摘要：	The largest span of the road over bridge at Majherhat Kolkata catastrophically collapsed on September 4, 2018, injuring several and killing three people. Although the structural system of this bridge was conceived and designed 57 years back, it is unique in nature. The bridge superstructure consists of a both way precast pre-stressed concrete girder arrangement with nominally reinforced concrete bridge deck. The sustainability of this attractive type of structural system is among the current research areas in the world. Main objective of this paper is to identify the probable events which are primarily responsible for the bridge structural system failure through the use of fault tree analysis. A study of uniqueness and its behaviour have been carried out to identify the probable causes of this failure with some post failure supporting evidence gathered from site. This report aims to provide a guideline for detail analysis of the failure with available forensic engineering evidences.
