KeNHA gives progress update on Illasit-Njukini-Taveta road

Tarmacking of the 66-kilometre Illasit-Njukini-Taveta (B55) Road is partially completed, opening up a major trade route between Kajiado and Taita Taveta counties.
In an update published on August 5, 2026, the Kenya National Highways Authority (KeNHA) confirmed that key construction phases along the border highway are already done.
KeNHA noted that “Construction of the Illasit–Njukini–Taveta (B55) Road continues to gather momentum, with implementation currently ahead of schedule.” Heavy machinery on site is turning what was long a rough gravel track into a modern, all-weather paved road.
Progress on tarmac laying and drainage works
Giving details on completed works, the roads body stated that “Since works commenced in June 2025, 28 kilometres of the 66-kilometre road have been completed to bituminous standard, while all major drainage structures along the corridor are now complete, marking a significant milestone in the delivery of this strategic transport link.”

The completion of major drainage structures like bridges and box culverts will help prevent washouts that frequently cut off traffic during heavy rains.
KeNHA added that field evaluations showed “implementation is progressing in accordance with the approved quality standards and implementation program, with the project remaining ahead of schedule and on course for completion by December 2027.”
For years, local traders, matatu operators, and farmers moving between Illasit in Kajiado South and Taveta struggled with severe dust during dry periods and deep mud when it rained. The ongoing tarmac laying is bringing immediate relief to road users by cutting vehicle wear and shortening daily journeys.
Boosting cross-border business with Tanzania
Beyond connecting rural towns in Kajiado and Taita Taveta, the B55 corridor serves as a major trade artery along Kenya’s southern border with Tanzania.
Improved transport links in the agricultural region will make it easier for farmers in Rombo and Njukini to move fresh produce, including tomatoes and vegetables, to market centres like Taveta, Oloitokitok, and Nairobi.
Outlining the wider benefits of the highway, KeNHA explained that “Once complete, the Illasit–Njukini–Taveta (B55) Road will strengthen regional connectivity, enhance road safety, facilitate cross-border trade between Kenya and Tanzania, and unlock new socio-economic opportunities for communities along the corridor.”
With construction progressing steadily towards the December 2027 deadline, residents along the border belt are set for better transport and expanded economic opportunities.
