Kenya's KeNHA to close Thika-bound service lanes at Kihunguro from 15 November to 20 December

The Kenya National Highways Authority (KeNHA) will close the Thika-bound service lanes at Kihunguro on the Thika Superhighway from 15 November to 20 December 2026, according to the Kenyan daily The Star and the news site Kenyans.co.ke, which reported the notice on 9 November 2026.

Traffic heading from Nairobi to Thika will be diverted through the Shell petrol station and back onto the highway. Drivers can also use the road behind the Shell station to rejoin the Thika Superhighway.

KeNHA said the closure is needed to pre-assemble a bridge superstructure and later hoist it into place. "The closure is to allow for pre-assembly of the bridge superstructure and subsequent hoisting," the notice said, as quoted by The Star. A Kenyans.co.ke photo caption calls the structure the Kihunguro footbridge.

The authority asked motorists to take care near the work area, follow the designated diversion routes and cooperate with police officers and traffic marshals on site. "KeNHA informs the public of a temporary traffic disruption due to the closure of the Thika-bound service lanes at Kihunguro," the notice said, as quoted by Kenyans.co.ke.

In a notice dated 13 October 2025, KeNHA announced the closure of both the Nairobi-bound and Thika-bound service lanes at Kihunguro from 20 October to 20 December 2025 to build the column bases and stub columns for a new footbridge, The Star reported on 14 October 2025. That notice told Thika-bound drivers to use the service lane only as far as the Shell petrol station, then join the main highway for a few hundred metres before returning to the service lane.

Kenyans.co.ke also reported wider maintenance and improvement projects on the Nairobi–Thika route. The planned works include bus bays at Roysambu and Githurai on the Nairobi–Ruiru section, and a climbing lane at Blue Post in Thika and bus bays at Witeithie on the Ruiru–Thika section.

KeNHA's headquarters can be reached on 0204954000 or 0700423606, and its toll-free line is 0800211244, according to the authority's website.
