  • Realignment and upgrading of several lower-order roads crossing the N1;
  • Partial relocation and upgrading of the Musina Municipal Refuse Site;
  • Construction of the N1 through a 13m deep cutting (max 18m) also crossing a decommissioned undermined area (Harper Copper Mine);
  • Other extraordinary construction activities such as a 3m high noise barrier, relocation of large Baobab trees and 27 new low-cost houses and associated relocation of residents;
  • Preparation of the roadbed or construction of fills followed by selected layers, stabilised subbase layers, crushed stone base layers and asphalt surfacing on all the new surfaced roads.
