VIADUCT BEING CONSTRUCTED ALONG KENYATTA AVENUE, NAIROBI CITY
A viaduct is a long, elevated structure built to carry a road or railway over obstacles such as valleys, rivers, other roads, or dense urban areas.
It typically consists of a series of tall supports or pillars that hold up a continuous deck, allowing vehicles or trains to pass smoothly above whatever lies beneath.
Unlike a typical bridge that crosses a single point like a river, a viaduct often stretches over a wide area and is designed to maintain a gentle slope, making it ideal for steady traffic flow.
The main purpose of a viaduct is to reduce congestion and improve connectivity by separating traffic levels.
It allows vehicles to move uninterrupted over busy junctions or ground-level infrastructure.
In essence, it is like a flyover but on a much larger scale, helping to ease movement in crowded or complicated transport zones.
In the case of the Kenyatta Avenue project in Nairobi, the viaduct being constructed will link Valley Road directly to Kenyatta Avenue, enabling vehicles to pass over the usual bottlenecks and junctions.
This is expected to significantly reduce gridlock in the area and create a more efficient traffic flow through the city.
The project, which was initially scheduled for completion in 2023, stalled due to funding challenges. KURA plans to complete the project by October 2025.
The project will feature a dual carriageway stretching approximately 7 kilometres, complete with adjoining road networks and two overpasses.
KURA has also revealed it has incorporated cycle lanes and walkways in the project.
