The government plans to expand and toll the Mau Summit–Malaba highway, a move that will require motorists travelling to parts of Western Kenya to pay user fees for their entire journey from Nairobi.

This follows the launch of a pre-feasibility study aimed at upgrading the 243-kilometre highway, converting it into an access-controlled tolled road and expanding its capacity from two lanes to four, according to disclosures by the Public Private Partnership (PPP) Directorate.
