Overview
This course is specifically designed for Ohio-licensed engineers to qualify as a "timed and monitored" online course. The course contains an automatic timer that prevents the user from accessing the quiz and earning a certificate of completion until the minimum amount of study time has been met. This achieves the Ohio Board's intent that an online course should be "paced" by the provider. For more information, please see the Ohio state requirements. This course may also be accepted in other states (see the "Board Acceptance" tab above). However, if you are not licensed in Ohio, it is suggested that you purchase the self-paced version of the course.

In Engineering Ethics: The Minnesota I-35W Bridge Collapse , you'll learn ...

  • The original bridge design and design errors that led to the disaster
  • The important role of quality control procedures for designing, reviewing, and approving bridge design plans and calculations
  • The responsibilities of engineers as they relate to public safety, regulatory authorities, and liability issues

On August 1, 2007, the I-35W Bridge over the Mississippi River in Minneapolis, Minnesota collapsed during evening rush hour, plummeting into the river and onto the concrete embankment below. At the time of the collapse, traffic was congested from normal rush hour traffic and fans headed to the Twins game. In some places the cars were bumper to bumper, their progress constrained by two lanes closed for construction. In all, 111 vehicles were on the collapsed part of the bridge, along with members of the construction crew working on the bridge, their equipment, and supplies. The disaster killed 13 people and injured 145 more, and the loss of an important interstate bridge had a major impact on the Minneapolis economy.

Perhaps one of the most striking things about the Minneapolis I-35W bridge collapse is that an engineer made a critical error in the design of a steel truss bridge more than 40 years before the disaster and for more than 40 years the error and the symptoms of the impending failure of the bridge component were never properly identified or addressed. Not one member of a quality control team or any safety system in place at the time addressed the source of the error or heeded the warning signs of the impending disaster. Despite state and federal guidelines and regulations, the Minnesota Department of Transportation (Mn/DOT); Mn/DOT inspectors; and engineering groups hired to inspect the bridge all failed to act. As a result, the engineering design and inspection firms, the construction company working on the bridge at the time of collapse, and the State on Minnesota all faced enormous liability issues.

This course reviews the analyses made by the National Transportation and Safety Board (NTSB) and other sources in order to familiarize the reader with the design errors that led to the disaster. It also examines the failures of the quality control process; insufficient bridge inspections; and deficiencies within the state and federal specifications and guidelines that caused the impending failure of the bridge connectors to be overlooked for more than 40 years after the initial design. The course will also discuss the responsibilities of engineers as they relate to public safety, regulatory authorities, and liability issues.
