One month of night-time southbound A1 closures to start next week

Please be aware that the southbound A1, between Harlaxton and Little Ponton, will be closed to traffic overnight (8pm to 6am) for five weeks, starting on Tuesday 6 April.

The diversion route for the closures will be via the B1174 through Grantham rejoining the A1 at Little Ponton.


These works will allow the contractor to safely carry out essential works to the A1 as part of the Grantham Southern Relief Road project, including:

  • Drainage and ducting installation
  • Constructing a new surface water channel
  • Installing new signage and street lighting


Additional night-time closures will be required this summer, starting in June, for final works to the A1 ahead of opening the new relief road junction later this year.


Please don't hesitate to get in touch with any questions. 


Best wishes
