Each year, between October and March, we survey the condition of our highways. We do this using a specialist vehicle called ‘SCRIM+’ (Sideway-force Coefficient Routine Investigation Machine).
SCRIM+ collects data on range of condition aspects, which allows us to respond to any arising maintenance issues and helps ensure road users continue to travel safely.
Check the table below for the survey start and end dates for the 2024/25 SCRIM+ survey programme in each area.
