This project focused on analyzing and redesigning of Simon Mazorodze/Chitungwiza road intersection in Harare, Zimbabwe. Different types of intersections and the cost effective ways of improving roundabout intersections were analyzed using standard procedure. A 96 hour manual traffic survey was conducted at the intersection to determine the current traffic volumes and current capacity of the intersection and then determination of the current intersection performance. Microsoft office, Spreadsheets and AutoCAD were used for design analysis. The results showed that the intersection was not able to handle the high traffic volumes passing through it, hence the justification of upgrading the current intersection. The most appropriate design was chosen, which is designing of a roundabout with bypass slip lanes according to American Standards. The study concluded that the proposed design is able to cope with the traffic for a design life of 20 years. An overpass is recommended to cater for pedestrians.
