A number of Cambridgeshire Fire and Rescue crews as well as neighbours in Lincolnshire, police and ambulance crews are carrying out training exercises at the Queensgate roundabout, close to the bus station and Cowgate.
A small section of pathway has been taped off but the road remains fully open.
The fire service confirmed: “Today our crews, along with partner agencies and other emergency services, will be carrying out a training exercise near to the Queensgate area in Peterborough.
“There will be lots of emergency vehicles in the area, but please don't be alarmed.”
