"In 2019, U.S. Sen. John Cornyn and U.S. Rep. Sheila Jackson Lee, both of Texas, introduced the Emancipation National Historic Trail Study Act, which started a Park Service feasibility study of the proposed trail and its historical significance. The study’s findings, expected by the end of 2023, will be shared with Congress, which could then designate it a national historic trail. That would allow for a management plan and marking historical sites as permitted by private landowners."
