Abstract
The project focussed on the design of a link road to connect the Beitbridge-Chirundu Highway to Harare Drive and Kirkman Road in Harare, Zimbabwe. The proposed link road is approximately 17 km long. The link road will alleviate traffic flowing into Harare by linking the missing portion of Harare drive a ring road to a major highway. A manual traffic count was carried out to determine the percentage of heavy vehicles in transit on the highway. The results were compared to historic traffic counts. The analysis was carried out using QGIS and AchiCAD softwares, Microsoft excel and AutoCAD. The geometric design of the link road and intersection was carried out based on guidelines for Southern Africa roads. The link road and grade separated intersection with a design life of 20 years was designed. It is recommended that traffic flow be diverted and extra caution be taken during the construction.
