The road will be closed northbound on 7 and 14 February between junction 50 (Baldersby) and Scotch Corner and southbound between Scotch Corner and junction 51 from 8pm until 6am. There will be an additional northbound closure on 8 February from 8 pm until 1 am, and southbound between 1am and 6am on Monday 9 February. This additional closure is necessary for the installation of a new safety barrier to protect the scaffolding for a bridge pier construction.
Clearly marked diversion routes will be as follows.
For closures on 7, 14 February
North bound closure between junction 50 and Scotch Corner junction
Long distance traffic will be diverted from junction 49 (Dishforth) via A168, A19 and A689 to re-join the motorway at junction 60.
South bound closure between Scotch Corner junction and junction 51
Long distance traffic from the West will be diverted north from Scotch Corner to junction 60 and will then follow A689, A19 and A168 to re-join the motorway at junction 49 (Dishforth).
Long distance traffic from the North will be diverted from junction 60 and will then follow A689, A19 and A168 to re-join the motorway at junction 49 (Dishforth).
Local diversion routes serving Catterick and Bedale will also be in place.
For closure on 8 February
The diversion route for long distance traffic will be the A68 (West Auckland), A688 (Staindrop and Stainton Grove), A67 (Barnard Castle), Newgate/Westwick Road, and the A66. This diversion route is approximately 40 miles long and drivers will be advised to add an extra 50 minutes to journey times.
The closures have been carefully scheduled to minimise disruption to drivers and will be put in place when traffic flows are at their lowest.
The work is part of a £380 million scheme to upgrade 12 miles of the A1 between Leeming and Barton to motorway standard. Following the decision on the route of the proposed local access road, work on the remaining section, between Scotch Corner and Barton, will start in due course.
