Bridge aqueduct of kharanagh district

 
This ancient monument enjoys the great antiquity of ten centuries and is made of stone and mortar. Since the appearance of the qanat and the farming lands are separated by a canyon, this bridge facilitates the water transmission process.
Gradual water seepage through the bridge brought about the collapse of the ceiling which has recently been restored by improvising a canal syphon made of stone, mortar and ceramic along the passage for water conveyance process. (the remains of the monument indicate that the syphon had once been 30 meters long). Regretfully, a distructive flood damaged the syphon and ruined a portion of the bridge wall which set the authorities to rehabilitating the structure applying a resistant brick being used at the time being.
