The A47 Guyhirn junction improvement is one of six schemes National Highways is completing along the 115-mile A47 route between Peterborough and Great Yarmouth, and work is due to finish this spring.
National Highways Senior Project Manager for Guyhirn, Jonathan Donlevy, said: “The Guyhirn roundabout is a key junction along the A47 which connects people, communities and businesses in Cambridgeshire and Norfolk through to Kings Lynn and the A1(M). The upgraded junction will not only help to reduce delays and make journey times more reliable but will provide additional capacity which will be crucial to the local and national economy.”
Galliford Try Project Manager for Guyhirn, Tim Walker, said: “It’s great to see our work at the junction nearing its completion. I appreciate that roadworks can be disruptive, so I want to thank all those who have been affected for their patience, and hope that they are looking forward to enjoying the benefits of this improved junction shortly.”
The completion work will see seven successive weekend closures, from 8pm Friday until 6am Monday, starting from the first weekend of February.
Guyhirn junction is used by more than 20,000 vehicles a day and experiences a high level of congestion. The junction improvements – which includes increasing the size of the roundabout and creating two lanes on all approaches to the roundabout – will help to reduce congestion, improve journey times and increase safety.
In addition to the Guyhirn scheme, three sections of the A47 will be improved to dual carriageway and another junction will be improved. In Norfolk the A47 will be dualled between Blofield and North Burlingham and between North Tuddenham to Easton, and in Cambridgeshire between Wansford and Sutton, while the A11 Thickthorn junction interchange will also be improved.
