Motorists are being warned that the A1 will be fully closed tonight as repairs continue after a sinkhole opened up in Gateshead.
The 3m deep hole was discovered on the northbound carriageway near to the Lobley Hill Interchange on June 25. The hole has now been filled with a specialist concrete mixture and holes were drilled to pump more material underneath the repair to prevent further collapse. However, work to repair the surrounding road is ongoing.
Highways England has confirmed the A1 will now be closed from 8pm between junctions 67 (Coal House) and 68 (Lobley Hill) as contractors remove a contraflow and re-install barriers.
Work is expected to continue through the night to ensure the carriageways will be safe to re-open by 6am on June 29 (Wednesday).
Lynne Biddles, Highways England Project Manager, said:
Highways England has issued to following advise to drivers:
For local traffic a diversion will also remain in place through the Team Valley trading estate between junctions 67 and 68.
Longer distance traffic will be advised to use the A19 eastern route around Newcastle and Gateshead as an alternative to the A1 - and toll barriers for the Tyne Tunnel have been lifted. Some planned closures for roadworks on the A19 have also been suspended.
A1 traffic heading further north towards Scotland will be advised to use the A66 from Scotch Corner across to the M6. Some roadworks on the A66 have also been suspended to help this.
Road users will be advised when the carriageway has re-opened.
