Contractors started the first layer of tarmac on the Rironi‑Naivasha segment of the Rironi‑Mau Summit highway, moving the project from earthworks to paving.

Kenya National Highways Authority Director General Luka Kimeli inspected the work on Tuesday, watching the blacktop being applied near the Ngarariga Interchange.

Roads Cabinet Secretary Davis Chirchir said the dual‑carriageway Rironi‑Naivasha section is expected to be completed and opened to traffic by 30 October, even as work continues on adjacent stretches.

Chirchir explained that the Ministry will first open the upper side of the A8 corridor before moving to the A8 South segment that links Rironi, Mai Mahiu and Naivasha.

The phased opening model is intended to ease chronic congestion on the Nairobi‑Nakuru route, especially around Naivasha, Gilgil and the Rift Valley escarpment.

The overall upgrade will dual the A8 and A8 South corridors, expanding capacity for commercial traffic between Nairobi, the Rift Valley and western Kenya.

While the Rironi‑Naivasha stretch remains on track for its October opening, the Ministry targets full completion of the entire Rironi‑Mau Summit corridor by June 2027.
