6:30am: Buses affected by snow on Sheffield's roads
Bus passengers have been warned to expect delays and alterations to services this morning because of heavy snow in some parts overnight.
First South Yorkshire said a combination of snow and ice has made it 'unsafe' to operate on some roads.
A company spokesman said: "After overnight snowfall, and some further accumulations this morning, particularly on local estate roads and on higher ground, coupled to freezing temperatures, there are some current impacts to local bus services.
"Most of these issues are the result of icy road surfaces making it unsafe to run on certain roads.
"Overnight gritting has taken place across the network, and the current list may change rapidly.
"Please note that the depot teams are checking routes now - most of the list below is the current list as carried over from late evening on Tuesday. As soon as more reports received, these will be shared.
"If you are travelling, please remember to take extra care on untreated surfaces such as pavements, wrap up warm and leave a little extra time for your journeys."
