Our Projects
Commonly known as the Machakos Turnoff Expansion, this road was a flagship project that fundamentally changed the logistics of the Nairobi–Mombasa highway.
Project Description
This engineering feat entailed the dualling of a 20-kilometer section of the A8 highway. To handle the immense axle loads of transit cargo, the roadbed utilized a 175mm cement-bound Graded Crushed Stone (GCS) base topped with heavy-duty bituminous layers. The project featured three massive grade-separated interchanges at Green Park, Daystar, and Mua Hills, which eliminated major traffic bottlenecks. Additionally, the Athi and Stony Athi river bridges were elevated to mitigate the risk of seasonal flooding.
Key Stats
1. Total Length: 20 km of dual carriageway.
2. Structures: 2 River Bridges, 3 Interchanges, 3 Footbridges.
3. Funding Ratio: 60% World Bank / 40% Govt of Kenya
4. Status: Handed over September 2025.
Project Facts
- The project was completed and officially handed over in September 2025.
- Construction was co-funded by the World Bank and the Government of Kenya.
- The design replaced dangerous roundabouts with flyovers to accommodate heavy trailers.
