Project General Description

This Infrastructure Sector Support Project - Phase I (PASIG-I) is an investment operation. This first phase consists mainly of: (a) construction and asphalting of the Ndendé-Doussala road section (49 km) and the border bridge over the Ngongo River; (b) construction and asphalting of 21,280 km of roads in Libreville, including related developments (sanitation, street lighting, beautification); and (c) detailed sector and technical studies to feed a substantial pipeline of transformative projects in the road subsector. The project is part of the Trans-Gabonese corridor development scheme expected to link Libreville to Mayumba in the South, and crosses timber, mining, metallurgy, agro-industry, fishing, livestock and ecotourism hubs, among others. However, developing the economic potential in the project impact area, which is limited to Ngounié Province, is currently undermined by the poor state of transport infrastructure. The main expected outcomes include improved logistics chain service on this road axis as well as mobility and living conditions for people in the PIA. The project will reduce travel distances by increasing the access rate to basic services for residents of the PIA. Covering the period 2020-2023, PASIG I is structured around five components include, apart from road works on the Ndendé - Doussala section and urban roads, ancillary developments (rural roads and social action) and other measures aimed at better protecting the road infrastructure and facilitating transportation.

Project Objectives

PASIG I overall objective is to help open up Ngounié Province and reduce transport time and costs on the Libreville - Brazzaville corridor. Specifically, the project aims to: (i) improve the efficiency of the transport logistics chain; (ii) reduce the cost of transporting products on the Libreville/Brazzaville link; (iii) improve travel conditions in Libreville and (iv) contribute to improving access to socio-economic infrastructure for people in the project impact area.


The main project beneficiaries are agricultural workers, particularly women, who are experiencing difficulties in sourcing inputs and selling their products due to poor conditions along the corridor. Other project beneficiaries are industrialists, transporters and shippers whose operating and logistics costs will be substantially reduced with the development of the axis and the opening of rural roads. The project will also benefit the urban residents of Libreville.
