Two photocopied pieces of paper taped to the front door of the Brown v. Board of Education National Historic Site is letting visitors in Topeka know the building is closed because of the federal government shutdown.

Across Kansas, thousands of government employees were reporting to work Tuesday to prepare their offices for the shutdown, which officially began shortly before midnight.

The lack of a resolution to the federal budget means thousands of employees at the Army’s Fort Riley and Fort Leavenworth will be furloughed until a new spending bill is approved. Employees were being notified which positions would be impacted.

The shutdown is also affecting the state’s National Historic Sites, like the Brown building in Topeka, which honors the U.S. Supreme Court’s landmark school desegregation ruling in 1954.
