Part of the A605 is to close over the weekend to allow for works to improve the safety of the road where there have been several fatalities this year.
The A605 will be closed between the Peterborough Services and Elton Junction (B671) from Friday, October 27 at 8pm to Monday, October 30 at 5am.
A Cambridgeshire County Council spokeswoman said: “We are working closely with Northamptonshire Highways who have a road closure in place on these dates to undertake resurfacing and vegetation cut back along the A605 from Warmington to the Elton junction.
“Extending this closure up to the services roundabout will mean a single temporary road closure.
“A local diversion route will be in place via Overend - Oundle Road. The diversion route for through traffic will be in place via A1(M) – A14.”
