Liberia Roads Assessed for Either Complete Upgrade or Rehabbed on Emergency Basis

The project entailed detailed site assessments of 26 links of roadway and over 200 bridges.  Link prioritization was performed using the HDM-III and HDM-IV models and other transportation analysis software.  Traffic studies were performed and these included traffic counts, O-D surveys, and traffic projections based on economic development for the country and costs of fuel and other factors.  A complete pre-feasibility and feasibility study was performed and emergency road links were identified, catalogued and analyzed in terms of IRR and NPV and other economic parameters.

Land acquisition and resettlement were important components of the study and these required an economic and physical inventory of the prioritized road links and identification of land ownership and Right-of Way infringement.  Once the road links were prioritized, the bridges were examined and the roadways were evaluated based on needs and emergency repairs and economic and financial guidelines provided by the Bank.  Roughness tests were conducted as well as deflection test using the Benkelman Beam. All surveying was performed using the total station.

A complete economic analysis was performed to justify the upgrade, repairs, and new construction for the final 150 kilometers of two-lane asphalt roadway that link Monrovia to Buchanan and Monrovia to the Guinea border.
