Parts of Sherwood have been evacuated overnight after a major factory blaze.
Firefighters were called to Sherwood Works in Nottingham Road at around 1.20am on Thursday.
The factory is just behind Sainsbury's, off Valley Road.
Road closures are likely to remain in place for most of the morning and include Westbury Road; Nottingham Road, from its junctions with Perry Road and Northgate; and Lortas Road.
Nottinghamshire Fire and Rescue Service wrote on their Twitter feed that eight crews were called to the blaze.
They later added: "Our Control room is receiving lots of calls about the smoky smell from Lortas Rd fire: please only call if you are reporting a new incident.
"Please be assured we have more than 40 firefighters working hard to tackle the blaze."
A police spokesman confirmed officers had been helping with the evacuation and road closures.
Most of the evacuations were from businsses, including Sainsbury's.
The spokesman said: "There is thick smoke around, making visibility difficult, and people are being advised to avoid the area wherever possible.
"Local residents are advised to close windows as a precautionary measure."
People are being warned that the road closures will effect bus routes into and out of the city.
