The Indianapolis Airport Authority continues to work on plans to demolish the old airport terminal.

Airport Spokesman Carlo Bertolini says it'll likely cost in the $5 million range to tear down the huge building and concourses. Bertolini says they're also entertaining offers and ideas about what to do with the 80 acres once the terminal is torn down. Bertolini says they've already demolished one nearby building.

The authority has been searching for companies interested in redeveloping the terminal lot in addition to several other land parcels since 2008 when the new $1.1 billion terminal opened. He says they're trying to figure out the most feasible and environmentally-friendly way to demolish the terminal given asbestos and other issues in the structure.

He says the old garage will remain. Cleanup is continuing on the parks building which has been torn down and is not attached to the old terminal. Bertolini says redevelopment would likely include transportation or aviation interests.

Meantime, Radisson Hotel General Manager Stephen Wright says he and other nearby hotels would love to see almost any great new business on the site. Wright says although business continues to do well for the Radisson, things would be even better with more viable businesses in place.
