There are deep puddles near the junction with Wentworth Street this afternoon.
It is not the first time this year the road has been flooded - in February a burst water main caused the road to be closed for several days, and heavy rain in the summer also caused small floods.
A yellow weather warning is currently in place with heavy rain showers expected through the afternoon and evening.
A spokesman for Anglian Water said: “The recent heavy rain can overwhelms the drainage systems which is why flooding can happen as the drains can’t cope with sheer volume of water. The drainage systems are managed by a number of organisations from the council, private drainage and ourselves and we work very closely with all parties involved when it comes to flooding.”
A spokesperson for Peterborough City Council, said: “The flooding in Bourges Boulevard has been caused following an extreme amount of rainfall, which can happen to any drainage system if capacity is exceeded. We are looking at potential options to see if this issue can be alleviated in future, but in the meantime would advise motorists to take extra care.”
