Ivory Coast, 2018-2020
In 2017, the road surface on Ivory Coast’s route 3 was 40 years old and in an advanced state of disrepair. A lack of maintenance, constant excessive truck traffic and failure to comply with speed limits and road signs were the cause of numerous accidents every year on this dual carriageway used by between 300 and 500 trucks per day. Therefore the Ivorian authorities launched in 2017 a programme to renovate some 220 kilometres of route 3, the aim being to improve safety and at the same time reinforce the infrastructure of a strategic artery. In 2018, a consortium made up of Bouygues Travaux Publics (consortium leader), DTP, Colas Afrique and Colas Projects was awarded the contract to renovate a 125-kilometre section of the route between the cities of Bouaké and Kanaholo. A total of 1 million metric tons of rock were mined and crushed to replace the sub-base layer that makes up the structure of the new road and for the wearing course forming the road surface.
