The Lot Three segment of the Kopasi River–Lomut–Sigur–Marich Pass road stretches 31.4 km from the Kopasi River to Marich Pass, forming part of a corridor linking Nakuru with Baringo and West Pokot.

Engineer Julius Owino of the Kenya National Highways Authority supervises geometric design, culvert levels and bridge works, while laboratory technician Josephine Naliaka monitors material quality to meet KeNHA specifications.

Three major bridges are included in the works: the 50‑metre Parkino Bridge, the 50‑metre Chepkuikui Bridge, and the 131‑metre Murunji River Bridge.

Overall progress stands at 56.5 per cent, with about 12 km of tarmac already laid and earthworks nearing completion at 90 per cent.

Quality assurance involves testing gravel, monitoring cement stabilisation, and checking moisture and compaction levels to ensure the road can withstand expected traffic volumes.

The project is fully funded by the Government of Kenya through the Development Fund, with no donor contributions, and it sources aggregates and rock locally, creating jobs for nearby residents.

The new corridor will also facilitate the movement of agricultural produce and livestock, helping farmers transport mangoes, goats and cattle to markets such as Nairobi more efficiently.

Improved access is anticipated to aid security forces in reaching remote areas more quickly, enhancing response capabilities during incidents.

Project officials stress that the combination of engineering supervision, rigorous laboratory testing and local material sourcing is shaping a road designed to serve a busy transport corridor for years to come.
