Government of Zambia planned to develop KC45 Road Upgrading Project, in Kitwe, Copperbelt, Zambia. Sinohydro Bureau 11 Co Ltd was the construction contractor. The project covered the construction of 45.52 km road, mainly to upgrade the existing 2-lane to two-way 4-lane. The main construction content includes subgrade soil excavation and filling, culverts, bridges, cement stabilized lower bases, broken stone bases and asphalt concrete pavements. As a main part of T3 National Road, the project would ease local transportation pressure and promote Belt and Road Initiative.
