TIGER), is a supplementary discretionary grant program included in the American Recovery and Reinvestment Act of 2009. The legislation provided $1.5 billion for a National Surface Transportation System through September 30, 2011, "to be awarded on a competitive basis for capital investments in surface transportation projects". Requirements The U.S. government designed TIGER grants in order to incentivize bettering environmental problems and reducing the United States' dependence on energy. On the economic front, the United States hopes infrastructure investment will encourage job creation, a pressing political priority; this would likely require the project to be shovel-ready.
