Why are you improving the A47/A141 junction at Guyhirn?

The A47 (Fen Road to South Brink) and the A141 (March Road) is used by over 20,000 vehicles a day and experiences high levels of congestion. Without our improvements, we anticipate the junction will be over capacity by 2021 on the A47 approaches. By 2031 this could be further exacerbated by potential future developments in the area.

Our improvements to the junction will:

  • reduce delays and queuing traffic by increasing the size of the Guyhirn roundabout
  • improve safety by increasing visibility for drivers when they enter the roundabout
  • improve pedestrian crossings and footpaths, particularly between March Road, Guyhirn village and local amenities
  • support future employment and housing developments by making journey times more reliable
  • improve safety by increasing visibility for drivers when they enter the roundabout

What does the scheme involve?

We’ll be making changes to the Guyhirn junction between the A47 (Fen Road to South Brink) and the A141 (March Road). The junction improvements aim to reduce congestion, improve journey times and increase safety.

As part of our work we will: 

  • increase the size of the existing A47 / A141 roundabout, creating two lanes on all approaches to the junction
  • temporarily remove Gull Road/A47 exit keep left turn bollard with partial removal of existing island kerbs enabling right turn during closures
  • relocate the electric and telecom apparatus from the north to the south part of the bridge
  • resurface the existing carriageway on the River Nene Bridge 
  • introduce signalised pedestrian crossing points on A141 and A47 (near the existing stairs to the north)
  • remove the path that currently connects March Road and A47 (near the roundabout), and redirect users to the new crossing poin
  • remove the northern footpath on the bridge to accommodate the proposed two lanes on approach to the roundabout and direct users to the southern footpath on the bridge and the associated new crossing points.

How will these improvements reduce the delays I experience on my daily commute through the junction?

We’re increasing the size of the existing A47 / A141 roundabout and creating two lanes on all approaches to the junction which will reduce the amount of traffic passing through the junction. We expect the new junction to increase capacity by 18% and reduce journey times by up to 4 minutes.

When will you start work and how long will the work last?

We started work in February 2021 and will be open to traffic by April 2022. Construction will last approximately 14 months. 

What hours will you be working?

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.

Will there be any road closures?

For the safety of the public and our workers, we will need some road closures during spring and then in autumn 2021 for resurfacing. Traffic will need to use the diversion routes shown here. 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. More details about any road closures can be found here.

We will give advance 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. Diversion routes for road closures to the south of the Guyhirn roundabout.

Will there be traffic lights on the main routes through the junction during the work?

Traffic lights will be required to allow us to complete our work safely. We are maintaining the capacity of all approaches by using some lanes that are narrower than usual to create space for construction activities. These will be clearly marked by road markings, studs, temporary barriers and traffic cones.

  • We’ll also build a temporary roundabout to replace the existing Guyhirn junction roundabout and this will result in a change to the road alignment. Following our discussion with the local authority, we are not planning to install a temporary roundabout at Gull Road due to safety, vehicles will continue to turn left when exiting Gull Road. With the modification to the central island at Gull Road, when the roundabout is closed drivers will be able to exit the junction by turning right on to the A47. 

Our key objective during the construction period will be to keep customer journeys moving along through the construction area.


Why are there reduced speed limits within the works area?

Safety is Highways England’s top priority; reduced speed limits are necessary for the safety of both road users and road workers. Roadwork creates a different environment for drivers in which reactions and behaviour change; for that reason, a lower speed limit of 30mph is necessary.

Will buses be affected during construction?

We’ll need a few night closures and route diversions during spring 2021 to allow us to set up a safe work site. We’ll also need some closures at the end of the construction period to undertake resurfacing. These closures and diversions will affect all traffic including buses. We’re working closely with bus companies, haulage companies and emergency services to keep them informed of diversions and potential impacts to their routes. 

What provisions are being made for pedestrians and cyclists?

We’re removing the northern footpath on the bridge to make room for two lanes of traffic on the approach to the roundabout. The southern footpath will remain in place with new signalised crossing points on the A47 and the A141 roads. We also need to remove the path that connects March Road with the A47. Pedestrians and cyclists will be directed to use the A141 signalised crossing at the entry point of March Road.

How will you protect my property from noise and air pollution?

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, a permanent acoustic and light barrier will be constructed at the south side of the roundabout adjacent to March Road. We have planned our construction times to ensure there will be no significant effects on the adjacent Nene Washes nature reserve and reed beds.
