The first phase of highways improvements on and around the Tyne Tunnel approach is now complete.
The work, which involved replacing worn out road surfacing on the A185 as well as a junction upgrade, finished as scheduled on Friday.
The two-week long scheme necessitated road closures and diversions via the Lindisfarne roundabout, which has recently undergone major improvement works.
Councillor Allan West, Lead Member for Housing and Transport, said: "The A185 works obviously had a knock-on effect on traffic flow through Lindisfarne.
"However, now that the first phase of that work is over and the roads are fully open, we expect people to see the full benefits of the completed Lindisfarne project.
"The scheme was designed to enhance safety, speed up journey times and reduce congestion and motorists should start to notice these improvements."
The £400,000 works on the A185 included resurfacing the road from the southern Tyne Tunnel portal to Jarrow Slake and improvements to the A185/Church Bank junction.
The second phase of the A185 programme will get underway week commencing August 21. The works, which will involve improvements on the A185/Howard Street approach to the Tyne Tunnel, are scheduled to last a week and will involve road closures, however these will be overnight.
Cllr West added: "As well as replacing the surfacing, the other aims of this scheme are to improve safety and increase vehicle capacity on the Tyne Tunnel approach, which as anyone who uses this route regularly will know, can be something of a bottle neck.
"During the first phase, the council took the opportunity to clean the road gullies and drainage system as well as carrying out general maintenance, for example on the crash barriers and cutting back trees.
"As always, we thank motorists for their patience."
