National Highways is planning a series of improvements along the A38 between Bodmin and Plymouth, after the road recorded a higher than average number of collisions.
Government statistics show that collision numbers at junctions on the A38, particularly between Liskeard and Trerulefoot, are 34 per cent higher than the regional average.
The agency said it has been working closely with Cornwall Council and Devon and Cornwall Police. Following recent stakeholder meetings, local communities will now get the chance to see the proposed safety improvements.
The scheme follows a speed reduction programme introduced between Carkeel and Trerulefoot last year. It will target safety upgrades at the Lean Quarry, Menheniot, Tencreek Cottage and Castle Air junctions, along with other layout, access and visibility enhancements. The aim is to reduce the number and severity of incidents.
Proposals include junction modifications, improvements to road alignment and visibility, and better signage and road markings.
Jack Mason, South West road safety manager for National Highways, said: "Road safety is, and will always be, our number one priority, and we’re constantly exploring ways to reduce the number and severity of incidents on our roads.
"As part of recent road safety studies, we’ve analysed collision data, and investigated traffic flows and movements around junctions and adjoining slip roads on the A38 between Liskeard and Trerulefoot.
"We've been liaising with police and local authority partners to identify a number of interventions and the engagement event will provide an opportunity for businesses and communities to get a better understanding of our proposals."
Data released to local road safety campaign group Safe38 last year showed a large decrease in incidents on the A38 in the Glynn Valley, thanks in part to new speed cameras and AI cameras installed along one of Cornwall's deadliest roads.
The killed and seriously injured (KSI) rate for the section between Dobwalls and Bodmin declined dramatically since average speed cameras were installed along the busy route.
Collision data from National Highways shows that in the five-year period from June 2020 to May 2025, deaths and serious injuries were down 45 per cent on that section compared with the five years before the camera scheme was implemented.
Just 12 incidents on that stretch were classified as serious or fatal from June 2020 to May 2025, compared to 22 incidents between 2015 and 2019. That is a 50 per cent drop.
James Millidge, chairman of the Safe38 action group, said: "We can’t emphasise enough how positive this data is. It demonstrates unequivocally that these safety measures have saved lives and made an improvement to people’s livelihoods."
A public exhibition will be held on Monday, October 5 at Liskeard Public Hall between 1.30pm and 6.30pm. Further information is available on National Highways' South West Safety Schemes web page.
