Residents are being invited to share their views on proposals to install average speed cameras on a stretch of the A3083 in Helston.
The council is proposing the safety measures, which would also see the speed limit reduce from 60mph to 50mph, on the section of road running alongside RNAS Culdrose.
This location has seen several fatal road collisions over recent years, with inquests identifying excess speed as a contributory factor.
Almost 2,000 residents signed a petition calling for speed cameras on the road after the last fatal collision and following an inquest in November 2025, Cornwall Coroner Guy Davies stated that action was needed to prevent further loss of life.
Dan Rogerson, Cornwall Council cabinet member for transport, said:
“One person killed on our roads is one too many. On this particular stretch, several young people have had their lives cut tragically short, and others have suffered serious injuries.
“This is a scheme that we have wanted to bring forward for some time and with joint funding secured from Vision Zero South West and ongoing support from RNAS Culdrose, we are now in a position to bring these proposals to consultation.
“Speed data shows that the majority of drivers are travelling at, or below, 52mph along this section of road which suggests that lowering the limit is unlikely to affect journey times. Where it will make a difference is safety - this is a wide road where travelling at an inappropriate speed can have catastrophic consequences. Introducing cameras and a lower speed limit will help reduce the likelihood of further tragedies.”
The proposed safety measures will be jointly funded by Cornwall Council and the Vision Zero South West Partnership.
Adrian Leisk, Head of Road Safety at Devon & Cornwall Police, said:
“Sadly there have been numerous serious and fatal collisions on this road which have involved excess speed and the community has rightly called for action.
“Average Speed Camera systems are extremely effective at lowering speeds. Our sites throughout Devon & Cornwall have a compliance rate of over 99%.
“We are proud to be working with Cornwall Council to help fund this scheme, which we believe will save lives in this area.”
