THE gritters are out in full force tonight to ensure that vehicles will be safe on roads across Bolton.

Bolton Council's team of gritting drivers are carrying out a full route grit tonight.

The team took to the streets at about 7pm to begin the operation.

Some 317 miles of main traffic routes will be treated, covering about 51 per cent of the borough's total road network.

Dependent on the weather forecast, precautionary gritting operations commence in the early evening and are fully completed prior to midnight.
