SA and Lesotho strengthen ties with Senqu Bridge launch

South Africa and Lesotho have reached a major milestone in their long-running partnership with the launch of the Senqu Bridge, a key structure in Phase II of the Lesotho Highlands Water Project (LHWP). This development highlights the continued cooperation between the two neighbouring countries in addressing water security, infrastructure, and regional development.

The Senqu Bridge is located in the remote Mokhotlong District of Lesotho and is scheduled to be officially opened on 22 April 2026. The launch is expected to be attended by high-level leaders from both nations, underlining the political and economic importance of the project. The event reflects not only progress in construction but also the strength of diplomatic and developmental ties between South Africa and Lesotho.

With a construction cost of approximately R2.4 billion, the Senqu Bridge is the largest of three major bridges being built as part of Phase II. It spans about 825 metres across the Senqu River valley and rises roughly 90 metres above the ground, making it one of the most impressive engineering structures in the region. Its scale and design demonstrate advanced engineering capabilities and a significant investment in long-term infrastructure.

The bridge is being constructed to address a critical future challenge. Once the Polihali Dam—another central component of Phase II—is completed, water levels in the area will rise and submerge existing roads and crossings. Without alternative routes, communities in the region, particularly around Mokhotlong, would face isolation. The Senqu Bridge ensures continued connectivity, allowing people, goods, and services to move freely despite the changing landscape.

In addition to improving transport access, the bridge supports broader economic activity in the region. Reliable road infrastructure is essential for local development, enabling trade, access to services, and job opportunities. During its construction, the project has also contributed to employment and skills development for local workers.

The Senqu Bridge forms part of the wider Lesotho Highlands Water Project, a binational initiative established in 1986. The project is designed to transfer water from Lesotho’s highlands to South Africa, particularly to supply the industrial and densely populated Gauteng region. In return, Lesotho benefits through royalties, infrastructure development, and increased hydropower generation capacity.

Phase II of the LHWP includes the construction of the Polihali Dam and associated infrastructure such as tunnels, roads, and bridges. Once completed, this phase is expected to significantly increase the volume of water delivered to South Africa, improving water security in one of the country’s most economically important regions. At the same time, Lesotho stands to gain from enhanced energy production and further economic growth.

Overall, the launch of the Senqu Bridge represents more than just the completion of a physical structure. It symbolises progress in regional cooperation, a shared commitment to addressing future water needs, and the long-term benefits of strategic infrastructure investment. The project continues to play a vital role in strengthening the relationship between South Africa and Lesotho while supporting sustainable development for both nations.
