The Thika Superhighway will be partially closed from December 12-17, the Kenya National Highways Authority has announced.
The authority said the road will be closed at the Juja Highpoint (Centurion) to enable the construction of a footbridge.
KeNHA said the public should expect traffic disruption as a result of the closure.
“Nairobi-bound traffic will use a diversion behind Lexo petrol station before rejoining the Superhighway, while Thika-bound traffic will use a diversion behind Centurion hotel before rejoining the Superhighway,” the authority said.
Motorists have been requested to exercise caution around the work areas, and follow the proposed traffic management plan and cooperate with the police and traffic marshals on site.
In December 2022, then Transport Cabinet Secretary Kipchumba Murkomen ordered that at least four footbridges be constructed along the Thika Superhighway.
He said installation of the footbridges will ease movement of pedestrians and curb rampant accidents along the busy highway.
KeNHA will build the bridges at Juja Highpoint stage near Centurion hotel, Kihunguro section, Juja Mona Park area, and Clay Works/Northlands.
"Additional footbridges are planned for installation at different sections of Thika Superhighway and engineering design has been done," Murkomen said then.
He was responding to questions by Ruiru MP Simon King'ara on the state's safety measures along Thika Road.
Murkomen said the government would also employ multiple measures to curb accidents along the busy highway.
They include sensitisation of the public and road users on the use of designated crossing points and passenger picking and dropping points, and installation of road signs.
He also said the government was improving marking of road bumps to enhance the safety of road users.
"In order to encourage pedestrians to use the footbridges consistently, improved lighting has been installed to enhance security," he said.
"Fencing along the median of the superhighway has been done (at critical areas) and is constantly under maintenance and repair by the PBC (Performance Based Contracting) contractors to ensure pedestrians use designated crossing points."
