Transport and Infrastructure Cabinet Secretary James Macharia has temporarily banned public service vehicles carrying more than seven passengers from using Nairobi Expressway.
In a statement on Wednesday, Macharia said the government will further introduce a 110km/h speed limit and install rumble strips to curb increasing accidents on the road.
"This is to warn drivers to slow down as they approach the various toll gates. The maximum speed limit on all public roads in Kenya is 110km/h," the CS said.
Cameras on Expressway
Macharia said speed cameras have also been introduced on the road to check speed limits.
"All motorists are required by law to adhere to the stipulated speed limits. We have installed speed cameras to enhance the enforcement of speed limits," he said.
The new highway has recorded two fatal accidents in the past month.
