Further road closures have been put in place as the £102 million scheme to dual the A11 between Fiveways roundabout and Thetford continues.
The B1106 between Elveden Inn and Center Parcs will close from 10pm on Wednesday to 6am on Thursday.
The Highways Agency has advised that the closure will add 30 minutes to journey times.
The B1112 which joins the A11 to the A1065 remains closed as does the C616.
Work on the project is scheduled for completion in December.
