    Work gets under way

    We started work in February on our project to increase the size of the roundabout at Guyhirn junction. We’ve started with our vegetation clearance adjacent to the Guyhirn roundabout at Old March Road, ahead of starting main construction work in April 2021. We’re aiming to complete the main construction work in April 2022.

    In the meantime, we have launched a virtual exhibition area where you can find out more about the project and see regular updates during its construction. 

    Road closures

    For the safety of the public and our workers, we will need some 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.

    Overnight road closures

    We’re now planning to carry out the following overnight road closures during May 2021:

    • We will need to close A47/Fenn Road from the existing Guyhirn roundabout to Gull Road/A47 junction between 8.00pm and 6.00am over two nights.
    • We will need to close the A141 entrance and exit on the Guyhirn roundabout between 8.00pm and 6.00am for one night.
    • We will advertise the closure dates on signs at the roadside two weeks ahead of the closures to give drivers advanced notice.

    Traffic diversions will be in place when the road is closed - view the routes in the Traffic management section below.

    Surveys have been completed

    Survey work has now been completed. We are making preparations to start construction work in early 2021.

    Ground investigations and surveys

    We will be undertaking ground investigations and survey works around the Guyhirn junction in February and March 2020 lasting for five to six weeks.

    We aim to minimise the impact on the nearby community and environment during these important investigations, but there will be some drilling which may be noisy for those living nearby. Where possible works will be carried out during the day but as we have restricted access to the area directly adjacent to the A47, it will be necessary for us to carry out some works overnight.

    Please be aware that this may increase journey times through this route.

    The survey results will be used in the further development of our design to improve this junction.

    Public information events will take place once the scheme design has been developed further.

Project information

Overview

We’re improving the A47 in six places between Peterborough and Great Yarmouth as part of a £300 million-plus investment, including the Guyhirn junction.

We’ll be making changes to the Guyhirn junction between the A47 (Fen Road to South Brink) and the A141 (March Road) which is used by over 20,000 vehicles a day and experiences high levels of congestion. The junction improvements aim to reduce congestion, improve journey times and increase safety.

Our project on the Guyhirn junction aims to increase the size of the roundabout by creating two lanes on all approaches to the roundabout. This will include an additional lane over the existing carriageway on the River Nene Bridge. Towards the end of the project there may be an opportunity for us to carry out additional bridge maintenance on the River Nene bridge.

Following our Preferred Route Announcement (PRA) in 2017, we undertook a variety of technical and traffic surveys to help us finalise our design for the project. As part of this we made some changes to our design which means it now falls within the existing highway boundary. This means that we do not need to obtain planning permission as we originally thought, saving time and enabling us to start work earlier than planned.

 

With this scheme, we’re aiming to:

  • improve safety and reduce collisions
  • support future employment and housing developments
  • increase capacity at the junctions and improve traffic flow
  • reduce delays and make journey times more reliable
  • improve connectivity for local people living and working near the scheme
  • improve amenities for cyclists and pedestrians

A47 Guyhirn junction improvement - 13 March 2017 to 21 April 2017

During construction, our aim is to provide a safe environment for all those working on or travelling through our roadworks, while keeping delays to a minimum. To help that, we’ll have the following in place:

Narrow lanes

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

Speed limit

We will put in place a temporary 30mph speed limit through the roadworks for safety reasons.

Temporary roundabouts

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

Diversions for road closures south of Guyhirn roundabout

A47 west closed:

Head west on the A47 until the A1139. Join the A1139 and travel south to the A605. Follow the A605 and travel east until the A141 and head north until re-joining with the A47.

A47 east closed:

Head south on the A141 and then exit to the A605 and travel west to the A1139. Follow the A1139 heading north until re-joining the A47.

A47 north closed:

Head west on the A47 until the A16. Join the A16 and travel north to the A151. Join the A151 heading east until the A17, join the A17 and travel east and then re-join the A47.

A47 south closed:

Head north on A47 until the A17. Join the A17 and travel west until the A151. Follow the A151 West to the A16, join the A16 and travel south until you re-join the A47.

Working hours

To allow us to complete our work efficiently and limit disruption to traffic, we’ll be working during both day 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.

Public footpaths

We will keep public footpaths open for walkers and cyclists, although we’ll need to make some slight changes to the existing routes.

Lighting

We will remove the existing streetlights and replace them with temporary lights throughout the construction period, to help maintain safety for all road users.

Noise

At times, some of our work will be noisy. We’re working closely with local communities who may be affected to manage this wherever possible, particularly around Old 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.
