Work to build a new bridge some 300 km south of Khartoum, on the main road linking Sudan to the Red Sea, started in 1975. The bridge was built close to an existing railway bridge 900 metres further north, to allow heavy vehicles to travel between Rabak on the west of the White Nile and Kosti, on the east. The bridge, with 21 spans in prestressed reinforced concrete and 1.5-metre diameter piled foundations, was completed in 1979. It has two, four-lane carriageways and two footpaths. It is 19 metres wide and 1,082 metres long. This bridge won the Ingersoll-Rand Italia prize in 1981.
