The Kenya National Highways Authority (KeNHA) will close the Thika-bound service lanes at Kihunguro on the Thika Superhighway for more than a month. The closure makes way for bridge construction. It starts on Sunday, November 15, and runs until Sunday, December 20, 2026, according to a KeNHA public notice dated November 8, Capital FM reported.
KeNHA Director General Luka Kimeli announced the plan on Monday, Kenyans.co.ke reported. He said contractors need the space to pre-assemble the bridge superstructure and then hoist it. Tuko put the closure at 35 days.
Motorists driving from Nairobi towards Thika will have two diversions. One runs via Shell Petrol Station and back onto the highway. The other passes behind the station before rejoining the Thika Superhighway.
KeNHA asked drivers to take care near the work site and follow the temporary traffic plan. Police officers and traffic marshals will be deployed to guide vehicles through the section, according to Kenyans.co.ke. "Motorists using this road are requested to exercise caution around the work areas, follow the proposed traffic management plan, and cooperate with the police and traffic marshals on site," the authority said.
The Kihunguro works are part of wider projects on the Nairobi-Thika route to improve road safety and ease traffic, Kenyans.co.ke reported. Plans include bus bays at Roysambu and Githurai on the Nairobi-Ruiru section. These will give matatus set places to pick up and drop off passengers.
Further up the road, the Ruiru-Thika section is earmarked for a climbing lane at Blue Post in Thika and bus bays at Witeithie, the outlet said.
