Residents on Friday said the victims were crossing the bridge when they met their deaths.
The five— four Standard Gauge Railway construction workers and a woman— were trying to cross the bridge that links Kandisi and Ongata Rongai on Thursday evening when they were swept by the floods.
The bridge, which is still under construction, was funded by the county government of Kajiado.
According to witnesses, the dead were part of Rongai residents who were caught the heavy rains on the Kandisi side of the seasonal river.
The rains that pounded several parts of Kenya on Thursday wreaked havoc for commuters and motorists in towns, including the capital Nairobi.
A resident, who sought anonymity for personal reasons, said a pastor who was with the four men escaped death narrowly after he refused to join them in crossing the swollen river.
