Chinese Contractors Gain an Edge as Rironi-Mau Summit Road Races Ahead of Nairobi-Mombasa Highway

Kenya’s ambitious road expansion programme is taking different paths, with the Rironi-Mau Summit Highway advancing into construction while the proposed Nairobi-Mombasa road dualling remains at the planning and procurement stage.

The difference has sparked debate over the role of Chinese contractors in Kenya’s infrastructure development and why some major road projects move faster than others.

According to a report by People Daily published on Saturday, October 31, the progress of the two projects is largely explained by their financing arrangements, procurement processes and construction plans rather than the nationality of the contractors alone.

The 233-kilometre Rironi-Mau Summit Highway was launched by President William Ruto in November 2025.

The project is being implemented through public-private partnerships involving China Road and Bridge Corporation, the National Social Security Fund and Shandong Hi-Speed Road and Bridge International.

The highway has been divided into two sections to make financing and implementation more manageable.

The approach enabled the government to secure separate concession arrangements and commence construction.

The project is expected to ease traffic congestion, improve road safety and facilitate the movement of goods between Nairobi, western Kenya and neighbouring countries.

However, the construction timeline has faced challenges.

Transport Cabinet Secretary Davis Chirchir announced on October 30 that the opening of the Rironi-Naivasha section had been pushed from October to December 2026 after contractors failed to meet the earlier deadline.

Meanwhile, the Nairobi-Mombasa highway expansion has encountered significant setbacks.

An earlier proposal by US-based Everstrong Capital to construct a new expressway was rejected by the government’s Public-Private Partnership Committee in July 2025 over concerns about financing, technical capacity and commercial viability.

The government subsequently changed direction, opting to upgrade the existing 461-kilometre Nairobi-Mombasa highway into a minimum four-lane, access-controlled toll road.

The revised project requires further technical and financial assessments before a new investor can be selected.

Consequently, the Nairobi-Mombasa project has yet to reach the construction stage achieved by Rironi-Mau Summit.

The comparison highlights the importance of securing viable financing, completing procurement procedures and establishing workable project designs before construction begins.

Although Chinese firms have secured major contracts on the Rironi-Mau Summit corridor, the Nairobi-Mombasa experience demonstrates that successful infrastructure development ultimately depends on sound planning, financing and effective project implementation.
