Motorists using the Rironi–Mau Summit Highway will pay Ksh1,400 for the full journey in the 175-kilometre stretch of the toll road. 

According to the Principal Secretary of Interior and National Administration, Raymond Omollo, the road will be tolled at Ksh8 per kilometre for small cars, with trucks and buses evaluated a little differently. 

“By the end of 2027, the Nairobi–Nakuru journey will no longer feel like a test of patience but a sign of real progress – a Kenya moving forward for its people,” PS Omollo said.

While providing more details on the highly anticipated road, PS Omollo insisted, just like the Nairobi Expressway, there will be alternative routes provided along the way.

“When the road is complete, it will be tolled at Ksh8 per kilometre, about Ksh1,400 for the full journey. But Kenyans will also have improved alternative routes, because choice matters. Safety matters. Fairness matters,” states Omollo.

According to the update, the new highway will have a four-lane dual road from Rironi to Naivasha. It will then increase to six lanes from Naivasha to Nakuru.

“From Naivasha to Nakuru, where the trucks and buses pack the road from morning to night, it expands to six lanes to keep everyone moving,” PS Omollo asserted. 

In Nauru City, the Ksh200 billion road project will be elevated to avoid congestion in the city.

“Beyond Nakuru, the road becomes a spacious four-lane highway all the way to Mau Summit, opening up travel to Western Kenya like never before,” PS Omollo stated.

Adding, “It means shorter trips for traders, faster access to hospitals, more reliable supply chains for farmers, and smoother trips for students travelling to and from school.”

The road, expected to be complete by 2027, is aimed at easing the flow of goods from Mombasa to Western Kenya and the trade routes into Uganda, Rwanda, and the DRC. 

This will improve connections and lower costs and time on the road from the Port of Mombasa to the Malaba and Busia border stops amid rising competition from Tanzania.

To completely eradicate traffic, the government is also widening the Westlands-Rironi road to six lanes.
