| Abstract: | Expressway of Kampala to Entebbe（KE） is the first expressway in Uganda, Busega interchange of KE project that connecting the north ring is an important part in this project. Optimum scheme of dumbbell-shaped interchange is determined after analyzing influence factors of technical indicators, construction difficulty, land acquisition, employer＇s requirements. Horizontal alignment design, cross section and vertical section design are focused on in this paper. The general layout of Busega interchange is reasonable and economical and it is valuable for the similar proiects in East African rezion. |
