The Kenya National Highways Authority (KeNHA) faces opposition to its planned upgrade of the Rironi–Mau Summit Expressway, connecting Nairobi and Nakuru, due to resident objections concerning proposed toll fees. Local stakeholders are demanding alternative routes and facilities before the Public-Private Partnership (PPP) project proceeds.

• Key opposition point: Introduction of toll fees, which residents, including a former Member of County Assembly (MCA), term "double taxation" given existing fuel levies.
• Project scope: Planned expansion of the highway under a PPP arrangement, with motorists expected to pay tolls for 30 years.
• Resident demands: Construction of an alternative route for non-payers, a footbridge for school children, and service lanes for local access.
• Project Status: KeNHA officials confirm design work is ongoing, incorporating public input on elements like traffic flow and toll station placement. Two Chinese companies have submitted proposals.
• Government confirmation: Treasury Cabinet Secretary John Mbadi stated on August 29 that the expansion is set to begin before the end of the year, with discussions for the project, including a joint bid from China Road and Bridge Corporation (CRBC) and the National Social Security Fund (NSSF), in advanced stages.
