KeRRA: Why the new Ngong-Suswa road is in a deplorable state

KeRRA argues that the maintenance will be undertaken in phases to address existing pavement distress caused by overloading and to improve road safety.

Likewise, the authority says the road was constructed with axle load limits of up to 10 tonnes per axle, but has since been subjected to traffic carrying up to 50 tonnes, accelerating its deterioration.

"This is evident, especially on the right side of the road as you go to Suswa," the Authority said in a statement.

The Ngong-Suswa road has been open to traffic for the last 8 years, and the last section was only completed in December 2025. 

KeRRA has said that the installed Ngong-Suswa-Ewaso- Kedong virtual weighbridge will be used to detect overloaded vehicles and enforce axle load limit compliance as per the Traffic Act. 

It also reported that offenders have been arrested and charged. 

Meanwhile, the Authority is continuously improving the road to meet high traffic usage, as road users have been advised to adhere to the stipulated load limits.
