Kwa Jomvu–Mariakani highway upgrade to be completed by January 2026, KeNHA says

KeNHA, which is overseeing the works, said the road starts just after the Kwa Jomvu Interchange and follows the alignment of the existing A8 highway through Miritini, Mazeras and Mariakani and ends shortly after the Mariakani Weighbridge.
The Kenya National Highways Authority (KeNHA) now says it will complete the 30.4 kilometre Kwa Jomvu–Mariakani highway by January 19, 2026.
According to the Authority, the project, which began on July 17, 2023, is currently 24.85 per cent complete and will expand the current single carriageway into a four-lane dual carriageway. The project is being implemented at Sh10.4 billion.

KeNHA, which is overseeing the works, said the road starts just after the Kwa Jomvu Interchange and follows the alignment of the existing A8 highway through Miritini, Mazeras and Mariakani and ends shortly after the Mariakani Weighbridge.
The scope of the project includes capacity enhancement of the existing road, provision of climbing lanes and service roads at various locations, improvement of grade-separated intersections, construction of non-motorised traffic facilities, bus stops and enhanced urban drainage systems.
The government secured funding for the project through the European Investment Bank, the German Development Bank and the European Union.
So far, KeNHA says an 18.5-kilometre section of the highway has been handed over to the contractor after the compensation of Project Affected Persons (PAPs) within that stretch. Of this, the contractor has completed 16.6 kilometres on the left-hand side and 8.2 kilometres on the right-hand side.
“The remaining 11.9km will be worked on after compensation of the Project Affected Persons along that section,” Kenha Deputy Director for Corporate Communication Samuel Kumba has said.
He confirmed that the contractor has remained on site since the project’s commencement and is executing the works as scheduled.
“KeNHA is closely working with the relevant government agencies to resolve the challenges facing the project to avert any delays, especially land compensation,” he added.
