Objectives & Context
Maryland County in southeastern Liberia is one of the country's most geographically isolated regions, historically accessible only by air or sea for much of the year. The Fish Town–Harper road corridor is the only overland route connecting Maryland to the national road network, and Phase II of the rehabilitation programme covered a 60 km section through challenging coastal forest terrain with numerous creek and river crossings requiring permanent bridge structures. Procurement of an internationally competitive contractor to work in such a remote location, combined with the logistical complexity of mobilising construction materials and equipment, required particularly careful planning and supervision.
Our Approach & Solution
TSC Global delivered engineering design and construction supervision for Phase II, building on lessons learned from Phase I. Design prioritised permanent bridge structures over temporary crossings to break the cycle of annual damage and repair, with reinforced concrete structures designed to the 1:100 year flood standard. A logistics plan was developed jointly with the contractor to pre-position critical materials ahead of the rainy season. Supervision included embedded laboratory technicians and bridge inspection specialists, with weekly reporting to the Ministry and AfDB on progress, quality, and safeguard compliance.
Results & Impact
Phase II delivered 60 km of rehabilitated road with 8 permanent bridge structures, significantly reducing the risk of seasonal isolation of Maryland County. Combined with Phase I, the programme restored a continuous overland connection from Harper to the national network, reducing travel times from over 12 hours in dry season to under 5 hours year-round, and opening Maryland County to increased agricultural investment and commercial activity.
