Traffic & diversions

The next stage of work includes lining, placing studs on the road, resurfacing, and work to repair the River Nene bridge. These closures are for the approach to the roundabout on the closed road only. The roundabout will remain open for drivers travelling to and from the junction using the other two roads.

Road closures 

Where: The A47 Fen Road will be closed overnight for two nights this week, from Gull Road to the Guyhirn roundabout, for essential works.


  • From 8pm to 6am on Wednesday 16 and Thursday 17 March.

Diversion route:

  • Eastbound traffic will exit the Whitepost roundabout at Thorney onto the A1139, then continue onto A605 Fletton Interchange, take the slip road onto the A605 through Whittlesey and Coates to the A141, and re-join the A47 at Guyhirn.
  • Westbound traffic will follow this diversion in reverse.

Where: All the approaches to the Guyhirn roundabout (South Brink, Fen Road, and the A141 March Road south to the A605)

Diversion route for the Fen Road closure is as above.

Diversion route for the South Brink closure:

  • Eastbound traffic will follow the A47 west to Peterborough and join theA16 north to Sutterton, then take the A17 east to King’s Lynn, and re-join the A47 to return to Guyhirn.
  • Westbound traffic will follow this route in reverse. 

Diversion route for the A141 closure:

  • Northbound traffic will take the A605 westbound through Whittlesey towards Peterborough, then take the A1139 and the A15 north to pass Peterborough, and then the A47 eastbound through Thorney to reach the Guyhirn roundabout.
    Southbound traffic will follow this diversion route in reverse.


For the safety of the public and our workers, we do need some road closures for resurfacing. Traffic will need to use the diversion routes that are provided on this page.

Some of the diversions may be long, but we will aim to only close one arm of the roundabout at a time and limit road closures to night times between 8:00pm to 6.00am. We will provide more details closer to the time. We will give advanced notice of these road closures on the project website, via social media and early warning road signage. We will share regular progress updates with stakeholders, local councils and residents.

Please check for possible road closures and plan your route ahead of your journey.

Temporary traffic lights

Three-way traffic lights will be in place on all approaches to the Guyhirn roundabout from Sunday 8th August – Friday 13th August, 8.00pm – 6.00am.

Lane Closures

To carry out our work safely, we’ll need some overnight lane closures (8.00pm – 6.00am) between 12 April to 30 April 2021 inclusive. Traffic will still be able to use the junction and there will be temporary traffic lights and road markings.

During these dates we will be temporarily removing the existing ‘keep left’ bollard and the island kerb at the exit of Gull Road/A47. Removing these will allow traffic to turn right when the roundabout is closed for our work. Changing the turning out of Gull Road will help reduce congestion during the roadworks. In addition, we’ll put in safety barriers so that we can start removing the existing roundabout.
