Travellers have set up camp close to the M6 motorway in Staffordshire.
More than a dozen vehicles are parked in a side road, off the A449, at Acton Gate.
Witnesses said they arrived on Thursday afternoon and stayed near junction 13 of the M6 for Stafford, at the weekend.
It is believed a court order could be secured today to force them to move on.
Veronica Downes, area county councillor, said they expected them to move on but if they did not, enforcement officers from South Staffordshire District Council would secure an order to remove them. Vehicles were near an Argos distribution centre.
In January seven caravans and 10 other vehicles were on Hilton Main Industrial Estate, Essington.
