On March 9, 2013—the 100th anniversary of Tubman's death—the State of Maryland and the National Park Service broke ground for a new protected area within the Blackwater National Wildlife Refuge. This 17-acre state-owned site was designated a state park, and named the Harriet Tubman Underground Railroad State Park. The Maryland Park Service and the National Park Service jointly provided funding to construct the Harriet Tubman Underground Railroad Visitor Center. On the same date, the State of Maryland unveiled the 125-mile Harriet Tubman Underground Railroad Scenic Byway, a route along an existing system of county, state, and federal roads which mirrored the route Tubman took while rescuing slaves.
