Project description
Project scope
The project road was upgraded from a gravel road Class C to Class II bitumen standard with a double bitumen surface treated carriageway of 6.0m width throughout and surfaced shoulders on each side, of 0.5/1.0m in the mountainous terrain and 1.5m in the flat terrain. The original detailed engineering design for the road upgrading works done in 1996 was checked and updated by M/s TYPSA of Spain in association with M/s Prome in 2007 and 2008. H.P Gauff Ingenieure GmbH & Co; KG-JBG in association with Gauff Consultants (U) Ltd were contracted in 2009 to conduct a thorough design review and construction supervision of the civil works.
The upgrading works followed the updated design in which the route via the current section between ltojo - Sempaya was deviated so as to avoid the existing safety hazardous sharp bends and steep gradients along this section. The deviation follows a route designated as alternative 2A starting at ltojo traversing through Kibuuku, Rwamabale, Burondo via the road to Rwebisengo and re-joining the main road at Sempaya. The alternative route is 10.9 km longer than the original hazardous road.
The road traverses land with a high potential for agricultural production of cocoa, palm oil and natural resources such as oil reserves which, recent studies indicate economically viable to exploit in the region.
