The demolition of the Austin Convention Center continues Monday, Sept. 8, 2025. After nearly six months of demolition, crews began construction on the Austin Convention Center’s $1.6 billion expansion and redevelopment. While demolition of the existing buildings continues, contractors have started building diaphragm walls — deep, concrete barriers installed underground to keep soil and water out so workers can safely dig basements and foundations.
