The Kenya National Highway Authority has advised motorists to refrain from attempting to cross the Athi River Bridge until the water levels recede to safe levels.
In a statement on X, Kenha advised motorists of a significant traffic disruption resulting from ongoing rains.
“Athi River flooded early this morning and the bridge linking Kitengela to Mombasa Road along Namanga Road is impassible,” Kenha said.
“Take an alternate route by diverting through the East African Portland Cement junction via Athi River to Devki.”
On Wednesday, motorists were stuck along Nairobi-Namanga Road after it flooded due to flash floods.
A spot check by the Star established that several passengers and motorists plying the route were caught off guard by the floods as they headed to Nairobi and Namanga general directions.
They got stuck in their vehicles between River Athi Bridge near Shell petrol station and Shalom Community Hospital in Athi River, Machakos County.
The situation has since led to a snarl-up that continues to pile.
The said Bridge has swollen with the adjacent old bridge submerged by the flood waters.
Athi River East subcounty police commander Anderson Mbae said the situation had been caused by the swollen River Athi which has busted its banks.
Mbae said motorists plying Nairobi - Namanga Road off the busy Nairobi - Mombasa highway had diverted to the alternative Devki - Namanga Road.
"River Athi is maximumly swollen, but we have no reported incident report. The traffic to and from Namanga general direction is being diverted to Devki bypass on the Nairobi-Mombasa highway," Mbae told the Star by phone early Wednesday.
