The River Way, which runs through an industrial estate home to several businesses, was this morning covered in large smoke plumes that called for the attendance of emergency crews and forced the closure of the roundabout at the junction with A414 Edinburgh Way. Residents of the area have been urged to keep the doors and windows of their homes shut.
It is not yet known whether any of the offices in the impacted area are affected by the blaze.
Essex Fire Service said: “Crews are currently tackling a fire on River Way in Harlow.
“There are six fire engines at the scene, so the road is partially blocked.
“We’re asking people to avoid the area and find another route where possible.”
It added in a statement an hour later: “We have increased our attendance to eight fire engines, and are joined by two from LFB (London Fire Brigade).
“There are large smoke plumes over Harlow Town – if you live locally, please keep your doors and windows closed.”
