The Bridge of Allahverdi Khan across the Zayandeh Rud is a continuation of Chahar Bagh, the principal street in Isfahan. Built at the beginning of the 17th century at the order of Shah Abbas, it is named after the general-a famous war- chief- who was put in charge of the work. It is also called the Bridge of 33 Arches, or SioSe Pol.
It is 45 feet wide and 175 yards long but- although it is impressive looking- it does not have the same archaeological or aesthetic interest as the two other bridges farther downstream.
This bridge is located in the southern end of Chahar Bagh Avenue in Isfahan and was named after its founder. It is also known as Jolfa bridge
The bridge is made of bricks and stones. It is 295 meters long and 13.75 meters wide. It is said that the bridge originally comprised 40 arches however this number gradually reduced to 33.
According to numerous historical references concerning the buildings constructed during Shah Abbas the Safavid in Isfahan, it is so conceived that the construction work of this bridge was completed concurrent with the construction of Chahar Bagh in 1596. This bridge is called Si-o-Se Pol (in Farsi meaning 33 bridges) because it embraces 33 arches.
