Alternative Routes for Motorists as KeNHA Announces Closure of Thika Superhighway
Motorists travelling between Nairobi and Thika have been advised to use alternative routes during the one-week closure
Traffic heading to Nairobi CBD from Thika will use the Globe Overpass, while vehicles from Thika along University Way will be diverted to Prof. Wangari Maathai Road.
Those travelling from Thika to Kirinyaga Road and OTC are advised to use Ring Road.
Traffic from Kipande Road to the CBD should take Limuru Road (Fig Tree) before joining Prof. Wangari Maathai Road.
Vehicles coming from University Way or the CBD and intending to make a U-turn at Globe Roundabout to head to Guru Nanak should follow the designated U-turn route.
Motorists have been requested to exercise caution around the work areas and follow the proposed traffic management plan as well as cooperate with the police and traffic marshals on site.
Heavy Traffic
Motorists experienced heavy traffic near the Globe Roundabout on Thursday, with many spending long hours on the road.
Those unaware of the alert from KeNHA were left wondering what was happening.
Sholla Ard was, however, quick to offer a solution to the traffic issue:
“I’ve been thinking about the traffic nightmare at Globe Roundabout and Thika Superhighway. The core problem is simple: too many vehicles competing in one circle. Instead of forcing all traffic into a roundabout, the solution is what modern cities do: vertical separation. Remove the roundabout completely. Build a multi-level interchange,” noted Ard on X.
Sarah Saash on X threw some shade after it was apparent that Thika Road was in a mess. “I hear Nairobians using Globe Roundabout are walking into town like wildebeest migration could you confirm if that’s true! Suffering is constant in this mafuriko city, but I came here to say good morning, though,” she said.
On the other hand, Schocards wondered why KeNHA chose to send the advisory at night. “We appreciate the good work you’re intending to do, we applaud you, but why issue a statement for works & begin execution on the same day?” retorted @schocards.

Meanwhile, KeNHA reminded the public that the Marigat – Loruk (B17) Road between Km 29+800 and Km 40+000 is still closed since 21st August, 2025.
This is due to flooding of the road caused by the fast-rising water levels of Lake Baringo.
Motorists are urged to continue utilising the alternative diversion route at Km 29+200 on the Marigat – Loruk (B17) Road, which will intersect the Loruk – Chemalingot at Km 2+400.
“The Authority cautions road users against any attempts to use this section of the Road in the interest of their safety,” KeNHA said.
Roads Opened to the Public
Elsewhere, the authority informed the public that the Kaplong-Kisii Road is now open to traffic.
This follows the closure of the road section on March 7, 2026, due to flooding at the Kipsonoi River Bridge in Mugeni, between Sotik and Chebilat.
The Authority, however, appeals to motorists to approach the bridge section with caution, as there may be flooding due to stormwater upstream of the Kipsonoi River.
At the same time, KeNHA announced that the Mai Mahiu–Suswa–Narok (B7) Road is now open to traffic.
The road section was previously closed on 7th March 2026 due to flooding and silt deposition at Kedong Ranch near Suswa.
However, motorists have been urged to exercise caution, particularly between Naivasha ICD (Km 14) and Suswa Ranch (Km 39), as rains continue to affect the area.
