Project General Description

The Dinguiraye-Nioro-Keur Ayib road, which is about 40 km long, is a section of National Highway No. 4 (NH4) on the “trans-Gambian" corridor and constitutes an economic and strategic link between the North and South of the Gambia and Senegal on the Dakar-Lagos Trans-African highway. Given its strategic location within the groundnut basin, the NH4 is vital for the collection and transportation of agricultural produce to major commercial centres. The project comprises: (A) the rehabilitation of the road from Dinguiraye to Keur-Ayib and 6 km of urban roads in Nioro, including environmental protection measures; (B) related works including the rehabilitation of 49 km of feeder roads and basic socioeconomic infrastructure; (C) final design for the rehabilitation of the Tambacounda-Navel section (247 km) of the NH7 and a study on an urban mobility strategy for Kaolack town; and (D) support for project management and monitoring. The project activities will be carried out from June 2014 to June 2018. The project’s total cost, exclusive of taxes and customs duties (ETCD), is estimated at UA 30.2 million.

Project Objectives

The project’s sector goal is to contribute towards boosting sub-regional trade and opening up rural areas. The project’s specific objective is to facilitate the movement of goods and people along the DinguirayeNioro–Keur Ayib road so as to increase trade with the rest of the country and/or sub-region and improve the population’s accessibility to basic services.


The populations of the Kaolack region, estimated at 795,906 inhabitants, which represents 6.2% of the population of Senegal, are the main beneficiaries.
