Abstract: Mumbai-Pune Expressway is the Indias first six-lane concrete; high speed highway. The expressway is 93.0 km in length and has been utilized by 43000 vehicles in a day. In year 2004; the expressway suffered from rockfall problem and 17 locations hit by the rockfall. The rockfall may cause damage; injury and death to the users of these passageways. So a quantitative risk assessment (QRA) has been needed to identify the risk present along this expressway. Three cases have been studied for the risk assessment and it has been identified that the most prone case is case-2 where the risk to the loss of life is equal to 6.84*10-2.
