Cincinnati is planning a riverfront memorial built around the tower from a Cold War-era nuclear-powered submarine that shares the city's name.
The city once hoped to acquire the entire USS Cincinnati and make it into a naval museum. But the plan that won unanimous support from the city council in 1994 was later turned down by the U.S. Navy, which wanted to keep the sub's design classified and had concerns about the nuclear components.
The Navy has now agreed to donate the sub's T-shaped tower, which alone weighs about 35 tons. Officials say trucking it in pieces to Cincinnati from a naval shipyard in Washington state will cost about $80,000, which will need to come from private donors.
