Highways improvement works on and around the Tyne Tunnel approach in South Tyneside are due to get underway next week.
The two-phased project will replace worn out surfacing, as well as improving safety and vehicle capacity on the A185 corridor.
South Tyneside Council is advising motorists that the scheme will involve road closures in order to complete the work as quickly and safely as possible.
The first phase, which is scheduled to start on Monday July 24, involves resurfacing the A185 Jarrow Road from the southern Tyne Tunnel portal to Jarrow Slake (Pilgrim's Way) and improvements to the junction of the A185 and Church Bank.
These works will take around two weeks to complete and during this time, 24-hour week-day road closures will be in place. No closures will be in place at weekends. Diversion routes will be in place as required with the main diversion route being via the completed Lindisfarne Junction when leaving or joining the A19.
The second phase, which is envisaged to start on 21st August and is scheduled to last around one week, will involve improvements on the A185/Howard Street approach to the Tyne Tunnel. This will involve road closures but at this time, it is planned that these will be overnight only.
Access to the Bede Industrial Estate will be maintained at all times from the A194 Arches approach.
Cllr Allan West, Lead Member for Housing and Transport, said: "The resurfacing works are necessary as the current surface is reaching the end of its effective life and is starting to fail in places.
"As well as replacing the surfacing, the other aims of this scheme are to improve safety around Church Bank and to 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.
"Road closures mean the works can be completed as quickly, efficiently and safely as possible and we thank motorists in advance for their patience."
