HARRISBURG (AP) – PA is undertaking a comprehensive examination of the stories told by its 2,500 roadside historical markers. It’s a process that’s found factual errors, inadequate historical context, and inappropriate references. So far the state has removed two markers, revised two, and ordered new text for two others. Disputes about how historical markers should be worded or whether they should exist at all have divided communities across the country in recent years. In PA, the new markers getting approved are increasingly telling the stories of previously underrepresented people and groups.
