MARIAKANI, Kenya — The Kenya National Highways Authority (KeNHA) has emphasized the scale of enforcement at the Mariakani weighbridge, revealing that approximately 15,000 trucks are weighed every week along the busy Mombasa–Nairobi highway.
According to Victor Kithome, the External auditor for the Mariakani, Dongo Kundu and Mtwapa cluster the weighbridge remains a key checkpoint for monitoring heavy commercial vehicles and enforcing compliance with legally prescribed weight limits.

Traffic and Infrastructure Protection
KeNHA noted that overloading by trucks causes accelerated wear on roads and bridges, leading to higher maintenance costs and safety risks.
The authority says consistent enforcement at Mariakani is intended to curb overloading, protect critical road infrastructure, and enhance safety for motorists using the corridor.
The Mombasa–Nairobi highway is one of Kenya’s most important transport routes, handling freight from the Port of Mombasa to inland destinations across the country and the region.
Wider Improvements Underway
The weighbridge enforcement forms part of broader efforts by KeNHA to improve traffic management and infrastructure along the corridor.
Authorities say continued monitoring, combined with ongoing road improvements, is necessary to safeguard public investment and ensure smoother movement of goods and vehicles through Mariakani and beyond.
