About Morbi Bridge (popularly called the jhoolta pool)

  • Built in 1887 during the reign of Waghaji Thakor, who ruled Morbi from 1870 to 1922, to connect Darbargadh (palace) and Nazarbaug over the Machchhu river.

  • Material for this bridge was imported from England and fabrication of the bridge was done by the Mumbai-based engineering company Richardson and Cruddas.
  • The bridge was 765 feet long and about four feet wide.
  • Unique Bridge: It was a suspension bridge — a type in which the deck is hung below suspension cables on vertical suspenders.
    • Even the Howrah bridge in Kolkata or the Lakshman Jhula in Rishikesh are not suspended bridges, which makes the Morbi bridge very unique.
  • The Golden Gate Bridge and Brooklyn Bridge in the US are examples of suspension bridges.
  • India’s longest single-lane motorable suspension bridge — the 725-metre Dobra-Chanti suspension bridge built over the Tehri Lake — was inaugurated in November 2020.
