Kirinyaga County Government has announced its adoption of a new and more effective road construction technology that it says will enhance the durability of rural roads in the county.

The county says its ongoing Nyorosha Barabara Mashinani project will see roads constructed using a mixture of quarry dust and hardcore as the main building materials replacing the usual marram.

County Executive Committee Member for Transport Jared Migwi says once the mixture is poured on a well graded road, it will then be pressed with a drum roller to give it a more compact and smooth finish.

“These materials cannot be easily washed away by storm water and roads constructed using this technology are more durable and can last for up to three years without repairs. This will not only give the taxpayers value for their money but will also save us money that can be used to cover more roads,” Migwi said.

Migwi stated that the success of the initiative has been enabled by the working relationship between county executive, the county assembly and the National Irrigation Authority (NIA) among others.

The Nyorosha Mashinani program unveiled by Governor Anne Waiguru is expected to cover more than 500km of roads in Kirinyaga County in the current financial year, with 327km of roads already graded.


Mutithi Ward MCA Jinaro Jamumo says the upgraded road network will enable smoother movement of persons and also empowering farmers to efficiently ferry their produce from their farms to the market.

“People will always look for areas with developed infrastructure to settle in and we are happy that the ongoing roads rehabilitation in our ward is attracting investors and settlers thereby raising the value of our land,” said Jamumo.

In her first term in office, Waiguru procured road construction equipment including five graders, 10 trucks, two excavators, one loader, one backhoe, two roller-compactors and one water bowser for the programme.
