Drivers are being warned about work starting tonight to replace the bridge joints on Blaydon Haugh Viaduct on the A1 in Gateshead.
Highways England will be replacing the bridge joints on both sides of the carriageway between junction 73 (Derwenthaugh) and junction 74 (Scotswood)b from 23 January.
Work will start on the southbound carriageway and temporary road plates will be fitted over the bridge so the route can remain open during the day.
The work will be carried out overnight between 8pm and 6am and a temporary speed limit of 50mph will be in place.
Once work is completed on the southbound carriageway, work will then start on the northbound carriageway.
