Kenya Roads Board manager Salome Wamuyele said this has helped enhance economic growth. The roads have been done since the onset of devolution.
According to Wamuyele, Uasin Gishu county alone improved more than 5,000km of roads within the period.
Wamuyele spoke in Eldoret during a visit by the Kenya Roads Board team which is on a countrywide mission to validate its Road Inventory and Condition Survey data collected by the county governments.
The survey is to help in the planning and development of road networks in all the counties.
She said by 2018, the counties had improved more than 161,820km implemented by all counties that benefited from the money allocated for road maintenance under the Road Maintenance Levy Fund (RMLF).
The length of roads done by the counties has since increased hence the new survey being done by the board.
"Our previous survey indicated that Uasin Gishu county government went further to implement roads which are not within the classified regime maintenance by the RMLF but are very critical to the economy and social fabric of any county," Wamuyele said.
Counties, she said, had expanded most roads within their areas to measure more than nine meters wide as required.
Wamuyele expressed the need for the Council of Governors to push for the reinstatement of the fund to remain as a conditional fund for the maintenance of roads in counties.
Uasin Gishu county executive for Roads, Transport and Public Works Joseph Lagat said most subcounties in the region had surpassed targets in the maintenance of roads in the third quarter of the current financial year.
He spoke during a meeting of county staff with the team of officers from Kenya Roads Board.
Lagat said after completion of grading in all wards, more work including installation of culverts, drainage and gravelling, will be done before the onset of rains.
He said his team was committed to ensuring the county gets resilient infrastructure for farmers and residents to use. He also thanked his team for the progress so far in the maintenance of roads.
The roads officials commended Uasin Gishu County for reducing narrow roads drastically by extending their reserves to required standards.
Present during the engagement was acting chief officer Julius Ronoh, Deputy Director Linus Yego and subcounty engineers, surveyors and Inspectors.
