Theory and practice of high-capacity infrastructure projects are the major focus in the development of countries in the Global South. Aiming at a more fine-grained understanding of such projects, Renard Teipelke studies the Thika Highway Improvement Project (THIP) and its outcomes in the peri-urban Northern Nairobi Metropolitan Region. The THIP is a large transportation infrastructure project that expanded the dual carriageway Thika Road into an eight-lane highway from 2008 until 2012. Based on a strategic mix of methodological approaches, such as interviews with experts in Kenya, literature research and field visits, the ´black box´ THIP is opened up. In the empirical analysis, the project´s idea, its design, and its implementation are studied. It is concluded that the project´s outcomes are ambivalent - partly living up to the expectations of THIP proponents but not resulting in shared benefits for all concerned stakeholders due to flaws in managing the development in this peri-urban transport corridor area, thereby fitting into the Kenyan context of politics and planning.
