Nigeria’s roads and highways form the backbone of the country’s transport network, as these arteries handle 90% of all passenger and freight traffic, according to the NIIMP. As it is the largest segment – contributing N2.4trn ($6.4bn) to GDP in 2020, down from N2.7trn ($7.2bn) the year before – the government is focused on both servicing existing roads – many of which are in poor condition or unpaved – and constructing new ones. Towards this end, the 2021 budget earmarked N168bn ($451.2m) for the construction, rehabilitation and dualisation of roads.
