The problems for Zambia did not emerge for another 50 years, with the Katanga crisis of 196063. The Pedicle cuts off the Luapula Province and the western part of the Northern Province from the country's industrial and commercial hub of the Copperbelt. This is exacerbated by the fact that at the Pedicle's toetip, where the Luapula River ostensibly flows out of the Bangweulu system, the river swamps are at least wide and the floodplain is wide, making a road impossible with the resources available for most of the 20th century. The most southerly road possible into Luapula keeping to Zambian territory was pushed, by these circumstances, another north, going around Lake Bangweulu.
