A collaborative project between UNEP and Penn Design aims to position Diamniadio as Senegal’s new economic and transportation hub, linking Dakar, Thiès, and Mbour amid rapid urban expansion. To address high vacancy rates and underdeveloped street networks, six adaptable street typologies were developed (Street Typologies Toolkit). A key initiative is the Diamniadio Rambla, a vibrant primary road integrating multimodal transit, mixed-use districts, and public spaces. The project also explores a BRT route to solidify Diamniadio’s role as a regional urban and transportation node.
