Winter salting routes

Winter Maintenance is co-ordinated across the county by Hertfordshire Highways, who are on 24-hour stand-by during the season.

The actual salting is carried out by a fleet of salting lorries. This is also known as 'gritting' or 'spreading' but salt is used to help prevent ice forming on the roads. Over an average winter, they will be deployed about 40 times, usually at night. On every trip they treat over 42% of Hertfordshire's entire road network – about 2,500km (1,553 miles).

They cover 58 different routes across the county, in priority order:

1. A roads but not motorways or trunk roads
   
2. B roads one entrance/exit to each village
   
3. Bus routes

Should snow fall the roads will be cleared in the same priority order.
