When Davis Chirchir, Cabinet Secretary for Roads and Transport of the Government of Kenya, confirmed that plans are actively progressing for the dualling of the Nairobi-Mombasa Highway, it was more than just a routine update. It was a direct response to mounting pressure from senators and frustrated motorists alike. The announcement came during a tense session before the Senate of Kenya, where Chirchir faced grilling over stalled projects and significant funding gaps.

Here’s the thing: this isn’t just about paving roads. It’s about fixing a logistical bottleneck that has plagued East Africa’s trade corridor for years. The Nairobi-Mombasa route handles roughly 40% of Kenya’s cargo traffic. When it clogs, the economy slows down. Chirchir’s confirmation signals a shift from planning to execution, but the devil is in the details—and the timelines are tight.

The Coastal Corridor: Progress vs. Delays

The focus of the Senate’s scrutiny was largely on the coastal sections of the highway, specifically the segments between Mombasa and Kilifi. These areas have been construction zones for far longer than anyone anticipated. One project, originally slated for a swift 24-month completion, dragged on for 92 months. That’s nearly eight years. And yet, only 54% of the work was done.

Chirchir broke down the current status with specific numbers, trying to restore confidence. He revealed that the Mombasa to Mtwapa section (Lot 1) is currently 42% complete. Meanwhile, the Mtwapa to Kilifi section (Lot 2) is further ahead at 64% completion. But percentages don’t move trucks; finished lanes do. So, what’s the new deadline?

According to the Cabinet Secretary, Lot 2 (Mtwapa to Kilifi) is projected to be completed by March 2026. Lot 1 (Mombasa to Mtwapa) will follow, with a target finish date of November 2026. To improve safety during this transition period, the Ministry also announced that street lighting installation would begin in June 2025. It’s a modest step, but night-time accidents on these stretches are a persistent concern.

Financing the Fix: Money Talks

You can’t build infrastructure without cash, and that’s where the real tension lies. During the same parliamentary appearance, Chirchir addressed the financial hurdles head-on. He disclosed that the government had recently disbursed KSh 88 million to a subcontractor involved in one of the stalled projects. This payment wasn’t just charity; it came with strings attached.

"We recently disbursed Sh88 million and received commitment from the subcontractor to resume works by the end of June 2025," Chirchir stated. This quote, reported by Eastleigh Voice, highlights a delicate balancing act. The government is injecting funds to keep momentum alive, but it’s relying on private contractors to deliver. If they slip up again, the political fallout could be severe.

The broader financing picture remains complex. In a separate social media post referenced by NTV Kenya in June 2026, Chirchir noted that "the government is working on" securing additional financing for major projects. It’s vague, but it suggests that budget constraints are still a active challenge. The question on everyone’s mind is whether the Exchequer can sustain this pace of spending without compromising other sectors.

Inland Highways: Rironi-Mau Summit Update

While all eyes were on the coast, Chirchir also provided updates on inland corridors, particularly the Rironi–Mau Summit Highway. This route is critical for connecting Nairobi to Western Kenya and Uganda. On Saturday, January 10, 2025, the Cabinet Secretary inspected ongoing works there, expressing satisfaction with the pace and quality.

The progress here is quantifiable. At Rironi, the China Road and Bridge Corporation (CRBC) is constructing the first five kilometers. Another five kilometers are being worked on in Gilgil. Further along, the Shandong Construction Company has mobilized at Kariandusi for a 10-kilometer stretch and at Mau Summit for another five kilometers. That’s 25 kilometers of active construction under way.

But the bigger news is what’s coming next. A multi-billion-shilling phase of the Rironi-Mau project is set to commence in August, with completion expected by June 2027. This expansion aims to ease the chronic traffic congestion that turns a two-hour drive into a six-hour ordeal during peak seasons. For truckers and commuters alike, that’s a promise worth watching closely.

What’s Next for Kenya’s Roads?

The implications of these announcements ripple beyond just asphalt. They affect logistics costs, travel times, and regional trade competitiveness. With the Nairobi-Mombasa dualling moving forward and the Rironi-Mau corridor expanding, Kenya is attempting to modernize its backbone infrastructure. However, the history of delays serves as a cautionary tale.

Experts warn that while timelines are optimistic, external factors like weather, supply chain disruptions, and contractor performance can derail even the best-laid plans. The government’s reaffirmation of commitment to completing all ongoing road projects, as noted by K24TVNews, is reassuring. But actions speak louder than words. The next twelve months will be telling. If Lot 2 hits its March 2026 target, it will signal a turnaround in efficiency. If not, the skepticism will deepen.
