Denise Gable sent a photo after the A1123 road at Earith Bridge was closed in both directions, between the B1050 Shelfords Road and Bridge End.
The Environment Agency issued a flood warning and reminded drivers not to risk driving through floods and said: "Due to the uneven surface of the road, water may be deeper in places than it appears."
Earlier in the week flooding affected the Riverside Parks in Huntingdon and St Neots as well as the Welney Wash.
Carol Holt, flood duty manager at the Environment Agency, said: "Following wet weather over the past week and with more rain forecast, there is a continued risk of flooding in parts of England.
"We continue to monitor rainfall and river levels closely."
