In the article, “I-5 and the Physics of Bridge Collapse,” Hartsfield (2013) has stated that most bridges including the I-5 bridge failed due to inevitable design flaws. The author implies that an optimal bridge design relies on the considerable factors of a project such as cost and timeline. The author also quotes the possibilities that can cause a bridge to collapse including prolonged lifespan, construction errors and miscalculations. According to Hartsfield (2013), “A truss bridge holds as long as the beams themselves don’t break and the joints stay together.” In this regard, once a part of the structure beam is hit, it can cause a bridge to fail. He further states that the unfortunate tragedy of the I-5 truss bridge might have been due to the impact caused by a truck as it crashed into one of the truss beams. Hartsfield also mentions that nevertheless, it is critical to understand the problem in order to determine the actual cause of unpredicted collapse in bridges.
