On Monday, senior government officials led by Deputy President Kithure Kindiki conducted an inspection tour of major road construction works in Kiambu County, marking a key milestone in one of Kenya’s largest ongoing infrastructure upgrades along the Northern transport corridor.
The visit covered extensive sections of earthworks, drainage systems, and pavement preparation along the 175-kilometre highway project that was officially launched by President William Ruto in November 2025.
The ambitious expansion project is designed to transform the heavily congested A8 highway into a modern four-to-six lane toll road, significantly improving traffic flow between Nairobi and surrounding economic zones.
According to officials on site, the upgrade also includes the construction of a parallel 58-kilometre auxiliary route intended to ease traffic diversion during peak construction phases and provide long-term redundancy for the corridor.
The project, estimated to cost between KSh 170 billion and KSh 200 billion, is being financed through a public-private partnership model involving both the Kenyan government and international contractors, including firms from China with experience in large-scale road infrastructure.
During the inspection, Kindiki moved through multiple construction sections, engaging engineers and project managers on progress timelines, safety standards, and technical challenges.
He observed ongoing earth compaction works, drainage channel alignment, and base layer preparation, all of which are critical stages before final asphalt paving begins.
Officials accompanying the Deputy President noted that the project has reached an advanced phase of groundwork, with several stretches already showing visible transformation from the previous narrow and congested highway into a widened transport artery.
Kindiki, while addressing engineers and local administrators, stated that the works had “gathered momentum,” signaling increased confidence in the pace of implementation.
The broader objective of the highway expansion is to decongest one of Kenya’s busiest transport routes, which connects Nairobi to key industrial and agricultural regions in the central and northern parts of the country.
The A8 corridor has long been notorious for traffic bottlenecks, frequent accidents, and delays that affect both commuters and freight movement.
Authorities believe the upgrade will significantly reduce travel times and improve road safety once completed.
In addition to easing congestion, the project is expected to have a major economic impact along the route.
Construction activities have already created employment opportunities for local residents in Kiambu County and surrounding areas, with jobs ranging from skilled engineering roles to casual labor positions in material transport and site support services.
Local businesses have also reported increased activity due to the influx of workers and contractors.
The government has emphasized that the toll-based financing model is central to the project’s sustainability.
Under the public-private partnership framework, private investors are expected to recover costs through toll fees once the highway becomes operational. Officials argue that this approach reduces pressure on public finances while ensuring long-term maintenance and efficiency.
However, the project has also drawn public interest regarding affordability and accessibility once tolling begins.
While supporters argue that improved infrastructure will justify user fees, some stakeholders have called for careful regulation to ensure that transport costs do not become prohibitive for ordinary commuters and small-scale traders who rely heavily on the route.
Engineers on site indicated that full completion is targeted for late 2027, provided construction timelines remain on track and funding flows continue uninterrupted.
They noted that weather conditions, material supply chains, and land acquisition processes remain among the key factors that could influence the schedule.
Despite these challenges, optimism remains high among project officials, who view the highway expansion as a transformative development for Kenya’s transport sector.
Once completed, the upgraded corridor is expected to significantly improve connectivity between Nairobi and the wider Northern Corridor trade network, which serves as a critical gateway for regional commerce linking Kenya to neighboring countries.
As the inspection concluded, Kindiki reiterated the government’s commitment to delivering modern infrastructure that supports economic growth and regional integration.
The project, he noted, represents not just a road upgrade but a long-term investment in efficiency, safety, and national development.
For now, construction continues across multiple sections, with heavy machinery, engineers, and workers steadily reshaping one of Kenya’s most important transport arteries—turning long-standing congestion points into a structured, high-capacity highway designed for the future.
