HEAVY snow flurries brought more disruptions to parts of South Yorkshire this morning - with buses cancelled, roads brought to a virtual standstill and some schools closed.
Weather forecasters say around five centimetres were due to have fallen this morning.
Meanwhile Stagecoach is not running on hilly routes and also has severe delays.
A South Yorkshire Passenger Transport Executive spokesman added: “Operators report that several areas of Sheffield are gridlocked with traffic which is causing severe delays.”
Between Sheffield and Chesterfield, Stagecoach bus services 43/43A, 44/44A, X17, 50/50A, 80 and 84 were delayed or disrupted.
Trains and trams have been operating with delays.
Events have been cancelled, including a tea dance at Sheffield City Hall.
Ten Sheffield schools are closed - ■Bents Green, High Green, King Ecgbert, King Edward Lower and Upper, Mosborough Primary, Norfolk Park Primary, Rowan, Talbot, Totley All Saints and Woolley Wood.
Others opened later.
Sheffield Council said that Streets Ahead, run by contractor Amey, has been working to capacity to grit roads and keep Priority One routes running.
Resources have been diverted from other highway maintenance work to clear roads, footways at principal shopping areas, around hospitals and in the city centre together with refilling grit/salt bins, and bags for Snow Wardens.
Coun Jack Scott, cabinet member for environment, recycling and streetscene, said: “The snow this morning, much of which came in during rush hour, created particularly hazardous driving conditions.
“The full Streets Ahead team worked through the night to treat the roads but the nature of the weather made the situation difficult – with last night’s gritting preparation being washed away by the rain, as well as the heavy snow just before the morning rush hour period.
“Despite this, Priority One routes have all remained open and clearing of Priority Two routes has taken place as resources allow.
“We are expecting a very large band of snow during the afternoon. This is expected to turn into sleet and then rain.
“We want to reassure people that Streets Ahead is doing all it can to keep Sheffield moving during the snow. We urge people to take care when travelling and allow extra time for journeys.”
Bin collections were also delayed in Sheffield.
A Veolia spokeswoman said: “Waste and recycling collection services have been working today.
“However, due to the bad weather and conditions of the roads and footpaths, the start of today’s collections was delayed. “This delayed start will mean that we are unable to complete all collections.
“If your bin/box has not been emptied by 6pm, your collection will instead take place on Saturday.
“If your collection is due on Wednesday 6th February, please present your bins/boxes for emptying as normal.”
Weather forecasters say around five centimetres fell this morning - but a predicted band of wintry weather for this evening will now be rain and wash away the snow.
Black ice and snow caused hazardous conditions earlier today, making driving difficult on many main roads, with side roads hit worst of all as gritters turned out to tackle the snow fall.
One lane of the M1 northbound in South Yorkshire, was blocked between junctions 36 and 48.
The Snake Pass and Woodhead Pass were amongst the first road casualties and traffic bosses announced the two links between the region and Manchester were closed.
Sheffield, Rotherham and Barnsley traffic was reported to be very slow traffic. Doncaster appeared to miss the worst of the bad weather.
In Sheffield, traffic was crawling on major routes such as Mosborough Parkway and Ecclesall Road.
Emergency services warned people to take care on icy roads.
An Ambulance Service spokesman said it was prepared for weather-related falls by people and road traffic collisions, especially during the rush-hour.
Most schools were preparing to open as normal, with a few closures and some plannning to open later this morning, depending on conditions.
