16 to 19Jan26 A1 Southbound closure

Works

We'll be moving the A1 southbound onto a new stretch of road over a newly built culvert.

A culvert is a structure that allows water to pass under a road, preventing flooding and erosion.

Closure

We'll close the A1 southbound between Wyboston and Tempsford from 9pm Friday 16 to 5am Monday 19 January 2026.

Diversion

  • exit A1 southbound at Wyboston junction
  • take A428 towards St Neots
  • join St Neots Road southbound towards Tempsford
  • re-join A1 at Tempsford junction
