Construction on a new multipurpose arena that would be home to the Detroit Red Wings could begin before the end of the year, according to a report by Crain's Detroit Business.

Economist Mark Rosentraub, a professor of sports management at the University of Michigan, told writer Bill Shea of Crain's that the building would likely take as long as two years to build.

Rosentraub had done work for the Ilitch family, which owns the Red Wings, and is reportedly familiar with their plans although he said he has not spoken with the Ilitches this year.

"I would hope that they would be able to get it in the ground by the fall," Rosentraub said in the Crain's Detroit Business story. "A lot of that depends on the infrastructure. Most of the infrastructure is already there. You don't need new access to the freeways or widening the street."

Olympia Entertainment, which is owned by the Ilitch family, announced in December that it was hoping to see a $650-million multipurpose facility built to replace Joe Louis Arena as the Red Wings home.

Crain's said that three sites in downtown Detroit are being considered for the arena.
