Bridges

The bridges over the Zayanderud comprise some of the finest architecture in Isfahan. The oldest is the Shahrestan Bridge, whose foundations were built during the Sasanian Empire (3rd–7th century Sassanid era); it was repaired during the Seljuk period. Further upstream is the Khaju Bridge, which Shah Abbas II built in 1650. It is 123 metres (404 feet) long, with 24 arches; and it also serves as a sluice gate.

Another bridge is the Choobi (Joui) Bridge, which was originally an aqueduct to supply the palace gardens on the north bank of the river. Further upstream again is the Si-o-Seh Pol or bridge of 33 arches. It was built during the reign of Shah Abbas the Great by Sheikh Baha'i and connected Isfahan with the Armenian suburb of New Julfa. It is by far the longest bridge in Isfahan at 295 m (967.85 ft).

Another notable bridge is the Marnan Bridge.
