Transport has been paralysed in parts of Kwale after heavy rains swept away a bridge at Lunga Lunga area.
Most of the roads have been cut off and rendered impassable.
The rains have also flooded River Ramisi making it impossible for people and vehicles to cross.
Area deputy county commissioner Josphat Biwott said travellers are now forced to follow Lunga Lunga-Horo Horo route which is long and expensive.
The road is among those under construction by the national government.
