Bidders battle for Middle River Station

With back-to-back bids, three bidders had sent the auction price for a former World War II bomber plant in Middle River to $18.4 million by Friday afternoon, according to the Web site conducting the auction.

If no bids are made over the weekend, the highest bid at midnight Friday will win, according to MaryAnne Beatty, a spokeswoman for the U.S. General Services Administration, which is conducting the sale.
