Motorists using the planned Rironi–Mau Summit expressway will still have a free alternative route, the government has confirmed.
The Kenya National Highways Authority (KeNHA) said the current A8 road will remain open for motorists who do not wish to pay the Sh8 per kilometre toll on the new 175km expressway.
The project will be built and operated by a consortium led by China Road and Bridge Corporation (CRBC) and the National Social Security Fund (NSSF). The toll road is set to open in 2028.
KeNHA said keeping the existing A8 road toll-free was a key part of the project’s approval, ensuring all road users have a choice.
Officials expect that most paying motorists will shift to the new expressway, reducing congestion on the old road.
The Nairobi–Maai Mahiu–Naivasha (A8 South) road will also be upgraded to dual carriageway but remain toll-free for budget travellers.
The Sh180 billion project will run under a 30-year concession, with the consortium responsible for traffic and revenue risks.
