The Kenya National Highways Authority (KeNHA) has provided an explanation for the prolonged delays in completing a critical section of Mombasa Road, which has caused significant traffic congestion for motorists using the highway.
KeNHA attributed the delays to the adoption of the Hand Packed Stone (HPS) technology for constructing the road’s sub-base. This method, while labor-intensive, is expected to enhance the road’s structural integrity and provide long-term durability. “This labour-intensive method enhances the road’s structural integrity, ensuring taxpayers get value for money,” the agency stated.
Addressing Drainage Challenges
In addition to structural improvements, the ongoing works aim to tackle drainage challenges associated with the high percolation of water in the area. KeNHA revealed that the wet ground conditions necessitated the introduction of a rockfill base to stabilize the foundation.
To further strengthen the road, the surface will be reinforced with a layer of “dense bitumen macadam” and asphalt concrete. This reinforcement is expected to enhance the road’s resilience to accommodate the increasing traffic loads in the future.
Motorists Bear the Brunt
Motorists along Mombasa Road have endured weeks of heavy traffic congestion due to the delays. The traffic jams have prompted some drivers to seek alternative routes, such as the Nairobi ExpressWay. However, the costs associated with using the ExpressWay have made it a less favorable option for many.
Despite the inconveniences, KeNHA has not provided a specific timeline for the completion of the ongoing works.
Rehabilitation Timeline
The rehabilitation of Mombasa Road commenced on April 26, 2023, with a projected completion date of April 25, 2025. The rehabilitation works are part of routine maintenance aimed at repairing damaged sections of the highway following the completion of the Nairobi ExpressWay.
The then Roads and Transport Cabinet Secretary Kipchumba Murkomen disclosed the timeline while addressing Parliament.
Two major contracts have been awarded for the rehabilitation project:
- The Nairobi Southern Bypass Interchange (Ole Sereni to Athi River Interchange) stretch has been contracted to M/S Wolf Paving Works Kenya Limited at a cost of KSh 1.86 billion.
- The James Gichuru Road Junction to Nairobi Southern Bypass Interchange stretch will be handled by M/S Shovels N Trowels Limited for KSh 1.19 billion.
Scope of Works
The scope of the rehabilitation works includes:
- Recarpeting of the road.
- Excavation to address foundational weaknesses.
- Installation of drainage systems to manage water flow.
- Road markings to enhance traffic safety.
Historical Context
The delays in the rehabilitation project come in the wake of the construction of the Nairobi ExpressWay, which was completed in 2022. The 27-kilometer ExpressWay, constructed by the China Road and Bridge Corporation (CRBC) at a cost of KSh 72.8 billion, has since become an alternative route for many motorists seeking to avoid congestion on Mombasa Road.
Challenges and Prospects
While the rehabilitation project aims to provide long-term solutions to the structural and drainage challenges of Mombasa Road, the delays have frustrated many motorists. KeNHA’s adoption of the HPS technology underscores the agency’s commitment to quality, but the lack of clear timelines has raised concerns about accountability and planning.
As the project progresses, KeNHA will need to provide regular updates to ease public concerns and ensure that the road serves its purpose effectively upon completion. For now, motorists are left to navigate the challenges of heavy traffic and alternative routes as the crucial rehabilitation works continue.
