Fort Madison continues to clear the way for Amtrak to move its operations across town to the former Santa Fe Depot in Riverview Park.
The North Lee County Historical Society has a lease in place, through 2040, that allows it to use the complex for display and storage.
That agreement has now been amended.
City Manager Byron Smith says the historical society has agreed to relinquish the eastern 2/3 of the main building. He says the organization will also make more space available if requested by Amtrak in the future.
