This fine old 22-arched bridge is a few kilometres south of the city, visible from the road when driving from the airport. Believed to have been constructed by the Seljuks in the early 12th century, it has survived the floods that have washed away countless other bridges on the Hari Rud. According to legend, two sisters, Bibi Nur and Bibi Hur, collected egg shells to mix with the clay of the bricks, making the structure stronger than steel. It's no longer used for motor traffic, but is worth a visit for its picturesque setting.
