CHAPTER 3 BRIDGE FAILURE STUDIES AND SAFETY ENGINEERING 77
Figure 3.1 School children visiting the site of a railway bridge failure in India in
2005. The bridge was washed by fl oods causing the deaths of 114 people.
• Landmark or historic bridges have improved inspection and maintenance and last longer
than other old bridges of the same era.
• Failure of new bridges––These are relatively few but occur due to design or construction
errors.
4. Design deficiency leading to bridge collapse: In 2007, a newly built prestressed concrete
curved girder bridge collapsed in Karachi, Pakistan during rush hour killing over a dozen
people and injuring dozens more (Figure 3.2).
Figure 3.2 Immediately after recent collapse of the bridge in Karachi,
ambulances assemble to carry the injured to hospitals.
