The first phase of the Rironi–Mau Summit Road, specifically the Rironi–Naivasha section, is set to open to motorists in August, with completion expected by June. This significant infrastructure development promises to ease traffic and improve connectivity in the region.

• Motorists will pay Sh8 per kilometre on the upgraded dual carriageway, a reduction from the previously proposed Sh10.
• Roads and Transport Cabinet Secretary Davis Chirchir confirmed the August opening to the Senate.
• The 175km Nairobi–Nakuru–Mau Summit project is estimated to cost about Sh90 billion and is scheduled for completion by June 2027.
