KeNHA plans to expand about 17 major roads across Kenya.
KeNHA has earmarked routes in Nairobi, Kiambu and other counties for expansion to improve access and ease congestion.
KeNHA dualling plans target about 17 major roads across Kenya as the government seeks to expand transport networks. The proposed projects include routes serving Nairobi, Kiambu, western Kenya, the Rift Valley and coastal regions.
The Kenya National Highways Authority lists the roads in its National Integration and Accessibility Improvement project portfolio. Its proposals include busy commuter routes, links between counties and roads serving border communities.
The plans also form part of the government’s wider road-building targets over 10 years. These include constructing 28,000 kilometres of tarmac roads and converting 2,500 kilometres of highways into dual carriageways.
KeNHA dualling plans cover Nairobi and Kiambu routes
Among the proposed projects is the 39-kilometre Dagoretti Market–Karen–Bomas–Kiserian–Kona Baridi road. KeNHA expects the expansion to improve connections between Nairobi and several towns in Kajiado.
The route experiences heavy congestion, particularly during morning and evening rush hours. Motorists often spend nearly twice the normal travel time on the road during these periods.
In Kiambu, the authority also plans to expand the 62-kilometre Kiambu–Ngewa–Nembu–Gatundu–Mangu–Thika route. The project would convert the existing two-lane single carriageway into a four-lane dual carriageway.
The Rironi–St Paul’s University–Ndenderu road also appears among the targeted projects. Meanwhile, KeNHA plans to begin dualling the 169-kilometre Makutano–Embu–Meru–Lewa highway in early 2027. That highway connects Kirinyaga, Embu and Meru counties.
Rift Valley, western and coastal roads on the list
In the Rift Valley and Central regions, the portfolio includes the 144-kilometre Nakuru–Nyahururu–Mweiga road. It also lists the 79-kilometre Gwa Kungu–Junction D463–Nanyuki route.
Further west, KeNHA has earmarked the 122-kilometre Mamboleo–Miwani–Chemelil–Muhoroni road, connecting Kisumu, Nandi and Kericho counties. Construction is already underway on some sections.
The authority also plans to expand the Eldoret Airport–Eldoret road and the Town–Chepkoilel University route. These projects aim to improve airport access and ease congestion within Eldoret.
Other proposed improvements cover the Busia–Malaba highway, which links Kenya to Uganda through a busy border crossing. The list also includes Biretwo–Tot and Tot–Marich Pass roads, serving communities in Elgeyo-Marakwet and West Pokot.
Meanwhile, the Garsen–Hola and Hola–Madogo highways feature among the targeted routes in the coastal and northeastern regions.
