The Federal Highway Administration is reviewing the prices Indiana paid to acquire land for highway projects across the state.
The Indianapolis Star reported Sunday the portion of the federal investigation conducted at the Indiana Department of Transportation's Indianapolis office concluded last week, but officials are still analyzing that they found.
The Star says similar reviews have stripped local governments of federal funds.
The Star recently reported Indiana offered $7 million for 32 properties that its appraisers valued at less than half that amount.
INDOT spokesman Will Wingfield says the agency follows state and federal laws for acquiring land and is working with the FHA on the review.
Gov. Mike Pence has told his top ethics officer to look into land acquisition payments to an INDOT official and his relatives.
