Wire Regeneration has appointed a contractor at Wilderspool Stadium to clear the site to make way for Warrington's Southern gateway redevelopment.
The former home of Warrington Wolves Rugby League Football Club will be pulled down by Buckingham Group Contracting, with the first stage of demolition expected to complete in October.
The stadium was vacated by the club following its move to the Halliwell Jones stadium in 2003 and since then has been used for Wolves' junior and academy matches.
Wire Regeneration was formed in March 2014 as a joint venture between property company Langtree and Warrington Council to deliver regeneration and development activity. Details of a masterplan are expected to be announced soon.
John Downes, chief executive of Langtree, said: "The appointment of demolition contractors is a significant step in allowing us to push forward and deliver the masterplan for the southern gateway.
"This area of the town has an enormous potential to become a new centre of employment and retail, along with new residential areas. Just as the Wolves have gone on to write new chapters in their history in the Halliwell Jones stadium, we are working to give this part of Warrington a new lease of life."
