Cincinnati Museum Center officials will decide soon on which firm will renovate the art deco landmark.
Last year, taxpayers approved a five-year, quarter cent sales tax to fund repairs to Union Terminal.
According to a statement, BHDP Architecture, GBBN architects and Quinn Evans Architects are the three finalists. The first two are Cincinnati-based companies. The third is based in Washington D.C. and Ann Arbor, MI.
Teams will present proposals in the coming weeks.
A final decision is expected by early April.
