NAIROBI, June 29, 2026 — President William Ruto has announced that the government will dual the key Muthaiga–Kiambu Road in a Ksh30 billion (approximately US$221 million) infrastructure push to address transport challenges in the metropolitan area.

According to the Head of State, the major project aims to “improve access to the Kiambu corridor and expand Nairobi’s investment.” The 23.5-kilometre route, which connects Nairobi to Kiambu, has experienced severe traffic congestion due to rapid urban expansion.

By expanding the existing single carriageway B32 road into a four-lane dual carriageway, complete with two-lane service roads on both sides, pedestrian walkways, and six footbridges in high-traffic areas including Ridgeways, Thindigua, and Kiambu Town, the state intends to streamline traffic flow and reduce travel times. The scope also includes new bridges and overpasses at key points such as Muthaiga Golf Club Spur, Coffee Garden, Tala Road, and Kirigiti Junction, alongside full interchanges at Kamiti Road, Banana Road, and the Northern Bypass. Two bypasses in Kiambu Town will divert heavy vehicles away from the central market. The redesigned road will cover three sections: Muthaiga to Kirigiti Junction, Kirigiti through Kiambu Town to the Governor’s Office, and the Governor’s Office to Ndumberi near Sasini Estate.

This is expected to lower the cost of doing business for enterprises operating along the busy corridor. The project is also projected to spur real estate and commercial growth, as improved accessibility will make surrounding areas more attractive to local and international investors.

The expansion is expected to create jobs during the construction phase and foster long-term economic resilience in both Nairobi and Kiambu counties. Robust infrastructure remains key to unlocking the full economic potential of the Nairobi metropolitan area. The executing agency is the Kenya Urban Roads Authority (KURA) , with Chinese firm Stecol Corporation contracted for the works under a 36-month construction period.

Notably, while the President announced a Ksh30 billion budget, financing for the project is drawn from a Ksh38.7 billion loan from China’s EXIM Bank, reflecting the strategic importance of decongesting the northern entry point to the capital.

As Nairobi continues to grow as a regional economic hub, upgrading critical entry and exit points remains a priority for the administration. This dualling marks a significant step toward an integrated transport system and forms part of a broader infrastructure push announced on June 29—which also included the Ksh3.8 billion Ngong Road–Naivasha Road flyover, the Ksh44.9 billion Intelligent Transport System rolled out in three phases, the Ksh3 billion Upper Hill–Kenyatta Avenue viaduct (now 60% complete), the Ksh1.6 billion State House Road upgrade, and the Ksh3.9 billion access roads to Talanta Sports City Stadium.
