The former T‑junction at Marua in Nyeri County has been converted into a modern interchange, altering traffic patterns and reducing congestion in the area.

Motorists report smoother journeys, particularly for trips from Nyeri to Nairobi, where the previous bottlenecks have been removed.

Residents who have used the route for years note that drivers now need to pay closer attention to the new layout, as familiar turning movements have changed.

Local resident Micky Micky said the interchange has improved traffic flow but warned that first‑time users may find the configuration confusing without clear guidance.

He urged authorities to raise directional signage, noting that many motorists do not look around sufficiently to navigate the new interchange safely.

Pedestrian safety remains a concern, with residents highlighting the lack of footbridges and the difficulty this poses for people with disabilities or visual impairments.

Road worker Emmanuel John Ngale, who has been on the project for about three years, advised drivers to observe traffic signs closely as they become familiar with the upgraded highway.

The Marua interchange forms part of the wider Kenol‑Sagana‑Marua corridor upgrade, which aims to improve connectivity across the Mount Kenya region.

Commentators note that, as traffic volumes increase on major highways, properly designed crossing points, accessible pedestrian facilities and clear road markings can help communities interact safely with upgraded roads.
