Bucks will run out of salt by Monday

And with more snow forecast for the weekend, it is salting only priority roads to make supplies last, as per the council's emergency plan drawn up on Wednesday.
Stocks of salt that were scheduled to arrive before the end of the year have still not arrived.
And with temperatures falling well below zero drivers are being warned that salt becomes less efficient at melting ice once the air temperature drops to around minus five degrees C.
To conserve stocks, Buckinghamshire County Council is today treating secondary roads and footpaths with grit which breaks up surface ice and helps tyres to grit. It has also pledged to top up grit bins in towns and villages today.
Mark Averill, network operations manager of Transport for Buckinghamshire, said the county had enough supplies of grit and salt to deal with the anticipated weather until Monday at most and he warned householders not to take salt and grit out of bins for use on their drives.
He said: 'It's important to remember that salt bins are for helping users on the roads and foot ways, and not to be taken for private use."
He said the council was well prepared for winter at the beginning of the season, with salt barns at maximum capacity, but the severity of the weather has drawn on supplies much more quickly than planned.
He said: "Even before the first fall of snow, we had anticipated the impact of the severe weather and had ordered extra supplies of salt.
"We're awaiting fresh deliveries but there is uncertainty across the country about salt supplies, which is why we've taken measures to conserve our supplies."
Valerie Ethereal, Buckinghamshire County Council cabinet member for Transportation said: 'Our gritting teams have been working in the teeth of the bad weather, turning out at all hours in their endeavours to beat the snow, and at times putting themselves at some risk to serve the public. But we can only do what we can do - people have to adapt and temper their expectations.
"We have successfully kept all main routes open, and the secondary routes accessible wherever possible, throughout a prolonged period of extreme weather - the worst in 30 years. We managed this only by judicious and prudent use of salt supplies and by sticking to our winter maintenance programme."
