Original Nithi Bridge disaster history (1985-2026)
The original bridge opened in 1985 on the Makutano-Embu-Meru highway. Its steep gradients, sharp curves, and poor sight lines made it one of Kenya's deadliest road sections. Buses, lorries, and private vehicles plunged into the Nithi River, with more than 100 lives lost in recent years alone.
Residents spent four decades petitioning successive governments for a replacement, with funding repeatedly unavailable. An initial Sh1.7-1.8 billion design was rejected in 2024.
The accident record eventually drove the government to fund a KSh7.5 billion replacement, now under construction with completion expected in 2029.
The 40-year accident history is the direct cause of the current project and explains the higher design standards being applied.
