Question: Information: - Namibia, officially the Republic of Namibia (German: ), is a country in southern Africa whose western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although it does not border Zimbabwe, a part of less than 200 metres of the Zambezi River (essentially a small bulge in Botswana to achieve a Botswana/Zambia micro-border) separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek, and it is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU), and the Commonwealth of Nations. - The Republic of Zambia is a landlocked country in Southern Africa, neighbouring the Democratic Republic of the Congo to the north, Tanzania to the north-east, Malawi to the east, Mozambique, Zimbabwe, Botswana and Namibia to the south, and Angola to the west. The capital city is Lusaka, in the south-central part of Zambia. The population is concentrated mainly around Lusaka in the south and the Copperbelt Province to the northwest, the core economic hubs of the country. - The Luangwa River is one of the major tributaries of the Zambezi River, and one of the four biggest rivers of Zambia. The river generally floods in the rainy season (December to March) and then falls considerably in the dry season. It is one of the biggest unaltered rivers in Southern Africa and the 20,000 square miles (around 50,000 square kilometers) that make up the surrounding valley are home to abundant wildlife. - The Zambezi (also spelled Zambeze and Zambesi) is the fourth-longest river in Africa, the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa. The area of its basin is , slightly less than half that of the Nile. The rises in Zambia and flows through eastern Angola, along the eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it crosses the country to empty into the Indian Ocean. - The Luangwa Bridge is the only large bridge and the principal engineering challenge on Zambia 's Great East Road , crossing the lower Luangwa River where it flows from the Luangwa Rift Valley into the Zambezi valley . The river is 250 -- 400 m wide in this area , and though in the dry season it may be confined to a shallow channel meandering across sandbanks , at the end of the rainy season any bridge has to be able to withstand a full - width , deep and fast - moving flood . 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 . Its proximity to Mozambique ( about 2 km ) and Rhodesia ( 60 km ) , as well as its status as the only access point within the country for Zambia 's Eastern Province , makes it strategically vulnerable in any conflict . After Zambia 's independence in 1964 , President Kenneth Kaunda 's support for freedom fighters in neighbouring countries led to the bridge being destroyed in revenge . The Second Luangwa Bridge ( opened in 1968 ) was built quickly above the first , with aid from Britain which had been the colonial power in Zambia . It is a cable - stayed bridge designed by Freeman Fox & Partners and built by the Redpath Dorman Long . It has a composite steel - reinforced concrete deck 9.8 m wide , two H - shaped steel pylons 42 m tall on two reinforced concrete piers , and steel cables . The main span is 222 m with approach spans of 40 m each . In 1979 the military of Zimbabwe - Rhodesia destroyed the bridge as well as the Chambeshi road and rail bridges in... - Africa is the world's second-largest and second-most-populous continent. At about 30.3 million km (11.7 million squaremiles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4 % of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two "de facto" independent states with limited or no recognition. - The Nile ("en-Nl", "an-Nl" "P(h)iaro"; Ancient Egyptian:"'p" and "Iteru"; Biblical Hebrew: , "Ha-Ye'or") is a major north-flowing river in northeastern Africa. It is generally regarded as the longest river in the world, however other conflicting sources cite a 2007 study that gave the title to the Amazon River in South America. The Nile, which is 6,853km (4,258miles) long, is an "international" river as its water resources are shared by eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, Congo-Kinshasa, Kenya, Ethiopia, Eritrea, South Sudan, Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan. - Zimbabwe, officially the Republic of Zimbabwe, is a landlocked country located in southern Africa, between the Zambezi and Limpopo Rivers. It is bordered by South Africa to the south, Botswana to the west and southwest, Zambia to the northwest, and Mozambique to the east and northeast. Although it does not border Namibia, less than 200 metres of the Zambezi River separates it from that country. The capital and largest city is Harare. A country of roughly 13 million people, Zimbabwe has 16 official languages, with English, Shona, and Ndebele the most commonly used. What entity does 'luangwa bridge' has the relation 'crosses' with?
Answer:
zambezi river
