Over the years, there has been increasing public investment in transport infrastructure in Kenya both through direct budgetary allocations and private sector partnerships. For instance, in 2018, US$ 2.1 billion (representing almost 10 per cent of the entire 2018/19 annual budget) was allocated to transport infrastructure where over 50 per cent of it was availed for road projects. This was a 100 per cent increase from the previous year.
