"Our winter service runs from October 1 to April 30. During this time our team of 21 staff and 19 gritters are on standby 24 hours a day, seven days a week ready to deal with whatever the winter weather may have in store for us.
"The Streets Ahead team are responsible for precautionary gritting across the city. This means that our fleet of 19 gritters will grit the roads when freezing temperatures are predicted.
