The splitting of the Rironi–Mau Summit Road expansion project has led to complications for the Kenya National Highways Authority (KenNHA) due to differing toll rates and annual price escalation rates proposed by the two chosen consortia.

• The expansion of the critical Rironi–Mau Summit Road will be undertaken by two companies that submitted Privately Initiated Proposals.
• The project was launched by President William Ruto on November 28, 2025.
• The discovery of differing proposed toll tariffs and price escalation rates has created a challenge for the roads agency.
