Malan Bridge, also called Pul-i-Malan (Dari: پل مالان), is a two-lane arched bridge over the Hari River, connecting Injil District with Guzara District, both in Herat Province of Afghanistan. It was built around 1110 AD. The bridge is located 12 km (7.5 mi) south of Herat's old city and downstream or west from Pul-i Pushtu. It is currently made up of 22 arches and has survived several floods that have washed away other bridges crossing the Hari. It is 230 m (750 ft) long, 8 m (26 ft) wide, and 10 m (33 ft) high.
