The target of Colombia's government is to build 7,000 km of roads for the 2016–2020 period and reduce travel times by 30 per cent and transport costs by 20 per cent. A toll road concession programme will comprise 40 projects, and is part of a larger strategic goal to invest nearly $50 bn in transport infrastructure, including: railway systems; making the Magdalena river navigable again; improving port facilities; as well as an expansion of Bogotá's airport.
