Motorists are being advised that the Fisher Lane roundabout on the A1 will be closed for three weeks to allow for resurfacing works on the newly widened roads.
The Highways Agency pinch point scheme at Seaton Burn in North Tyneside is in the final few weeks of work.
The agency said when complete the scheme will cut congestion.
Highways Agency assistant project manager, Steve Bishop, said: “Drivers will soon benefit from the improvements at the Seaton Burn junction.
“The weekend closures are critical for surfacing work to take place. The roundabout must be closed as there is not enough room for surfacing machinery and drivers to safely use the roundabout at the same time.”
The closures will take place from Friday, October 24, from 8pm to 6am, on Monday, October 27, and again from November 7 to 10, and 14 to 17.
