The iconic Williams Stand - named after former chairman, Des Williams - was built in 1958. The near 60-year-old stand houses home fans only and features some old wooden seating alongside the new premier seating.
In its lifespan, the Williams Stand has seen tears, glory and over a million Bristol City fans.
The Wedlock Stand has already been demolished and will be replaced with a new six thousand-seater South Stand. And the Dolman Stand will see a complete remodelling, including new lower seating tier and Dolman Conference and Exhibition Hall.
Bristol Sport chairman Martin Griffiths said: "The redevelopment of Ashton Gate has been a complex project, and just to get to this stage, has been very challenging.
“As we now enter the final weeks of the construction of the South Stand and the complete refurbishment and modification of the Dolman Stand, demolition of the Williams begins.
“We thank supporters for their patience and really look forward to welcoming everyone back to the new Ashton Gate Stadium at the start of the football and rugby seasons.”
The newly re-vamped Ashton Gate Stadium will become the largest conference and events venue in the South West with a capacity of 27,000 and is due for completion in July 2016.
Three phases of work are now underway simultaneously at the home of Bristol City FC and Bristol Rugby:
•Phase 1 – demolition of the Wedlock Stand, replaced with the new 6,000-seater South Stand
•Phase 2 – complete remodelling of the Dolman Stand, including complete new lower seating tier and Dolman Conference & Exhibition Hall
•Phase 3 – demolition of Williams Stand and construction of new 11,000-seater, two-tier, West Stand
