Smoke will continue to blow across the High Dyke, forcing a two-day road closure.
Firefighters have been working since 12.40am this morning to bring the fire at Mid UK Recycling, on Barkston Heath, under control and say “good progress is being made”.
They found 550 tonnes of recycled carpet ablaze, giving off copious amounts of smoke.
The stretch of the High Dyke between the A17 and A52 will remain closed for two days as a safety measure.
Meanwhile, the A153 between Honington and Sleaford, plus Ermine Street, will reopen shortly.
