Fortunately the only loss of life was a dog since the man in the car escaped while unfortunately the dog wouldn't leave so there was no collateral damage from that on October 14, 1950 a new bridge was made to replace it and is currently the fifth largest bridge in the US but fortunately the collapse boosted research on bridge aerodynamics and on July 2007 a second bridge that ran parallel to the first was opened.
But whose fault was it?
2 weeks after a newspaper headline story saying that David Glenn (the PWA’s field engineer) submitted a warning of errors in the design of the bridge and wouldn’t recommend accepting the bridge he was fired by the PWA. But the Washington State
Steven Hermosillo Professor Wallace Fire Tech 105 15 November 2015 Silver Bridge Collapse According to Wikipedia, Forty-six people were killed in the silver-bridge collapse and another nine people were injured. “The Silver Bridge was an eye-bar-chain suspension bridge built in 1928 and named for the color of its aluminum paint. The bridge connected Point Pleasant, West Virginia, and Gallipolis, Ohio, over the Ohio River” (Wikipedia). This was a highly used bridge serving thousands of cars a day before the collapse.
The Peace Bridge became publicly owned. As a result there were no taxes to be paid, and financing for projects could be obtained by issuing bonds at a low interest rate. The publicly owned bridge instituted a board of governors called the Peace Bridge Authority, PBA. The board, which made all decisions, was made up of six Americans and three Canadians. From that time until 1996 there were few changes made.

On May 24, 1854, construction began of the Victoria Bridge. This was a difficult task for the workers given the size of the bridge (“almost two miles in length from shore to shore” ) was the largest construction project during this period of time. Moreover, the construction of the bridge did not cease during the winter months. Therefore, many of the workers on the bridge would continue even while the St-Lawrence River froze underneath their
The first and most challenging problem associated with building the Mackinac Bridge arrived long before the bridge was even designed. Financing such an enormous project was no easy feat. In 1928, the idea of connecting the upper and lower peninsulas was proposed to Congress for the first time (Brown 4). At the time, the suspected bridge project was very much under government scrutiny and control. In fact, the initial boost in interest in pursuing the construction of a bridge came about due to the depression. The Public Works Administration (PWA) had been created under President Franklin D. Roosevelt’s New Deal economic plan which would fund certain construction projects with th...
The Tacoma Narrows Bridge is perhaps the most notorious failure in the world of engineering. It collapsed on November 7, 1940 just months after its opening on July 1, 1940. It was designed by Leon Moisseiff and at its time it was the third largest suspension bridge in the world with a center span of over half a mile long. The bridge was very narrow and sleek giving it a look of grace, but this design made it very flexible in the wind. Nicknamed the "Galloping Gertie," because of its undulating behavior, the Tacoma Narrows Bridge drew the attention of motorists seeking a cheap thrill. Drivers felt that they were driving on a roller coaster, as they would disappear from sight in the trough of the wave. On the last day of the bridge's existence it gave fair warning that its destruction was eminent. Not only did it oscillate up and down, but twisted side to side in a cork screw motion. After hours of this violent motion with wind speeds reaching forty and fifty miles per hour, the bridge collapsed. With such a catastrophic failure, many people ask why such an apparently well thought out plan could have failed so badly?(This rhetorical question clearly sets up a position of inquiry-which iniates all research.) The reason for the collapse of the Tacoma Narrows Bridge is still controversial, but three theories reveal the basis of an engineering explanation. (Jason then directly asserts what he found to be a possible answer to his question.)
Concepts –General Palmer Railroad was negligent and caused the death of John Goodson. Several factors attribute to negligence including insufficient operating regulations, lack of training for engineers and train crew, inadequate warnings at crossings and obstruction of the right of way view for both drivers and its train engineers. It is stated in the affidavit of the engineer that he did not see the truck until he passed the treeline. The treeline ends a ¼ mile before the grade crossing even though it takes ¾ miles for a train to stop. He admits he felt as if the truck was racing him and his first reaction was to blow the whistle instead of applying the brakes. This particular crossing had an accident 6 years prior so it should have been common sense for the engineer take extra precautions. According to exhibit 5, the Ralston Rd. had a diagnostic review on March 21st, 2006 and was scheduled to have gates installed in July of 2009. The review was about two months before the fatal accident involving John. This proves that Goodson Railroad knew the crossing needed improvement prior to the
Arnold & Porter chose to sue Pittston rather than the Buffalo Mining Company because the value of the corporation allowed for adequate compensation to the victims. Author and head lawyer for the plaintiffs, Gerald M. Stern, writes that the original goal was sue to sue for $21 million for the disaster to have a material effect on the cooperation (51). To avoid responsibility Pittston attempted to prove that the Buffalo Mining Company was an independent corporation with its own board of directors. The lawyers for the plaintiffs disproved this claim by arguing the Buffalo Mining Company never held formal meetings of the board of directors and was not independent of the parent company. During this case Pittston’s Oil division had applied to build an oil refinery in Maine. The ...
The construction site was in a downtown area of a large southeastern city, criss-crossed with city streets, utilities, and immediately adjacent to mid-rise and high rise buildings. Nearly all of the work was required to be constructed within temporary piling structures to limit settlement of adjacent structures. The construction contract called for seven phase releases of work areas and nine completion milestones, each milestone has its own liquidated damages penalty. The construction contract was valued at $10 million, and the duration was 545 calendar days. Following the completion of the work, the contractor filed a claim for $5.5 million and 1.1 million in interest. The authority subsequently denied the claim and the contractor, in accordance with the contract, filed an arbitration demand with the American Arbitration Association. Following the contractor’s issuance of the demand letter, the parties agreed to resolve the dispute through negotiation” (Ray,
In her essay,”Importance of the Golden Gate Bridge,” Stephanie Stiavetti suggest that “It maintained this point of pride for nearly 25 years until the Verrazano- Narrows Bridge was built in New York in 1964. Today, this historic San Francisco landmark holds its place as the second largest suspension bridge in the country, behind Verrazano Narrows.” Back then, experts thought that it would be impossible to build a bridge across the tides and currents in that area because strong currents and tides would make construction extremely difficult and dangerous. The water is over 500 feet deep in the center of the channel, and along with the area's strong winds and thick fog, the idea of building a bridge there seemed nearly impossible. Despite all of the problems of building a bridge across the Golden Gate, Joseph Strauss was named as lead engineer for the project. Construction began January 5, 1933, and in the end cost more than $35 million to

In the early morning hours on January 17th, 1994 a very violent tremble took place across Los Angeles, California area that left fifty-seven people dead, more than 7,000 injured, more than 20,000 homeless and left over 40,000 buildings damaged. Around 4:30 a.m. a horrific 6.7 magnitude earthquake, that tested building codes and earthquake-resistant construction, shook Los Angeles, San Bernardino, Ventura, and Orange Counties with the most intense damage occurring in Sherman Oaks and Northridge. The earthquake caused several bridges and overpasses to collapse closing sections of the Santa Monica Freeway, Simi Valley Freeway, Golden State Freeway, and the Antelope Valley Freeway. There were also several fire outbreaks throughout the San Fernando Valley, Malibu, and Venice area because of underground gas lines that had been ruptured during the earthquake that caused additional damage.
