In 2020, the Programmatic Agreement Among the Advisory Council on Historic Preservation, the Federal Highway Administration, the Missouri State Historic Preservation Officer, and the Missouri Highways and Transportation Commission Regarding the Treatment of Historic Properties that might be Affected by Improvements to the US 169 Corridor from Missouri Route 9 to Interstate 35, MoDOT Job Number J4S3085, Clay and Jackson Counties, Missouri was executed. In accordance with Stipulation 13, the Missouri Department of Transportation is requesting to amend the agreement to change Stipulation 3.C.(2) due to lack of local support for a traveling exhibit as originally proposed.
