The work to increase the size of the roundabout at Guyhirn junction started earlier this year - but lane closures will start today as the project moves forward.
A spokesman for Highways England said: “For the safety of the public and our workers, we will need some lane closures (8pm – 6am) 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.”
A number of road closures will also be in place in May, on dates yet to be decided.
The spokesman said: “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.”
