Pittsburgh was one of 35 American cities that the U.S. Olympic Committee encouraged in February to submit a bid.
According to Channel 11’s news exchange partners at TribLIVE, that isn't going to happen.
Mayoral spokeswoman Marissa Doyle said in an email that there wasn't enough community support for such a bid.
Allegheny County Executive Rich Fitzgerald agreed the greater Pittsburgh area never rallied around the idea.
Fitzgerald said, "It would cost two to three billion -- that with a `b' -- dollars" which he called a "big risk."
About 10 cities have expressed interest in bidding, including Philadelphia, Dallas, Los Angeles and San Diego. The U.S. committee must decide by 2015 which bid to support.
