About the Guyhirn junction project

We will be carrying out overnight works on the A141 March Road, A47 Fen Road and A47 South Brink between Tuesday 31 August and Friday 17 September.  Traffic will be controlled with 3-way traffic lights between the hours of 20:00hrs and 06:00hrs each night.  The roads will remain open at all times however there could be delays. 

The A47 is an important connection, linking the cities of Norwich and Peterborough, the towns of Wisbech, Kings Lynn, Dereham, Great Yarmouth and Lowestoft and a succession of villages in what is largely a rural area. As part of a multi-billion investment to improve journeys on England’s major A-roads and motorways, the Government is funding a package of six projects on the 115-mile stretch of the A47 between Peterborough and Great Yarmouth. Together the projects will convert almost eight miles of single carriageway into dual carriageway and improve key junctions along the A47 road.

The A47 road improvement projects are: 

  • A47/A141 Guyhirn junction 
  • A47 Wansford to Sutton dualling 
  • A47 North Tuddenham to Easton dualling 
  • A47/A11 Thickthorn junction 
  • A47 Blofield to North Burlingham dualling 
  • A47 Great Yarmouth junction

We’ll be improving Guyhirn junction between the A47 (Fen Road to South Brink) and the A141 (March Road). This road is used by over 20,000 vehicles a day which can lead to traffic jams. The changes to the junction aim to reduce congestion, improve journey times and increase safety.

Following our Preferred Route Announcement (PRA) in 2017, we made some changes to our design which means it now falls within the existing highway boundary. This means that we did not need to obtain planning permission and we’ve been able to start work earlier than planned.

The design in detail

We’re making the roundabout bigger by creating two lanes on all approaches to the roundabout. This includes an additional lane on the existing road on the River Nene Bridge. During the project we may be able to carry out additional maintenance on the River Nene bridge. This means we won’t have to do more work next year.
