When designing large structures such as bridges, ships, dams and various modes of transportation, engineers must determine what methods and materials should be used in order to design, construct, and maintain the structure for a long period of time. A strict code of ethics must be followed in order to reduce any possible damages and tragedies. Though this process is used to try and minimize any design errors and possible failures, unknown factors such as population increase, natural disasters,
Section 5: I-35W Bridge Collapse Case Study On August 1, 2007 at approximately 6:05 p.m. 1,064-foot section of the 1,907-foot long I-35W highway bridge collapsed into the Mississippi River. This catastrophic failure of the main bridge span resulted in the death of 13 people and injuring 145 others. In total, 111 documented vehicles were on the bridge at the time that it collapsed. Included in this total are 25 construction vehicles. On the day of the collapse, the bridge was undergoing a resurfacing
The title of the article is “Bridge Collapse in Minneapolis Kills at Least 7”. The author of the article is Libby Sanders and Susan Saulny. The main idea of this article is that a interstate highway bridge in Minneapolis crashed 60 feet into the Mississippi River. At least 50 vehicles and people were sent into the water. Sources say that at least 7 people were killed and over 60 more we injured. The author explains that the bridge 1000 foot bridge was under construction repairing the bridge’s concrete

Approximately after 6 p.m. at the end of rush hour, Interstate 35W bridge, known as one of the busiest interstates in Minneapolis, collapsed dropping into the Mississippi river. This incident killed 13 people and injured 145 others. As the first responder, you have to be able to handle the unexpected. I had to provide direction and make important decisions during this awful tragedy. When I received this phone call, I was at dinner with friends. I was in immediate shock; you never know what to expect when
This essay will review major bridge collapses, and how they were resolved to improve the design of future bridges. The two main causes of bridge failure, wind loads and improper design or design flaws, will be discussed with examples like the Tacoma bridge collapse of 1940 and the I-35 Mississippi River bridge collapse of 2007 later on in the paper (4, 1). Although these are the two usual causes of bridge collapse there are also many other reasons for bridge failure such as, corrosion by environment
American infrastructure is aging, fast. Roads and bridges are failing, entire sections of the US and Canada have had lost power, effecting approximately 55,000,000 people, due to lack of tree maintenance, and many of the sewer and water lines in cities like New York are over 100 years old (Markowitz; Minkel). According to the American Society of Civil Engineers (ASCE) in 2013, the United States infrastructure network earns a grade of a D+, and requires a $3.6 trillion dollar investment by the year
