Views of Victoria Falls. Behind, the bridge between Zambia and Zimbabwe.  For more than 50 years the bridge was crossed regularly by passenger trains as part of the principal route between the then Northern Rhodesia, southern Africa and Europe. Freight trains carried mainly copper ore (later, copper ingots) and timber out of Zambia, and coal into the country. The age of the bridge and maintenance problems have led to traffic restrictions at times. Trains cross at less than walking pace and trucks were limited to 30 t, necessitating heavier trucks to make a long diversion via the Kazungula Ferry or Chirundu Bridge. The limit was raised after repairs in 2006, but more fundamental rehabilitation or construction of a new bridge has been aired. During the Rhodesian UDI crisis and Bush War the bridge was frequently closed (and regular passenger services have not resumed successfully). In 1975, the bridge was the site of unsuccessful peace talks when the parties met in a train carriage poised above the gorge for nine and a half hours. In 1980 freight and road services resumed and have continued without interruption except for maintenance. Today one of the Victoria Falls Bridge's main attraction are historical guided tours focusing on the construction of the bridge and which include a walking tour under the main deck. On the Zambian side there is a small museum about the bridge which is free to enter and contains cafe selling refreshments. Also located on the bridge is the Shearwater 111 metres (364 ft) bungee jump including a bungee swing and zip-line. Concerns about safety of the attraction were raised in late 2011 after the bungee's cord snapped and a young Australian woman fell 24 metres (79 ft) into the fast flowing river with many crocodiles. The bridge was originally referred to as the Great Zambesi or Zambezi bridge, later becoming known as the Victoria Falls Bridge.
