Dear Sir / Madam,

A1 Wansford to junction 17 (Peterborough): safety barrier upgrade and other maintenance

I am writing to inform you of upcoming resurfacing works, as part of the current package of safety improvements and maintenance activities on the A1 between Wansford and junction 17, Peterborough.

We plan to complete this work over two weekends in March with one additional weekend planned for contingency.

Closures and diversions

To carry out the work safely, we will need to close the A1 southbound between Wansford and junction 17 and divert traffic as detailed below:

 A1 southbound closure between Wansford and Alwalton junction – Saturday 11 March, 6am to Monday 13 March, 6am.

  • A1 southbound closure between Wansford and junction 17 (Peterborough) – Saturday 18 March, 6am to Monday 20 March, 6am.
  • Contingency weekend for A1 southbound closure between Wansford and junction 17 (Peterborough) – Saturday 25 March, 6am to Monday 27 March, 6am (this may not be required).

Whilst the A1 is closed, southbound traffic will be diverted from the A1 at Wansford and directed to follow the A47, A1260 Nene Parkway and A1139 Fletton Parkway, before re-joining the A1(M) southbound at junction 17, Fletton Parkway Interchange.
