Diyala Bridge
Diyālá
Diyala Weir, also known as Diyala Barrage, is a diversion dam located on the Diyala River approximately 90 kilometers northeast of Baghdad, Iraq. Constructed between 1966 and 1969, the weir was built to divert water from the Hemrin Dam, situated 11 kilometers upstream, into the Khalis and Sadr Al-Mushtarak canals for irrigation purposes. The structure was designed by the Consulting Engineers Sir Murdoch McDonald and Partners from London during the 1960s. It features road bridges at each end, engineered to withstand heavy military loads such as tanks on wheeled transporters, designed by Captain B P Daly of the Royal Engineers. The weir is integral to a large irrigation scheme that supports agricultural activities in the region. It has also been commemorated on Iraqi postage stamps, highlighting its importance as an infrastructural landmark.

Historia
The Diyala Weir was constructed between 1966 and 1969 as part of a major irrigation project designed in the 1960s to improve water management on the Diyala River.
It was built to divert water from the Hemrin Dam into irrigation canals to support agriculture downstream.
The design and construction involved British consulting engineers and military engineers, reflecting international collaboration.
Over the decades, it has remained a key water management structure in the region.
