Senqu Bridge Infrastructure: Advanced Lightning & Earthing Systems
The Senqu Bridge in Lesotho is a significant infrastructure project that forms part of the second phase of the Lesotho Highlands Water Project (LHWP).
Spanning 825 meters in length and rising approximately 100 meters above a deep valley, it stands as the largest of three major bridges under construction to span the Polihali reservoir. Notably, it is the first extradosed bridge in Lesotho, combining the strength of girder and cable-stayed designs constructafricaperi.co.za. The bridge’s construction commenced in 2018, with the design led by Zutari (formerly Aurecon Lesotho). Standing tall in the Mokhotlong highlands, the Senqu Bridge is exposed to frequent thunderstorms and severe weather.
To protect both the bridge and the people who use it every day, HHK Earthing & Lightning Protection Systems designed and installed a modern earthing and lightning protection system tailored specifically for this structure. Our solution includes advanced structural lightning protection, specialized earthing, and surge protection systems, all installed to meet the strict requirements of SANS Codes of Practice and IEC Standards. These measures not only safeguard the bridge from lightning strikes and electrical surges but also help extend its lifespan and ensure reliable, long-term safety for everyone who depends on this vital route.
Importance of the Senqu Bridge
The Senqu Bridge is not just an engineering marvel but also a critical component of the LHWP, which aims to supply water to South Africa and generate hydroelectric power for Lesotho. The bridge ensures access to Mokhotlong town across the Polihali reservoir, even at full supply, maintaining connectivity to the national road network along the A1, the main road linking Mokhotlong to Maseru, Lesotho’s capital peri.co.za. Upon completion, the Senqu Bridge will play a pivotal role in supporting local economies, facilitating transportation, and contributing to the overall success of the LHWP.
