Sukkur , or Sakharu ( formerly Aror (Sanskrit: अरोड, Urdu: اروڑ), is the third largest city of Sindh province, situated on the west bank of Indus River in Pakistan in Sukkur District. One conjecture is that when Arabs invaded Sukkur (Sindh) in the 8th century, they found an extreme climate (hot and cold), and called it Saqar, which means intense.However, the word Sakharu in Sindhi means "superior", which the spelling of the city's name in Sindhi suggests is the origin of the name. Sukkur is nicknamed Darya Dino (درياءَ ڏنو, meaning the gift of river), as without the Indus the city would be a desert.
Sukkur shares its border with India (Jaisalmer, Rajasthan).The Sukkur Barrage has 66 Gates. The Sukkur barrage (formally called Lloyd Barrage), built under the British Raj on the Indus river, controls one of the largest irrigation systems in the world. Construction of the bridge was started in 1923 and completed in January 1932.
