The I-35W Bridge, located in Minneapolis, Minnesota, was a bridge that opened in November of 1967 and was designed by Sverdrup & Parcel and Associates, Inc. The bridge had a truss arch design that spanned a total distance across the Mississippi River of 1907 feet. Also, the bridge was a deck truss which means the roadway was located on top of the truss itself. With a total of 4 piers, 2 on either side of the Mississippi River, that supported the bridge, the I-35W Bridge crossed the Mississippi River in 3 main spans; the longest span, which was located directly above the river, was 458 feet long. On August 1, 2007, the I-35W Bridge collapsed and sent the 80+ vehicles on the bridge into the Mississippi River.
The reason for the collapse was due to a design error made by Sverdrup & Parcel and Associates, Inc. A design error is a mistake or human error that was made any time before the production process in a structure’s blueprints. Design errors can injure as well as kill people, and it is the job of the designer to ensure the safety of the people. By rechecking and revising the whole d...
Without a concrete reason for the bridge's failure, every suggested reason was researched until proven incorrect” (Silver). There were many reasons that were suggested, but could not be proven correct due to the collapse. Wikipedia states that “A small crack was formed through fretting wear at the bearing, and grew through internal corrosion, a problem known as stress corrosion cracking.” The failure of the bridge was caused by a defect in one of the eye-bars on the north side causing the other side to collapse as well. “Stress corrosion cracking is the formation of brittle cracks in a normally sound material through the simultaneous action of a tensile stress and a corrosive environment.
...afety should have inspected the building prior to issuing permits for further renovation, especially knowing this structure was going to be housing 124 residents. It seems that lack of knowledge from prior owners and lack of responsibility of city officials are responsible for this collapse and sadly, the loss of 9 brave men in the line of duty. The Boston Fire Department could have worked closer with the owner/ construction crew at the Hotel Vendome, and the deficiencies would have been found, and they would have known the instability they were walking into on June 17. At that point, firefighting operations would have more than likely been defensive. The firefighters did not conduct pre-incident planning which would have let them know they were going to face the construction barriers while attempting to lay hose, maneuver hose, and get the hose to a water source.
It became a link between Fort Erie, Canada and Buffalo, New York. The bridge is over one mile long, 5,800 feet, and holds three lanes of traffic. The center lane may go north or south depending on the volume of traffic. In 1934, the Great Depression caused a change.
Out of all the stories I have read in class so far, An Occurrence at Owl Creek Bridge by Ambrose Bierce, has touched me most. When I first began reading the story I felt as though I was not interested, because my assumptions of what the story was going to be about were completely different than the stories actual content. As I set aside my judgment and let myself try to enjoy the story, I found myself anxiously reading to the bitter end. This story was not only interesting and unique, but also had an added twist at the end, which surprised most readers. Depending on how observant the reader is with picking up on foreshadowing and symbolic meaning, one may realize before the final sentences that Peyton Farquar was not actually escaping home but in fact hallucinating while desperately trying to escape the hangmen.
The Bailey Island Bridge is located in Harpswell, Maine on Route 24. Before the making of the bridge, the fishermen that lived on Bailey’s Island wanted a bridge that connected their island to Orr’s Island. The town of Harpsweell made and voted on their decisions in the weekly town meetings (“Bailey”). The project was stalled because of some of the mainlanders in the town, but it was brought back up for discussion in 1912. They first agreed on a “road” which would connect the two islands and would be constructed with timber. This was to cost $3,000. The cost quickly reached $25,000 at a later town meting because they decided to build the bridge with stone and concrete instead. Once the legislature decided to pass a bill stating that it would fun state’s highway and bridge projects, they decided to move forward with the project (Hansen, 36).
The failure tragically occurred on the night of the dance party, with the added weight of all of the partygoers proving too much for the supporting bolts to handle. At 7:05 P.M. one of the upper walkway’s supporting bolts failed causing the rest of the connections to break and “unzip” (Chronology). The upper walkway crashed onto the lower walkway causing both to fall onto the lobby floor below. Numerous key factors are often cited as having left the construction project vulnerable to such fatal design flaws.
The Jericho Covered Bridge in Kingsville, Maryland was built in 1865 and restored in 1982. The bridge is 100 feet long and cased in cedar planks and timber beams. Legend has it that after the Civil War many lynchings occurred on the bridge. Passersby were supposedly captured on the bridge and hung from the upper rafters. The bridge is very close to my house and I have driven over it several times. The storyteller, age 19, also lives a couple minutes away from the bridge. He has lived in Kingsville, Maryland his entire life. He recalled a dramatic story he had heard from his older brother involving the haunted bridge.
The 1890 story “An Occurrence at Owl Creek Bridge” by Ambrose Bierce was composed with a structure that shows time fluidity. The story illustrated the perceived function of time as beyond reality as it slows down to the satisfaction of the delusions of protagonist, Peyton Farquhar, as he experiences a dying incident on the day of his execution. Farquhar was charged with the crime of an attempted act to destroy or sabotage the Owl Creek Bridge, and was thereafter sentenced to death by the Federal Army. Farquhar believes as he also leads the readers the same that he has escaped execution and has made his way back home. The dying protagonist’s experience was portrayed in a slow flow of time that seemed to exactly fit the many circumstances that occurred just in time for reality to come and take its place in time.
When I was a small child, I remember my parents crossing the James River on the ferry in Surry County while taking my brother and me to Jamestown. At the time, I thought it was thrilling to ride the ferry. It was fun to stand out at the bow and watch as we went over the river to the other side where the boats are docked at Jamestown. We fed the birds on the front deck, and I also remember going up into the top of the ferry where they had a seated area that allowed someone to get out of the wind and still be able to see out. As an adult, I no longer have this glowing admiration for the ferry services in Surry. It never fails that when I am approaching the dock; the ferry is pulling away. Thereafter, it will be at least a thirty-minute wait for the next ferry to arrive. As well as, the actual ride across which could be an additional thirty minutes depending on which ferry pulls into the dock. One ferry is extremely slower than the other is. I will go to great lengths to avoid the ferry services to cross the James River to Williamsburg and will rather drive around Newport News than to use the ferry. My husband and I moved to Surry County two years ago, and it would be nice to be able to travel safely to Williamsburg without the added time it takes to cross the James River on the ferry. There has been talk over the years about replacing the ferry services with a bridge; however, those notions are always disregarded. The residents of Surry County would be better served if a bridge were put in place of the ferry at Scotland Wharf.
“An Occurrence at Owl Creek Bridge”, to me was about a man swindled into being killed. Before you die, your whole life flashes before your eyes. But for this man, it was not his life, but what could’ve happened instead of him dying being played out in his mind. Peyton Farquhar was a slave owner from Alabama that highly supported the south.
After long and heated arguments between experts, it was decided that the Superintendent of Construction was extremely inexperienced, and that there was "recklessness in the handling of public money," on the part of the Treasury Department and the Immigration Bureau of Officials. The entire building, excluding the hospitals, had been built shoddily. After news of the problems with the building had been in the media, a lot of people involved with the construction of the building resigned their positions.
On December 29, 1876, a train was crossing over a railroad bridge spanning the Ashtabula River when the entire bridge collapsed, sending most of the train into the frigid water below. This disaster would be the deadliest bridge disaster in the United States. Investigators quickly tried to determine why this bridge, after eleven years of service, collapsed. The investigators would ultimately place the blame on the president of the Ashtabula Railroad Company, Amasa Stone. The bridge was constructed with many flaws, both known and unknown. This disaster would lead to people realizing the need for structural standards for bridges and qualified engineers.
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.)
In the early 1900's, settlers of the San Francisco Bay Area considered the San Francisco-Oakland Bay Bridge, which spans over eight miles long and 500 feet above the water at its highest point, an impossible feat. However, with only a few complications, the bridge was completed by November, 1936. The San Francisco-Oakland Bay Bridge consists of two bridge types. The east section is a cantilever bridge, and the west, a suspension bridge.
Over the East River in New York City stands the Brooklyn Bridge, connecting the Brooklyn and Manhattan boroughs. From end to end, the bridge spans 6,016 feet and weighs a heavy 14,680 tons. Ever since construction on the Brooklyn Bridge was completed in 1883, the bridge has offered a safe route with scenic views to tens of thousands of tourists and commuters who have traveled it via train, car, pushcart, and bicycle. The history behind the Brooklyn Bridge is definitely intriguing as well as important because many fatalities occurred in the construction process, including one which occurred before construction on the bridge even started. Also, a lot of workers, time and money were used in building the bridge. In addition,
