Thika Superhighway Service Lanes to Close for 5 Weeks at Kihunguro

Motorists using the Thika Superhighway should expect five weeks of traffic disruptions after the Kenya National Highways Authority (KeNHA) announced plans to close the service lanes at Kihunguro.

KeNHA Director General Luka Kimeli said on Monday, November 9, that the closure would allow contractors to build a bridge, including assembling and hoisting its superstructure. The closure will run from Sunday, November 15, to Sunday, December 20, 2026.

“KeNHA informs the public of a temporary traffic disruption due to the closure of the Thika-bound service lanes at Kihunguro along the Thika Superhighway from Sunday, November 15, 2026, to Sunday, December 20, 2026,” the Authority announced.

During the works, motorists travelling from Nairobi towards Thika will need to use alternative routes. KeNHA said drivers could divert via Shell Petrol Station and rejoin the superhighway or use the road behind the station to reconnect with the highway.

“The Nairobi-Thika traffic will be directed to use the diversion via Shell Petrol Station back to the highway or behind Shell Petrol Station to rejoin Thika Superhighway as an alternative route during this period,” the authority stated.

KeNHA urged motorists to slow down near the construction site, follow the temporary traffic plan, and cooperate with police officers and traffic marshals, who will direct vehicles through the affected area.

The Kihunguro project is part of wider maintenance and improvement works along the Nairobi-Thika route aimed at improving road safety and traffic flow. Planned upgrades include bus bays at Roysambu and Githurai, where public service vehicles can pick up and drop off passengers.

KeNHA has also earmarked further work on the Ruiru-Thika section, including a climbing lane at Blue Post in Thika and bus bays at Witeithie.
