The Walvis Bay-Ndola-Lubumbashi Development Road (previously Trans-Caprivi Corridor and until 2004 Trans-Caprivi-Highway) runs from Walvis Bay, through Rundu in north eastern Namibia, along the Caprivi Strip to Katima Mulilo on the Zambezi River, which forms the border between Namibia and Zambia. The Katima Mulilo Bridge spans the river to the Zambian town of Sesheke from where a recently upgraded paved road runs to Livingstone (the M10 Road) joining the main north–south highway to Lusaka, connecting onwards to the Copperbelt. The Trans-Caprivi highway is a section of the Walvis Bay Corridor, a trade route linking land-locked Zambia (and neighbouring countries such as DR Congo, Malawi and Zimbabwe) to the Walvis Bay port on the Atlantic Ocean. An example of the function of the corridor as a trade route is that trucks carry copper ore concentrate from the Dikulushi Mine in South-East DR Congo across Zambia and down the Trans-Caprivi highway to the copper smelter at Tsumeb in Namibia. The refined copper is then exported from Namibian ports. Route As the name suggests, the corridor starts at Walvis Bay (in Namibia), passes through Ndola (in Zambia) and ends at Lubumbashi (in DR Congo). The corridor begins in the coastal town of Walvis Bay as the B2 road, heading northwards to the coastal town of Swakopmund (a distance of 35km), where it turns eastwards. It heads eastwards from Swakopmund, through Karibib, to the town of Okahandja (a distance of 290km), where it reaches a junction with the B1 road. At this junction, the B2 ends and the corridor becomes the B1 northwards. The entire section from Walvis Bay to Okahandja is shared with the Trans-Kalahari Corridor. From Okahandja, it heads northwards as the B1 for 290km, through Otjiwarongo, to the town of Otavi (south-west of Tsumeb), where it reaches a junction with the B8 road. At this junction, the corridor becomes the B8 east-north-east and heads for 345km to the town of Rundu, where it meets the B10 road and becomes the main road through the Caprivi Strip. The section from Okahandja to Otavi is shared with the Tripoli–Cape Town Highway. The corridor resumes being the B8 road and heads eastwards from Rundu for 510km to the border town of Katima Mulilo, where it crosses the national boundary in a northerly direction to enter Zambia. Immediately after crossing the border, it reaches a junction with Zambia's M10 road. The corridor becomes the M10
