Kenya National Highways Authority has said it will extend the temporary closure of the ramp from Waiyaki Way to Forest Road to September 20.
The ramp was to be closed only for 34 days but has now been extended.
“This is to pave way for the ongoing construction of the Nairobi expressway along Waiyaki way. Motorists are kindly advised to use alternative rotes,” Director general David Muchilwa said.
In a notice on Sunday, Muchilwa apologized for any inconvenience that may be caused.
“The authority endeavors to provide an efficient safe and reliable road network,” he added.
Closures will worsen traffic jams on the highway already overwhelmed by the construction.
The expressway construction has turned Nairobi into a nightmare with cars piling up for hours during rush hour.
Overlapping and resulting accidents have become a common feature, despite deployment of additional traffic police. Billions of shillings have been set aside for traffic management.
KeNHA had on June 6 directed the contractor in charge of the Sh65 billion project to implement a better traffic management system on Mombasa Road.
This came after concerns regarding increased traffic snarl-ups on the major highway were raised by motorists as well as claims of poor traffic management by the contractor.
The 18.5km road starts at Jomo Kenyatta International Airport and ends at the James Gichuru Junction along Waiyaki Way in Westlands. The official name is the JKIA-James Gichuru Expressway.
In January 2021, Transport Cabinet Secretary James Macharia gazetted the expressway as a toll road.
It is to be completed in 2022.
