A1 Improvement Scheme


On Saturday 29th July 2017, the local access road between junction 52 Catterick and junction 51 Leeming will be available to public traffic. On the same evening, we will also re-open Low Street junction which provides access to and from Kirkby Fleetham, Great Fencote and Little Fencote.
Over the coming weeks, we will need to maintain temporary 30mph speed limits on the local access road. These speed limits will be in place for both the protection of our workforce and the public, as there will be remedial works still on-going. The local access road will not be formally handed over to the local highways authority (North Yorkshire County Council) at this point and will remain part of our scheme for some time.
We would once again like to thank you for being patient with us and for your support for the scheme so far. If you would like to discuss any aspects of our works, please contact our Public Liaison Team on 01677 932 348 or enquiries@a1l2b.com.

  1. Can you post me picture of how it will all look once it’s complete? It’ll be useful to know where all the roads and bridges link up when it’s all complete.

    1. I only have a map on paper which is extremely large of how everything should look once complete. I am sure there is probably something on the Highways England website although at this present moment I cannot find it. I will contact A1L2B to find out if they can point me in the right direction. Perhaps you could take a look at their website too and if you find it let me know. If I there is something available I will put it on the website.

  2. Hi, I’ve just been reading the newsletter and looking at the plans above and I’m still a little confused! Is the access to the A1 north to be permanently closed? If so, where will the access be?

    1. Hi Nicola
      There will be no access to the A1 North at Gatherley Road, similarly there will be no exit from the A1 South onto Gatherley Road. There are a couple of ways that you could get onto the A1 North from Brompton. Firstly there will be an exit from Gatherley Road (where you currently join the A1 North) onto the Local Access Road. The LAR runs virtually parallel with the A1 and you will be able to travel North and South on this road. You would access it at Gatherley Road and travel north to Scotch Corner where you will then be able to join the A1. The other option to join the A1 would be to use the new Fort Bridge (when it has been put in place) and get onto the A1 via the new Catterick Central Junction.

      If you would like to have a look at a map you would be most welcome. you can contact me, the Parish Clerk, by email or telephone.
