Sierra Leone’s President, Julius Maada Bio, joined Liberian President Joseph Nyuma Boakai Sr. on Saturday to launch a major 255 kilometre road infrastructure project aimed at strengthening regional connectivity and trade across West Africa.
The project, implemented under a Design, Build, Operate and Transfer concession model, will upgrade key transport corridors in Liberia, forming a critical link within the Mano River Union and the wider Economic Community of West African States region.
The development comprises two main corridors. The Western Corridor includes a planned four lane highway from St. Paul Bridge to Klay, extending to Bo Waterside, with additional connections to Tubmanburg and Robertsport. The Northern Corridor will see the construction of an 86 kilometre two lane road linking Voinjama to Mendikorma.
Speaking at the groundbreaking ceremony, President Bio described the initiative as a historic milestone expected to cut travel time, reduce transport costs, and ease the movement of people and goods across borders. He said the project reflects deepening cooperation between Sierra Leone and Liberia and a shared commitment to economic growth.
President Bio also highlighted the significance of sustained peace in enabling large scale infrastructure investments, noting that both countries have emerged from periods of conflict to pursue development through partnership and resilience. He said the project is a dividend of peace and urged citizens to safeguard stability and support national development efforts.
President Boakai was also commended for advancing infrastructure development as a driver of economic transformation and regional cooperation.
In his role as Chair of the ECOWAS Authority of Heads of State and Government, President Bio emphasized the broader regional impact of the initiative, describing it as a strategic component of West Africa’s economic architecture.
He said the project is not just for Liberia but represents a regional effort that strengthens connectivity, promotes trade, and advances the vision of an integrated West African market.
The 255 kilometre road initiative builds on longstanding efforts by Liberia and its neighbours to rehabilitate critical transport infrastructure damaged during years of civil conflict in the Mano River basin. Poor road networks have historically constrained trade, increased travel times, and limited access to markets, particularly along border corridors linking Liberia with Sierra Leone and Guinea.
The Bo Waterside crossing, one of the busiest land borders between Liberia and Sierra Leone, has long been a bottleneck for regional commerce, with sections of the connecting roads often becoming impassable during the rainy season. Previous upgrades have been incremental, leaving major stretches in need of full reconstruction and modernization.
The project aligns with broader regional integration frameworks under the Economic Community of West African States, which prioritizes transport corridors as a cornerstone for boosting intra African trade. It also complements ongoing efforts within the Mano River Union to strengthen economic cooperation among member states.
Analysts say the adoption of the concession model reflects a growing shift in West Africa toward public private partnerships to finance large scale infrastructure, amid fiscal constraints faced by governments.
Once completed, the corridor is expected to improve cross border mobility, support agricultural supply chains, and facilitate access to ports and urban markets, reinforcing its role as a strategic trade route in the sub region.
