context_section_description: The Cairo-Cape Town Highway, Highway 4 in the Trans-African Highway network, runs between the northern town of Namanga on the Kenyan border and the Zambian border town of Tunduma in the southwest, via Arusha, Dodoma, Iringa, and Mbeya. The section between the entrance to Tarangire National Park and Iringa has been recently paved between Babati-Kondoa-Dodoma-Iringa. There is no longer a need to traverse a longer eastern route from Arusha to Iringa via Moshi and Morogoro is paved. This route is 921 kilometres (572 mi) versus 689 kilometres (428 mi) for the Arusha-Dodoma-Iringa route.
  In the southwest, from Iringa to Tunduma, the Cairo-Cape Town Highway follows the Tanzam Highway linking Zambia and Dar es Salaam.
