A Lancashire site expecting to see 861,000 sq ft of warehouse development is to move forward.
A consortium of Lancashire County Council, Maple Grove and Brookhouse Group have started site works at the 160-acre Cuerden site, near Preston.
The £430m development close to the M65 motorway will also see offices, retail, hotel and up to 17,000 new homes.
The development, on a site owned by Lancashire County Council, will take a decade to complete.
The start of site works means decisive progress on a site that has long been a priority for development by the county council.
