A47 Guyhirn junction
We’re improving the A47 Guyhirn junction by increasing the size of the roundabout to ease congestion and cope with increasing traffic levels.
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
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:
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.
We will put in place a temporary 30mph speed limit through the roadworks for safety reasons.
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.
Diversions for road closures to north and west of Guyhirn roundabout
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.
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.
We will keep public footpaths open for walkers and cyclists, although we’ll need to make some slight changes to the existing routes.
We will remove the existing streetlights and replace them with temporary lights throughout the construction period, to help maintain safety for all road users.
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.
