Transport at the Likoni Ferry crossing channel has been grounded to pave way for a critical multi-agency rescue mission.
Closing the channel for the activity, the Ferry Services Managing Director Mr Bakari Goa noted that all in-bound and out-bound ships crossing through the busy channel would be affected.
Rescue operations begin three days after a tragic incident happened in which a woman Ms Mariam Kigenda and her 4-year-old daughter Amanda Mutheu plunged into the ocean.
Goa said the rescue mission headlined by the Kenya Navy will take at least 30 minutes to retrieve the bodies and the car.
He also added that the ferry management had partnered with Kenya Redcross to offer ambulance services for accident victims at the Likoni and Mtongwe crossing channels.
The Likoni channel transports over 300,000 passengers each day with thousands of cars crossing over the troubled waters.
Initial witness accounts indicate that the two accidentally reversed into the ocean, a few metres from the landing bay.
Terrified passengers watched in disbelief as the two sank deep into the ocean to heights below 60 metres.
Monday evening, the family and friends of the deceased were prevented from hiring private divers to retrieve the bodies of the two after officers at the Kenya Navy advised that it could be risky.
Nairobi Governor Mike Sonko would dispatch a rescue crew in a chartered helicopter to help with the rescue after it emerged KFS lacked skilled divers for the mission.
