Kenya begins KSh7.5 billion Nithi Bridge replacement on accident-prone highway

Kenya begins KSh7.5 billion Nithi Bridge replacement on accident-prone highway

Built World

An 880-metre span and 2.7 km realignment replace a 1985 crossing linked to hundreds of deaths

Yesterday: Project scope detailed in report

Overview

Updated 1 hour ago

Kenya formally began building a KSh7.5 billion replacement for the Nithi Bridge on October 22, 2026. The 880-metre span rises about 100 metres above the Nithi River in Tharaka Nithi County, replacing a 1985 crossing that has been one of the country's deadliest accident spots for four decades.

Deputy President Kithure Kindiki attended the commencement ceremony and directed contractor China Wu Yi Company Limited to complete the works in under 24 months. The project includes 2.7 kilometres of realigned approach roads with gentler gradients, wider carriageways, and pedestrian walkways.

Why it matters

A highway stretch that has killed hundreds since 1985 is being rebuilt with safer geometry, funded through Kenya's development budget and built by a Chinese contractor.

  1. Expected completion date

    Upcoming Milestone

    Contract details identify August 7, 2029 as the expected completion date, barring delays.

  2. Project scope detailed in report

    Latest Report

    Construction Review details project specs: 880-metre bridge, 2.7 km realignment, completion expected by August 2029.

  3. Formal construction commencement

    Construction

    Deputy President Kindiki attends the commencement ceremony in Maara Constituency, directing the contractor to finish within 24 months.

  4. Valuation complete, early entry allowed

    Process

    Valuation is complete and compensation calculations are underway. An early-entry arrangement lets works proceed while land acquisition finalizes.

  5. Landowner engagement begins

    Process

    KeNHA and the National Land Commission begin engaging affected landowners on valuation and compensation.

  6. KeNHA issues tender

    Procurement

    Kenya National Highways Authority publishes tender documents for the Nithi Bridge realignment project.

  7. Initial bridge design rejected

    Decision

    Deputy President Kindiki rejects a Sh1.7-1.8 billion design as inadequate and directs engineers to design something more ambitious.

  8. Original Nithi Bridge built

    Construction

    The original crossing opens on the Makutano-Embu-Meru (A9) highway, with steep gradients and sharp curves that later prove deadly.

Scenarios

1

Nithi Bridge opens on schedule by August 2029

Likely Resolves by Aug 7, 2029

Discussed by: Kenya National Highways Authority contract disclosures

Construction proceeds without major funding shortfalls or land acquisition disputes. The contractor holds to the contract date of August 7, 2029, opening the bridge and realigned approaches to traffic.

2

Land compensation disputes delay completion

Possible Resolves by Jan 15, 2028

Discussed by: Kenya National Highways Authority

Outstanding compensation claims slow the program. KeNHA has noted that land acquisition is still being finalized even as early-entry works proceed. If disputes reach formal legal challenge, the 2029 completion date slips.

3

Early completion amid accelerated works

Unlikely Resolves by Jan 1, 2029

Discussed by: Deputy President Kithure Kindiki

The government directs the contractor to compress the 24-month construction period below the contract timeline, opening the bridge to traffic before 2029.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

1985 - 2026

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.

Then

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.

Now

The accident record eventually drove the government to fund a KSh7.5 billion replacement, now under construction with completion expected in 2029.

Why this matters now

The 40-year accident history is the direct cause of the current project and explains the higher design standards being applied.

2009-2012

China Wu Yi's Thika Superhighway work (China Wu Yi prior flagship project)

China Wu Yi was among the contractors on Kenya's Thika Superhighway, the country's first toll-quality urban highway connecting Nairobi to Thika. The project demonstrated Chinese contractor capacity on complex Kenyan roadworks.

Then

The highway improved travel between Nairobi and Thika and became a flagship of Chinese infrastructure involvement in Kenya.

Now

China Wu Yi's track record made it a credible bidder for the Nithi Bridge, which it won through competitive procurement.

Why this matters now

China Wu Yi's prior highway experience in Kenya positioned it to handle the engineering demands of the 880-metre Nithi Bridge span.
