STORYLINE
After the recent bridge collapse in Pittsburgh, Bowman says that his first thoughts were on factors that could lead to structural failure. As a bridge ages, the condition of the structure deteriorates. Natural disasters, vehicle accidents and mistakes during construction or maintenance of the bridge can all lead to a collapse. These can occur regardless of the age of the bridge, but older bridges can be more susceptible. To prevent this, Bowman says that bridges are inspected frequently. Following a bridge collapse in 1967, Congress passed a rule stating that all bridges had to be inspected on a two-year cycle. Bowman says that while bridge collapses do occur, it is not a common event. He does not think drivers and pedestrians need to worry about traveling over bridges.
