The Kenya National Highways Authority (KeNHA) is set to undertake a multi-million road upgrade project on the Kiambu-Mang’u-Thika super highway dual carriage. Not only does the project cover the titled Kiambu–Ngewa–Kibichoi Road(22km long) but also extends further on Kibichoi Road to the entire 62km long road. The road then ends at the junction B30/A2 on the Thika Road.

An environmental impact assessment (EIA) report noted that “Sections of the road will be constructed to dual carriageway, single carriageway while further work will be an evaluation of the road capacity and pavement evaluation,” 

Reports by KeNHA have it that the project will commence at Junction B32/B30 on Kiambu Road, just facing the Kiambu Institute of Science and Technology then cut through Kirigiti, Arabia, Ngewa, Kibichoi, Nembu, Ichaweri, Gatundu, Kang’oo, Mang’u and terminate at Thika road junction. 

The road upgrade will then be split into six phases. A 12km dual carriage will be initiated from Kiambu Road to Ngewa and connected to 10km single-carriageway phase to Kibicho under the rural road standards. A 22km extension from Kibicho to Kang’oo through Ichaweri and Gatundu will have a road and pavement appraisal, currently under construction.

From Kang’oo to Mang’u, a 4km stretch, there shall be a single carriageway as per the rural roads standards leaving a 14km phase that will connect Mang’u junction to Thika Road. This stretch will be designed to have a dual carriageway.

The main aim of the Kiambu-Mang’u-Thika road upgrade is to solve the traffic jam that is currently being experienced due to the increasing number of homes in the area, the new home to people mainly working in the neighbouring towns.

This project is expected to be completed by June 2022, opening the gateway for further growth of real estate in Kiambu County.
