The Logan County Transportation Museum addition opened in April 2014. The building was designed by architect Karen Beasley of Beasley Architecture and Design in Bellefontaine. It was designed in the spirit of the Big Four/New York Central Roundhouse railroad that stood in Bellefontaine from the late 1890s to the 1960s.
The building was made possible through a Transportation Enhancement Grant from the Ohio Department of Transportation. The ODOT grant paid 80% of the $3 million project. The Historical Society raised the rest of the money through donations from local businesses, industries and individuals. The complete list of donors can be seen in the entry of the Transportation Museum, as well as a dedication board acknowledging many individuals who played a key role in the project.
The first floor bays are dedicated to numerous exhibits on Logan County’s important role in transportation.
The second floor houses the Logan County Genealogical Society and their library and the Logan County Historical Society’s Archives, as well as the AcuSport Meeting Room.
