A Local Shortage of Grit?

The Nottingham Evening Post has been closely following the Notts grit shortage saga.

Despite having fully-stocked up on salt before winter, the paper reports that the County Council's remaining stocks are now low, that deliveries are uncertain and less than expected. The Council is now looking at reducing the roads it grits to only category A and B routes.

Meanwhile, the Northern Echo reports that at Durham County Council, supplies of grit are running low despite having fully stocked up before winter. Apparently deliveries are uncertain and less than expected. The Council is now rationing spreading to category A and B roads.

The Northern Echo article also goes on to helpfully explain that salt defrosts ice by lowering the freezing point of water, but it becomes less effective below about -5C. It also becomes less effective if there isn't much traffic about to mash the salt into smaller particles and spread it around.
