The programme is designed to ensure the motorway remains safe, reliable, and resilient for up to 50,000 drivers who rely on it daily.
With over 1,200 tonnes of road salt delivered - equivalent to more than 40 articulated lorry loads - and an additional 58 tonnes of white salt stocked for brine tanks, operators say the M6toll will be fully equipped to tackle frost, ice and snow.
To maintain optimal performance, 1,000 tonnes of existing salt have been rotated and refreshed to prevent clumping and hardening, ensuring immediate usability.
All winter maintenance vehicles and snow ploughs have completed their summer servicing and are primed for deployment.
Refresher training is underway for operatives and duty officers, reinforcing the readiness of frontline teams.
“Our winter preparations go far beyond snow and ice,” said Alex Sheldon, head of operational delivery.
“We’re planning for everything from seasonal storms to exceptional rainfall events.
“It’s about keeping the motorway safe and dependable, no matter what the season brings.”
