This paper analyses the Policy-Making Process (PMP) of transport infrastructure projects in Colombia for the period 2002-10. It aims to identify the main bottlenecks to improve the implementation of public policies in the main phases of the transport infrastructure policy cycle, namely planning, budgeting, execution, and monitoring and evaluation. The main results draw three conclusions. Firstly, there is a need to improve the planning and prioritisation stages of roads construction. Secondly, information problems affect monitoring and evaluation. Finally, the institutional weakness in the transport sector causes co-ordination failures between different transport modes (horizontal level) as well as inadequate separation of responsibilities and management of resources between national and sub-national governments (vertical level). This paper contributes to the research studying the PMP in Latin American economies.
