An organization trying to raise money to build a new museum at Fort Campbell says it has scaled back plans for the project. Fort Campbell Historical Foundation Executive Director Robert Nichols says changes in the design will cut the cost for the Wings of Liberty project in half. Originally, the organization had planned a two-floor, 80,000 square-foot structure at a cost of about $40 million. New design plans call for a 60,000-square-foot, single-story facility at a cost of about $20 million. Nichols says the changes were necessary due to economic conditions. Everything is in place to move forward except the funding, Nichols says, adding that foundation board members recently decided on a strategy to raise the money and open the facility in three years.
