Bridge.From the Luangwa Bridge, the T4 heads east-north-east for 165 kilometres, following the near borderline with Mozambique, through the town of Nyimba, through the Alexander Grey Zulu Toll Plaza, to bypass Petauke to the south (where the D138 provides access to the town centre). From the Petauke turn-off, the T4 heads east-north-east for 87 kilometres, through the town of Sinda, to the town of Katete, where it meets the northern terminus of the T6 Road, which goes southwards to the border with Mozambique. The T6 is the main route used by motorists to access Mozambique from Zambia. From Katete, the T4 heads east-north-east for 80 kilometres, though the Reuben C Kamanga Toll Plaza, to enter the city of Chipata, where it meets the southern terminus of the M12 Road (which goes north to Lundazi and the South Luangwa National Park) before passing through the city centre in a south-easterly direction. Immediately after the Chipata City Centre, the T4 meets the northern terminus of the D128, which goes southwards to Chadiza. The T4 continues east-south-east for 18 kilometres to reach the Mwami Border with Malawi, where it crosses the national boundary and becomes the M12 Road of Malawi, which connects to the city of Lilongwe (Capital of Malawi; 120 kilometres away). The border settlement on the Malawian side is named Mchinji. Branches In addition to its east-west Lusaka-Malawi axis, the Great East Road links north to Lundazi (using the M12 Road from Chipata), north-west to the South Luangwa National Park (using the D104 Road from Chipata), south-east to Mozambique (using the T6 Road from Katete), and, in Lusaka Province, south to the Lower Zambezi National Park and the town of Luangwa at the Luangwa-Zambezi river confluence (using the D145 from the Luangwa Bridge). In the 1960s the Great East road was paved, opening up the Luangwa Valley (and to some extent, Lake Malawi) to tourism. At times the surface has deteriorated considerably. The section between Katete and the Luangwa Bridge was repaired and reconstructed around 2002/3. Strategic significance As well as being strategically vulnerable as described above, the Great East Road is within a few kilometres of Mozambique and a few tens of kilometres of Zimbabwe, where there were wars of independence in the 1960s and 1970s. As a result of Zambia's political support for the anti-apartheid and independence sides in these conflicts, armed incursions cut the road at the Luangwa
