This roadway bridge near Vondh (as well as many other bridges in Gujurat) were damaged by the 2001 M7.6 Bhuj earthquake. It was an interplate boundary earthquake caused by India's movement north into Asia. A similar event in 1819 caused the Indus River to change its course.
This railroad bridge is just a pair of steel girders that supports ties and rails. No bridge deck and no ballast. Apparently such a minimalist approach works since one percent of India's population (over 10 million people) travel by rail every day.
