Construction works

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) 


  • 8pm on Friday 18 March to 6am on Monday 21 March. 

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.

We started our construction work in February 2021 and aim to finish in April 2022. During construction, our aim is to provide a safe environment for all those working on or travelling through our roadwork. We’ll also try keep delays to a minimum and keep you informed about our work.

Narrow lanes

To keep traffic moving, we’ll keep all the traffic lanes on the road open but reduce the width of the lanes. This means we can minimise disruption to motorists.

Speed limit

We’ll put a temporary 30mph speed limit in place through the roadwork for safety reasons.

Temporary roundabouts

We will install a temporary, smaller roundabout at Guyhirn junction. This will help keep traffic moving whilst we construct the larger improved roundabout. 

Lighting and noise

We will remove the existing streetlights and replace them with temporary lights during our construction works, then replace these with permanent low energy lights when we complete our work. At times, some of our work will be noisy. We will work closely with local communities who may be affected to manage this wherever possible, particularly around March Road. Towards the end of the project, we’ll build a permanent acoustic and light barrier at the south side of the roundabout adjacent to Old March Road. 


We have planned our construction times to ensure there will be no significant effects on the Nene Washes nature reserve and reed beds.

Public footpaths

We will keep public footpaths open for walkers and cyclists, although some slight changes to the existing routes will be necessary. We will communicate this information on signs by the roadside before we make any changes.

Working hours

To allow us to complete our work efficiently and limit disruption to traffic, we’ll be working during both daytime and night time from Mondays to Saturdays and occasionally on some Sundays. Our daytime work hours will be between 7.00am and 7.00pm. Our night time hours will be between 8.00pm and 6.00am when there is less traffic. 

Other works in the area

We will be working closely with parish councils and Cambridgeshire County Council to coordinate our construction work with their projects at Broadland Road and Elm High Street/A47 Wisbech to reduce any impact on journey times. Where possible, we intend to use shared signage with Cambridgeshire County Council to help people on their journey. We will also share information with our stakeholders, bus companies and hauliers as the project develops.
