Signs in the Hindhead Tunnel

Reported via desktop in the Electronic Sign (NH) category anonymously at 20:59, Fri 11 August 2023

Sent to National Highways less than a minute later. FixMyStreet ref: 4883588.

The signs in the tunnel are often random speed limits part the way through they will Drop to 40 and then national. It is dangerous and happens at least once a week. Either signs are faulty or not all turned back to national . I have been nearly rear ended a number of times or had people brake sharply to go from 70 to 40. This morning a prime example of it and which resulted in me being flashed and hooted where the van behind me hadn’t seen the change. Also the tunnel is filthy and hasn’t been cleaned in at least 3 years.

Updates

  • Thank you for submitting this report The tunnel is cleaned regularly during the maintenance closures which occur approximately every 6 weeks, with an alternating closure between North and south, so it means each “Bore” is cleaned once every 12 weeks. Unfortunately, due to the nature of a tunnel some sediment build-up is to be expected, as the tunnel is not water tight and over time particulates get drawn through the gaps in the tunnel walls. With regards to the speed limits within the tunnel; It is monitored by a radar system that is calibrated to detect possible hazards within the tunnel, this could be anything from a slow moving or stopped vehicle to pedestrians or animals (which are prohibited within the tunnel) due to the sensitivity of the system, sometimes vehicles driving in a certain manner can trigger an alarm. These alarms automatically implement a safety procedure that reduces the speeds in the tunnel to 40mph until an operator in the control room can verify whether the alarm is due to a genuine hazard or a false alarm, at which point the alert will be promptly cancelled or amended accordingly. Should a speed limit repeater sign become faulty, it will blank rather than show an incorrect speed. I hope this information is helpful

    Kind regards National Highways
