The river is 250–400 m wide in this area, and though in the dry season it may be conf

The Great East Road runs for most of its length on watersheds at an elevation of around 1000 m, but the river is at an elevation of 390 m at the bottom of the valley. The bridge approaches have to contend with steep rugged slopes and deep ravines covered in forest or thick bush; the area is remote and about 250 km from the nearest city, Lusaka. The First Luangwa Bridge was built in Zambia's colonial era in 1932 as a narrow 300 m long wide steel and reinforced concrete deck on concrete piers and columns, financed, like the Chirundu Bridge and Beit Bridge by the Beit Trust.
