INDIANAPOLIS — The RCA Dome will be reduced to rubble Dec. 20.

The Indiana Stadium and Convention Building Authority says the former home of the Indianapolis Colts will be imploded on the Saturday morning before Christmas.

Officials say that by then, about half of the dome will have been demolished by traditional methods. The implosion will demolish the upper-level seating area.

The dome's fabric roof was deflated last month and is being cut into pieces to be used by Indianapolis parks for umbrellas at city pools or as shelter covers in parks.

The Colts now play in the nearby Lucas Oil Stadium. The area cleared by the demolition of the RCA Dome will be used for the expansion of the Indiana Convention Center
