DETROIT -- Detroit's Cobo Convention Center was once crumbling, but now millions of dollars in renovations are breathing new life into the building.

It all comes just weeks after a regional authority assumed operational control of the venue, which is nearly a month away from hosting the North American International Auto Show.

So far, there have been more than $3 million in electrical upgrades and repairs to the roof and loading dock. "The responses that we've had from show management have been very positive," said Tom Tuskey, Director of Cobo Center.

Renovations still have a long way to go. An estimated $288 million is expected to go into Cobo.

An expansion will likely happen sometime next year.
