North Tyneside Council is spending £7.2million to improve safety and reduce congestion at the east end of the A1058 Coast Road.
Work to create two lanes heading from Billy Mill roundabout to the coast on Beach Road is expected to be finished this weekend.
As part of the project, Beach Road will be closed overnight between 8pm today (Thursday) and 6am on Friday to allow it to be completed.
It will be closed the following night, from 8pm on Friday to 6am Saturday for any remaining road markings to be added.
Works to install an improved footpath and cycleway on the northern side of Beach Road will also be finished shortly, which will complete the first phase of the Coast Road Improvement Project.
Coun John Harrison, cabinet member for housing and transport, said: “This is a significant milestone in the project and I am delighted this phase is almost complete.
“By doubling the capacity of the road, we can help keep traffic moving and reduce journey times – and most importantly, improve safety.
“We appreciate the disruption roadworks can cause to drivers and we’d like to thank the public for their patience.
“If they haven’t already done so, I’d encourage the public to sign up to our dedicated newsletter for the project so they can stay up to date with the work.”
The next phase of the scheme will involve replacing Billy Mill roundabout with a signalised junction.
The eastbound lanes have been put in place prior to starting work on the roundabout to help maintain traffic flows during the second phase of work.
The project is being delivered by Capita on the council’s behalf.
